FULL FRAME vs APSC vs M4/3 - WHAT'S THE DIFFERENCE?

[@robbyvillabona]

One major reason the OM-1 is such a good deal is for its computational photography features like Live Composite, Live ND, focus stacking, and handheld and tripod hi-res mode. For relatively still birds in difficult lighting you can shoot handheld hi-res at very high ISO's yet get noise free 50MP images.

[@hrvojekant9415]

Great presentation...unbiased! Nice! Thanks ...regards.

[@mistergiovanni7183]

One of the things I like most about your channel is that you don't have a competition to show the most expensive equipment. On the contrary, you show that with good ideas and looking for the opportunity you can do bird photography, probably the genre in which you have to spend the most on equipment, with a moderate budget. Also, beyond your preferences, it is interesting that you show various brands and types of cameras without fanaticism and with good humor. Thank you so much.

[@KyleJones-kk8vw]

These videos are such an important contribution for those making big financial decisions when buying into a new system. I really appreciate how you demystify the options, allow people to make informed choices based on their needs, and emphasize that there is ultimately no “correct” choice, particularly for hobbyists.

Thanks Kyle, you comment means a lot, it is complicated and hard to explain so glad it was helpful, Cheers, Duade

[@TITAOSTEIN]

The OM1 + 150-400mm f4.5 PRO TC1.25 is the best “Crop” alternative for Wildlife (specifically Birds and BiF). The 150-400mm is for many photographers the best Long tele zoom lens ever made!

[@olaeliasson634]

When I looked for a kit this winter I came down to choosing between Sony a74 and the Om-1, ultimatly ended up with the Om-1 for because of the lenses were obtainable within my budget and the size. I hike alot and wanted the smaller form factor, and the weather sealing was also a huge factor. Im more then happy with it, it's more camera then I can master. But having alot of fun with it, walking in nature alot more then I used to. And I have to thank you for the inspiration I found in this channel for that.

[@Dabbelju]

Hi Duade, that’s simply the best explanation of sensor size effects I‘ve ever seen. Great idea to start with the image circle of the lens. It‘s a joy to watch your content, even here where I new most of it before. I really like your calm while also enthusiastic presentation. Your gorgeous example photos add to that also a lot. To show the crop and editing from the RAW is another highlight of your videos. Thanks a lot and keep up the great work!

[@glueckspilz37]

Couldn´t agree more

[@RollTideUK]

I use a Panasonic G9 and the PL 100-400mm for my bird photography. Weight, size and cost were the determining factors in my kit choice. Whilst M43 can have it's limitations I find it's fun to shoot and enjoy wringing everything I can out of it.

[@Stalled-wm3qd]

Ditto! Does plenty of other stuff too including Sports and sunsets. Also I just saw the G9 advertised somewhere here in Australia for under $900. Now that must be a bargain! But now it has been on the market for over 5 years (Dec 2017) so could at least have bird and animal eye focus added to keep in competitive.

[@letni9506]

I paid about £1300 used for my G9 and 100-400. It's about the heaviest kit I want to carry when I'm walking in the countryside. I'm very tempted to try canon out though. It seems that can get some reasonably priced gear at a weight that's not too crazy either.

[@benoutside7593]

You are a very good instructor. Feels like you are talking with us and not at us and not trying to sell people on one item. I have been out shooting and been asked if my R7 was a crop body. Wasn’t real confident in how to answer so I have been studying up. Your video helped me better understand the differences. Ready for that question next time.

[@telkirton]

I was a Nikon user for 40 years film and digital and now sold everything and moved to M4/3, one of the best things I'v done in my 70 years of age.

[@timsmith5339]

I have done a similar thing but gone to Fuji. I'm finding that I'm hankering for heavier Fuji bodies now (I started with an X-E1 and XC lenses which are incredibly light), so my current XT-2 and XF lenses are probably slightly heavier than a DX Nikon!. There is much more to like about a Fuji though, so I'm happy. I would like to try a micro 4/3 someday though, I like what I hear about those too.

[@Jessehermansonphotography]

Definitely the best video to explain crop sensors, and how they handle field of view. A lot of folks trying to explain it don’t do a great job explaining the distance to the subject and such.

[@gliderpilot2006]

Great video! I thought your coverage of the various size sensors was accurate and balanced, they all have advantages and disadvantages and you covered them extremely well. You also gave great examples as to why you might choose one over the other and how you can work around some of the limitations of the smaller sensors (software, distance of target to background, etc.). Thanks for taking the time to show this. Being an OM-1 shooter myself I'm hopeful that I see you occasionally beating around in the bush on future videos with that rig!

[@rlgenge]

As always a great video, showing the comparisons without bias is much appreciated. As a Panasonic m4/3 wildlife (mainly birds) I rarely shoot above F8 and when needed I compensate the more detailed background in post by selecting the background, and running basic noise reduction, often more than once in order to obtain the desired effect.

[@jthommo101]

Hi Duade, an important advantage of the M4/3 bigger depth of field is that it helps to keep more of the bird in focus, especially if it if longways to the camera where, with full frame, the eye might be sharp but the tail blurry. Also, Olympus has a great pro capture mode - Canon has tried with the R7 but, due to rolling shutter, failed miserably.

[@ColinLeslie]

Great comparison and as an OM1 user I agree with all the pros and cons. For me weight and price were major factors along with the great tracking, IBIS and the 60mm Macro but we all compromise based on circumstances. I think you show that it's the photography rather than the tools that are important, Cheers!

[@Duade]

Thanks Colin, I couldn't agree more, congrats on the kit. Cheers, Duade

[@TiaTravelsAround]

This is sooo useful as someone who has been eyeing the OM-D e-M1 mark iii. I still think the crop is worth it for me, I travel full time so weight is a big thing, even the more expensive tele lenses are so heavy!

[@craigb8379]

I own both the E-M1.3 and the OM-1. I would recommend stepping up to the OM-1 if you are able to, depending on your use case. The noise handling is far far superior, which makes a big difference for wildlife shooting as you definitely need to spike the ISO to get the shutter speeds. The subject tracking is also a revelation, if you shoot wildlife. It is worth the upgrade for that alone (ignoring cost from a pure performance perspective). The extra improvements in burst rate, Live ND etc are just the icing on the cake for me.

[@_systemd]

either get em1 mkii and save up money big time, or step up to om-1. I bought mk 2 some time ago cuz did not find mk3 to bring any large benefits for its lot higher price. then I went om-1 , which obviously comes with more power, latest features and some improvements across the board. but it does not do any magic in any way, if budget is concern mk2 is just fine.

[@ÁzsiábaSzakadtam]

[@jtidsskids]

Thank you for producing such a clear and balanced review of the three different sensor sizes. As always any choice is based on a series of compromises; DoF, cost, weight, lowlight noise etc etc in the end you pays your money....

[@Mthompson4545]

Thank you so much for taking the time to put together this video. You did such a wonderful job explaining the differences in the three formats. As an OM-1 user, it was especially helpful to learn about the greater DOF I’m getting and, thus, the less blurred out backgrounds. It hasn’t been a big problem for me, but I will certainly keep it in mind when I’m out shooting.

[@Duade]

Thanks mate, yes, not a massive thing and in fact having more background is often a good thing as it gives more context to the scene. Cheers, Duade

[@giannimoisson4000]

Certainly one of the best comparative tests ever seen on You Tube. Well done.

[@Duade]

Wow, thank you!

[@MrBrabo1]

Hi Duade, thanks for this excellent video. When I look at my own photographs all taken with the R7, the biggest difference in quality of the shots is, as you so rightly mentioned, distance and light. Of course there are differences in equipment, but that is really secondary to circumstances. Cheers!

[@Duade]

Thanks, totally agree, the light and distance will have a bigger impact than the gear most of the time. Cheers, Duade

[@alansach8437]

It's all about the light (and distance). People don't realize, and often don't want to acknowledge, how important good light is to perceived sharpness.

[@T1MBO95]

Love all of your content Duade! I've been using a 90D (APSC) with a Canon 100-400 II and a Canon 70-200 II along with a 1.4x III teleconverter when I'm desprate for more reach. I'm extemely happy with the results I've been able to get! Your videos have offered a wealth of knowlege that have repeatedly proved invaluable in choosing my gear!

[@gavinedmondstone316]

Wonderful explanation and visualization of the differences between the formats, Duade. An additional advantage of m43 for the birding photographer is the compactness of the other lenses in the system. For example the tiny 14 mm pancake lens fits in a pocket in case you wish to capture the habitat that you were birding. If you didn't use it you don't regret having carried it around all morning.

[@andyd466]

That was the best explanation of depth of field between FF/APSC/MFT that I've ever heard! I'm currently looking for a new camera and system and this was extremely helpful. Thank you

[@Duade]

Glad it was helpful!

[@ethanteo3748]

I think you've made a very fair comparison, but it would have been great if you mentioned the stabilisation of the OM-1, which I would say is still 1-2 stops better than the best-stabilised full frame options available right now. I think perhaps you need to be less conservative with shutter speed to notice this. For example, the Kookaburra which you shot at 1/320s and 25600 ISO could have probably been shot at 1/30 or even lower with a good hit rate in a continuous burst. With my OM-1 and 300F4, the synchronised stabilisation system gives me a decent hit rate with 1/2 second exposures (about 40-50%) and 1 second exposures (about 10-20%). These shutter speeds are totally unusable for moving subjects of course, but it shows that the gap in noise performance can be considerably narrowed by dropping shutter speed. Great video nonetheless!

[@_systemd]

he prob did it on purpose for demonstration. but I can agree that in situations without subject movement, there where I would have shoot my DSLR at 1/200 , I use my m43 at 1/25, negating any advantage of the larger sensor and pulling ahead actually.

[@SL-wr5zf]

Holy cow, your videos are the best I've come across. They're so well laid out and edited. I just got back from Costa Rica, where I realized how limited I was by my phone camera to capture the beauty that I was seeing. I bought my first camera, a used FZ1000 for $200, to just practice taking manual photos while I decide on a budget and a camera setup. I'm strongly considering getting an R7 and am going to head over and watch your full review after this video. Thanks!

[@ForrestWest]

Thanks for sharing all of this valuable information! I think the R7 with the RF100-400mm for me is the perfect balance of light weight, reach, image quality and low-light handling. I get 640mm field-of-view and a short minimum focusing distance with good magnification and pre-capture to never miss action in a lightweight, affordable and fun to carry package.

[@denisesavage2382]

Love how you aim to make sense of the differences. I'm impressed.

I own the OM1 and 300 f4 and it’s an amazing combo! I loved it so much I sold my a1 and a7riv and go to OM1 bodies. The 300 f4 is amazing but I’d love to have the 150-400. I rented that lens and it’s phenomenal.

[@hamtairo]

Finally you get to touch m43 and give feedback with regards to it👍🏻👍🏻

[@kimraymond2749]

Great explanation Duade. I also shoot with an Olympus M1 Mark iii. Cost and weight were the determining factor. I use the olympus 75-300 again for weight and cost. approx. A$2000 total combo . It lacks the eye tracking of the OM-1 but otherwise is very competent. I've considered the 100-400 for greater reach but with the weight and size the "travelability" goes down. I would be lost without DXO Pure Raw 2 (Pure raw 3 is very slow on my computer and the size of the processed file is massive). I often have to shot at Iso 6400. A lot of bird action is early morning. Yes. It's hard not to compare the quality of photos on the local facebook group and wonder how they get such crisp detailed photos. But, I get enough good bird in flight shots to keep me occupied in post processing. Especially with pro capture.

[@Duade]

Thanks Kim, yes, Olympus is perfect for weight and portability, great to hear you are enjoying yours and yes DXO is very helpful. Cheers, Duade

[@rudigerwolf9626]

Between AI Noise reduction and PS/LR Lens Blur, the full frame "advantages" are quickly going away... whereas the size, weight and price make M4/3 pretty much a clear winner if you travel, walk a long way, and want weather sealed for lets say real telephoto (Camera, 600mm f/4 lens, or roughly 200-800 f/4.5 equivalent). There is no contest having used both Full Frame and M4/3. I love the fact that full frame has higher resolution. I truly miss that capability. I happily trade that for the size, weight, price advantage. The other issue I have with comparisons between M4/3 and Full Frame is the perception that F/4 on MFT = F/8 on Full Frame. Your explanation is the best I have seen. Many don't bother explaining it only applies to DOF. If I shoot in the same conditions a MFT and Full Frame camera, I use the same exposure values to get equivalent exposures. Same ISO, F-stop, shutter speed yield a well exposed image on MFT and Full Frame. Only difference is depth of field. So now let's compare: Olympus 300mm f/4 vs Sony f/4: $2,999 vs $12,998; 8.9 inches tall vs 17.7"; 3.3 lbs vs 6.7 lbs. M4/3 is 25% of the price, half the size and half the weight. I know which I would rather pay for and carry with me. And if I need to use a little post processing to increase background blur, I'm happy to spend the time. Will the Full Frame end up with slightly better image quality.. probably. Would I notice most of the time without pixel peeping... I doubt it. As I said before... wonderful, well balanced, honest video.

[@atanuhalder7750]

Depth of field is not the only difference. It's light gathering capability (noise depends on it). OM, 300mm f4, Shutter 1/500, ISO 200 is equivalent to FF 600mm f8, Shutter 1/500, ISO 800. This will produce same DOF, noise level everything. By the way , shutter speed and physical aperture (=focal length/f-stop) determines how much light is coming to a lens. 300mm f4 has a diameter of 75mm; same as 600mm f/8. MFT offers good value, 300mm f4 (aka 600mm f8) is no joke, but it is not 600mm f4. A 600mm f4 literally means physical diameter of 150mm and produces much cleaner picture with shallower DOF. If you don't want that 600mm f/8 is definitely good compromise, or even 600mm f/6.3 (nikon pf) which is a better option but expensive.

[@rudigerwolf9626]

@@atanuhalder7750 With due respect, I literally shot the Nikon 600 on a Z9 (rented) and the OM 300 on an OM-1. This was not a mathematics problem. Same shutter speed, ISO, f/4. Exposure is the same in the real world. Only difference is depth of field. Try it for yourself.

[@atanuhalder7750]

@@rudigerwolf9626 That's because the ISO is same in your experiment. As you mentioned, 300mm F4, ISO 1600 on OM-1 will have same exposure as 600mmF4, ISO 1600 on full frame, but it will be much noisier. Better comparison is 300mm F4, ISO 1600 on OM-1 and 600mmF8, ISO 6400 on full-frame which leads to same DOF, same noise, same exposure at same shutter.

[@mistergiovanni7183]

@@atanuhalder7750 But the ISO value is no longer a reference between brands, because I understand that each manufacturer puts the value they want. The ISO value was a standard at the time of the film. And on the other hand we have that the value of the F number in M43 is a nominal value, not a real value. This is a marketing move to make the lenses appear brighter than they are.

[@craigb8379]

Very interesting comparison, Duade, and well explaned. I always appreciate that you point out relative strengths and weaknesses without making claims that one is definitely superior to all the others. You rightly point out your preference for what works for you, but you don't denigrate all the others in the field. As an Olympus and now OM shooter, I agree with your assessments about some of the challenges in subject isolation and noise handling. The challenges are at their most difficult for wildlife. For almost any other genre, these are less of an issue or virtually non- existent. For me, the trade-off of weight and portability was worth it when I changed 5+ years ago from Canon crop sensor DSLR and Tamron 150-600 lens. I captured way more photos with Olympus as I carried the camera way more often. I could take a wildlife lens on a general holiday overseas with my wife where I would not have justified it previously. Were making the switch today, I don't know if I'd make the same decision now that the others all have smaller mirrorless bodies and native mirrorless lenses that are also smaller than previously. I have a lot invested in Olympus/OM so I won't be considering switching. And as you say, the capability of the OM body punches so far above its weight per $$$. I think if you shoot multi-genre, the MFT system is hard to beat. But if you are a dedicated wildlife shooter, the options are so varied. Terrific to have the options now, as you say! As an FYI, you might find the noise handling challenging on the OM-1 but it is a vast improvement compared to the previous Olympus bodies. The noise is only slightly less, but the control and type of noise is massively improved.

Fair, balanced, efficient and informative. You're style and videos are always personable, informative, and well-balanced. As you allude to, picking the right "tool" depends on your use intent. As my understanding of photography and what I like to shoot and how I like to shoot evolves, the importance of certain features in the gear take on a higher level of importance (i.e. high vs low megapixels, frame rates, weight, low light performance) and so on. The difficulty comes for those just starting out, and this video will help start that journey. As everyone likes to say, the best camera is the one you have with you. Well done, as per your usual, Duade. Keep them coming.

[@donk8292]

Duade, Thanks so much for your videos. In a world filled with biased content, your videos are a breath of fresh air! One thing you might want to explore on your OM-1 is the in-camera AF limiter settings. That one feature is what makes the OM-1 my go-to camera when it comes to BIF. My Canon cameras are always reverting to minimum focus distance when I miss getting the subject in frame against the sky. While some lenses have an AF limiter setting, it is almost always way to short a distance to be meaningful. I often am shooting birds that are no closer than 70-100 feet. The OM-1 allows you to set 4 separate AF limiter settings with both near and far distance being customizable. Makes the focus get back to the needed distance much quicker. Wish my Canons had that. Curious if Nikon or Sony cameras have anything similar. I hope you get a chance to look into that feature on your OM-1.

[@jon_green_photography]

Great video Duade. I hadn't appreciated the effects on depth of field on full frame vs crop so that was very interesting for me and excellently explained. For me I've always been an APS-C shooter due to cost. If I could afford it I would love to have full frame. But then I feel I would miss the extra reach and perhaps want longer heavier lenses....but then the low light performance would be better on the full frame....Pros and cons. In an ideal world I might have a crop and a full frame depending on the scenario. Alas I can only afford one and Im ok with that. I will always have camera and lens envy but I will never stop enjoying going out and taking photos.

Great footage as always Duade. People might not realize how the weight helps in low light shooting circumstances with MFT. I recently finished my Great Horned Owl project along with my friend where we had to photograph the parents feeding the young, and their other routines as owlets fledged from the nest before sunrise. My OM-1 with Penleica 200mm F2.8 is so easy to handle comparing if someone with FF + 400mm F2.8 lens. I took two OM-1 one with 200mm F2.8 and one with 300mm F4 and had a fantastic time without any tripod. It was much harder for my friend with his R5 with 600mm F4 lens. In most situations before sun came up, he could only manage still and not any more fast moving shots. But his image quality of course are better than mine and that is to be expected.

Quite a few well-informed folks such as yourself have highlighted the full range of pros and cons, including DOF, across these systems. Strange that manufacturers cite focal length equivalents, but not aperture equivalents when selling lenses. Great review and comparison. And to the point about being able to take great photos with any of these systems, I completely agree. But the added benefit of features like electronic shutter or eye and subject tracking or "heads-up" displays or customizable buttons on the more advanced cameras just make photography a bit easier and enjoyable for me as an older photographer. Thanks, Duade.

[@davidhuffman4768]

Hi Duade, Great video. Sensor size is always one of those topic's that many KZbinrs get way to emotional about.I shoot the OM-1 with the F4 300mm prime and I am really pleased with results. What gets lost in a lot of the discussions is that understanding the strengths and weaknesses of your chosen format is more important than the gear itself. I appreciate that you were fair in your assessment. Too many folks like to imply that Full Frame always produces a better image than a crop sensor camera. That is simply not true. What is true is that all cameras today are capable of producing great pictures if you spend time learning how to use your gear. A mediocre photographer with the Z9 is not going to produce a better image than an expert photographer with an OM-1. I'm sure if someone said Duade, "you have to shoot with M4/3 for the next six months", you would adjust how you do things to get great pictures with that format. Thank you for providing great content as always. Hope you keep the OM-1 in your arsenal.

[@guffygolfer]

Excellent. I own the OM-1 and the 300mm F 4 with a 1.4 tele convert. Works great in decent light

[@GregorMima]

Yeah as someone who has been shooting crop for ages, i always needed 1-1.5 f-stops less for DOF on crop compared to FF ... the avrg 2.8 FF zoom should be 1.8 on crop. But it never is... 😉 very good overview! Now compare lens prices ... since people always like to brag about cheaper crop lenses... 70-200 F4 on FF is about the same as 70-200 F2.8 on crop bokeh wise, but 2.8 is about twice the price. Still i really like my crop bodies 😄 Especially for macros i pref crop - where you actually want less bokeh.

[@derekgpony]

Awesome presentation! Unbiased and you nail all of the major points (pros and cons) of each sensor size. I appreciate the real-world examples of each. Nikon has really impressed with their Z cameras and lens line and if I were starting from scratch, they'd probably get my business. But, as a hobbyist, without unlimited funds, it's hard to justify changing systems. So, I stick with m43 and for FF I have an OM-2 35mm camera (doesn't get used for wildlife). Just discovered your channel and enjoying your videos.

Fantastic explanation of crop factor and the impacts in the field and/or post shooting.

[@joncothranphotography9375]

Lots of info for sure! Thanks, Duade! I'm still loving my Canon 7D ii DSLR, but I do plan on going R6 full frame to add to my kit when I can. Keep up the great work!

[@nerdyandy3101]

Good study not leaving many stones unturned. Thanks !

As a M43 user, definitely enjoyed your explanation,...you've definitely earned yourself a sub...👍

[@michaelgabes7574]

Great "objective" comparison! Thanks for that! Best comparison i've ever seen. I own the OM1 since a couple a weeks and ist just such a incredible good piece a camera! Personally as a Hobby Fotographer I see no reason too spend more money for and to carry heavier gear, knowing that DXO does such a good job in reguard of denoising. Camera and lens for far less than 4000,- $US! I'm done! But your arguments in mind, I see the point that other people will vote differently.

[@satcat]

Super informative.. very well presented too. keep up the good work.

[@brianmckeever5280]

A very rational discussion, kudos. I use OM-1/G9ii, from 16-800 FF equiv. in a small backpack that fits in an overhead on the plane. May your back support your FF preference for many years!

[@Chris_Wolfgram]

I owned the Canon R5 for a year, and shot about 100K shots with it. It was my first mirrorless and it was a really nice camera. Then I rented the R7. Loved it so much, I ordered one before i even returned the rental. Shot with it almost every day for a month. I started to feel guilty about my R5 sitting on the dresser, so i pulled it back out to give it some play. In a nutshell, I didn't enjoy it as much, but most importantly, I was not getting as many keepers with the R5. Ended up selling my R5 to buy a second R7 + the 100-400 (won't use it that much, but had to have it in case I needed to shoot something wider) + the 600 F11... But my primary lens is my beloved 800 F11 🙂👍 1280mm equivalent on my R7, and I'm finally finally getting close enough most of the time. Many of my shots of small birds nowadays need zero crop 👍

[@chrisbrown6432]

Thanks Duade. I think this is the best comparison I have ever seen . I am very grateful for it.

[@Duade]

My pleasure!

[@matthitchins4525]

Another great video Duade, really enjoying your content at the moment. Keep up the great work. I used to own the OM1 and the 100-400mm and have sold that to get the the R6 and the EF100-400 with 1.4x converter. The R6 definitely allows for better shadow recovery in images and enables better subject separation, but I must admit that I miss the OM1, especially for its light weight and features... If only I could own both!

[@Duade]

Thanks, will do!

[@dionhouston]

Really great video. You covered the difference between the sensors very neutrally, which definitely isn't normal on this topic :). The main thing I wish we (photographers) could get away from is the word "crop." That a 35mm sensor is "full frame" is really an arbitrary distinction - certainly back in the film days, 35mm wasn't considered that. I get why people do it - as you mentioned, _relative to a 35mm sensor_ these sensors cover a smaller area, but they're designed that way -- nothing is chopped off. If you look at the equivalent megapixels by area that often really tells the story. My FF Pentax K-1 for example, is 36MP, my E-M1.2 covers 1/4 the area at 20MP, that's more than double the resolution...

[@Duade]

Thanks Dion, yes, I agree and even I get confused, I got the image circle wrong and yes the Olympus and Fuji sensors are purpose built that size and not a crop and the lenses are designed to fit, I will be sure to mention this in the review. Cheers, Duade

[@dionhouston]

@@Duade You are really awesome! Frankly, "crop" is the accepted term, so you're not faulted for using it, but there's no doubt it's led to a misperception that M43 is somehow inferior to FF. With all sensors, the biggest challenger we face is physics. Low light performance of M43 is generally worse than that of larger sensors, but that's mostly a function of pixel size. FF hits the challenge that aperture size is a function of the focal length and the size of the opening, so lower f/stop requires bigger equipment. No way around either of those. You hit absolutely perfectly the point, though - I don't think anyone in our community would say that M43 is objectively "better" than FF. Just that it takes great pictures, for a package that's much smaller and lighter. No wrong answers on sensor size - it's whatever you need to get the shots you want... Thanks again for the awesome review...

[@nineoneten]

Hello Duade. Love the channel - up there with the best of them..... I was under the impression that one of the techniques to use for subject isolation was to allow the camera to autofocus on the bird and then tweak the 'in-focus' area using the full time manual overide that lenses have had since USM/AF-S etc have been available. That allows you to pull the 'in focus' area towards the camera which in turn increases the fall off behind the subject and gives the subject more isolation against the background. Maybe the clever people at Olympus could even have this done by the camera ? Assign a button to move the focus point back towards the camera. Cheers - Rob in the UK. ( We could now have a long discussion about CoC and how sharp the image actually is either side of the main focus point.....!!

[@brucegraner5901]

Great video. Thanks for giving some attention to cropped frame options, especially MFT. I shot full-frame professionally for newspaper work for over 40 years but, upon retirement, found myself with just two personal cameras, a Canon SX60hs and a Leica V-Lux 114 (one-inch sensor). But I was surprised at what I could achieve for birding with these images even when enlarged over 16x20". My "big" sensor camera is now the Lumix G9 and 100-400mm lens which has offered things like pro-capture and 20fps years ahead of big name full-frame cameras. I admire the subject isolation of full-frame gear but I really enjoy photo hikes with my light MFT kit. I still bring the SX60 with me from time to time because it can reach out to the 35mm equivalent of 2,000mm's. No if I can only get a G9(Mark2) with an Ai, creamy background digital filter:) I look forward to all your videos.

[@malcolmmeddings8502]

Thanks Duade for your great explanations ! My own experience with different sensor sizes largely mirrors your own. I now shoot with Olympus - EM-D M1 mkiii and in the last two weeks added the M1x , which replaces the EM-D M1 mkii. My old Canon 1Dx outperformed my old 7D mkii and the Olympus models, but the Olympus and 7D mkii I find almost indistinguishable. Maybe the 7D mkii is very slightly less noisy. The big difference is weight. The 1Dx and Canon 100-400 mkii weighed in at over 3 1/4 kilos, the 7D mkii and the 100-400 mkii at over 2 1/2 kilos, whilst the OM-D mkiii and my Panasonic 200 2.8 comes in at under 2 kilos. Being able to shoot at 2.8 gives me a similar D of F to the full frame with sensible ISO, which reduces (but not eliminates) the noise increase with MFT. Compared with the 7D mkii, it is an improvement noise wise. Weight was the reason for the switch to MFT. Yes I'd like to shoot full frame, but can't afford the bills for having my back seen to every week! Incidentally my main photography is shooting motorsports and birds - static and especially in flight.

[@callline7183]

Great no nonsense review, as always. Great summary. Keep up the good work.

[@johnclark9499]

Hi Duade. Yet another great video, thank you. Really helps explain the pluses and minuses of the different formats. The size (and weight) of the M4/3 kit is really impressive and tempting. I seem to end up shooting at high-ish ISO settings in order to get a high enough shutter speed (can't afford or want to carry around a massive 500 F4 lens) for bird/wildlife photography so the larger the sensor the better for me. Also prefer the control of DOF with full frame. Having said that I just spent 6 weeks down under in your part of the world and you certainly have better/more light than we do up here in the North of the UK (well I'm sure the sun doesn't always shine down there but you know what I mean!). While we were down under we were with a friend who uses Olympus kit and he certainly seemed to do as well as I did with my R7 and RF 100-400. Thanks again.

[@Duade]

Thanks John, yes, light can always be an issue, the Olympus 300 f4 is nice as you get f4 which lets in a lot of light. Yes, very lucky to get the light we do down here, cracking few days lately. I am sure you have many wonderful photos from the trip. Cheers, Duade

[@briandurell]

Thanks, Duade, for this thorough and balanced comparison of cropped and full-frame sensors. It gets very complicated because while you can illustrate the effects of the size of the sensors, megapixel counts vary so much between camera bodies and that, of course, impinges on how useful it may or may not be to crop in on images. Usually, cameras with full-frame sensors will offer more megapixels. That said, you have given a very helpful presentation. Greetings from Canada.

[@blisteringbooks2428]

Once again a brilliant video, even though I was aware of all the info already. The trouble with manufacturers tempting us with ever more elaborate kit is we can become overwhelmed. I bought an R5 to get more MP and found that most images were unusable with my Sigma 120-300, so I can only use that on my R6 or 5D4. The images on my 7D2 are horrendously noisy, only now usable because of Topaz, and I was wondering about an R7 for the reach. Only we don't always have to clamour for MP, using the R5 in crop mode I get the same field of view, just 17MP instead of 32MP, and do we actually need 32, especially with current resizing software. Some OM1 users have told me it isn't good if you crop heavily, not enough clarity. I was thinking about doing a video on crop sensors, that too many pixels can make the image soft, the sensor is out resolving the lens, only the difference isn't that obvious on KZbin quality. It would help if I wasn't on a pension, only I have far too much kit already. Once again, excellent quality video, keep up the good work.

[@klaustomasini]

Thx Duade, as you know, I am a OM-1 / E-M1X shooter. Amazing feature of OM System / Olympus is the ProCapture mode. Thats an insane feature ... Tomorrow I will get my OM System M.Zuiko Digital ED 90mm F3.5 Macro IS PRO lense. Weekend is scheduled for testing.

[@Duade]

Congrats Klaus, I look forward to using the OM1 in the coming months, good luck with the lens. Cheers, Duade

[@michaelhains2291]

Duade If you are using a 30mm, 45mm or 60mm macro lens on the Olympus OM-1, get a flash diffuser. It takes your macro images to the next level. The Cygnustech diffuser is a great option (Melbourne based,). I also have the AK Diffuser from the US. The Cygnustech is worth every cent. For me, M4/3 is my go to macro rig. I use a Godox V350o mounted on the flash shoe, which has the Lithium battery.

[@buggersofoz]

So great that you now have 4 systems to compare and so well balanced video. The only addition, which you covered in an earlier video would have been a picture of the galah taken with R5 and 300mm prime lens and OM-1 300mm and then cropped to shot the IQ difference, not ISO performance. I guess at lower ISOs there would be no difference. Personally I moved from 7D2 and not so sharp Tamron 18-400mm lens (A$1600 second hand) to an E-M1 and 75-300mm (A$600!). But many friends don't trust second hand gear and they are all going with an R7 and RF 100-400mm, which is probably the sweet spot for birds, as nicely showcased on your price comparison! Glorious video!

[@jindrichpavelka]

Thanks for another pleasant video! Will there be a seperate in the field video (my favorite type of your videos 😁) about using the OM system? I'm most curious about the lens, cause 200-800 sounds pretty dope and I as a Sony full frame user would love to try take some photos with this OM lens.

[@tapere7277]

Very interesting, thanks so much for this. I have just got an OM-1 and 400mm lens, having used Canon full frame for years. The weight is the big factor for me - I just shot some gulls in flight in Anderson Park, Napier and there is no way I could have done it with my Sigma 150-600mm lens on the Canon. I like to walk around and the OM-1 is just a dream - the stabilisation is out of this world and the AF/AI tracking is sensational. I also prefer to have some habitat in my shots so the DOF is not such an issue for me. I also enjoy the challenge of having to get in the right position without spooking the subject. But as you say it is a matter of personal choice and there is no right or wrong - whatever works for the individual. Maybe as you get older you will move towards lighter gear haha...

[@Ricky9Toes]

Hello there just wondering if u are using the 100-400 f5.0 to 6.3? I use it with an em5 mk3 and sometimes have issues with the stabilisation, although when taking enough photos I still get them sharp. Just wondering the difference with the om-1 and the em5

[@tapere7277]

@@Ricky9Toes Hi, I have the Panasonic Leica DG Vario Elmar f4.0 - 6.3 100-400 ASPH which I got based on reviews and also it's size and weight. It is smaller and lighter than the equivalent Olympus lens I saw. This is my first Olympus/OM-Systems camera so I cannot comment on the EM5. What I can say is that the lens and camera are very, very sharp, the autofocus and AI subject recognition are extremely impressive and the stabilisation is great (6.5 stops). I can hand hold at 400mm for hours no problem.

My favorite aspect of APSC mirrorless coming from a person with a huge collection of DSLR lenses is the versatility given by the extra flange distance. You can use drop in filter adapters, focal reducers, tilt shift adapters, etc with older lenses. That 400 5.6 is a 450 f4 on the r7 with a .7 focal reducer, and weighs almost nothing comparatively.

[@The-Secret-Dragon]

I've never heard of a focal reducer before!

[@johandeprins5448]

Nice and honest comparison between systems! As an olympus user for many years I happy with te results portability & price wise I can afford myself more compared to fullframe system and the size assures that I have my camera with me on every hike whithout hurting my back... Mostly 300F4 mm and 12-100F4 also 1,4 teleconverter works superb with the 300mm. The 100-400 is in my opinion not the right choice if you are "serious" in wildlife.... to much of a compromise of everything price / range / aperture & stabilisation ( 100-400 does not work together with bodystabilisation -- 300mm or 150-400F4,5 do so) I enjoy your content, so continue! Grtz

[@MotoRich900]

For years the selling point of full frame was the pleasing shallow depth of field for portrait, personally I sometimes see this as a handicap for birding, where the eye of the bird is sharp but the tip of the tail is out of focus, another benefit of the M4/3 is the pixel density so more pixels on the subject, compact lighter and sharper lenses, plus the OM-1 is IP53 rated as are the lenses none of the other more expensive bodies have the same weather sealing and toughness as the OM-1.

[@Duade]

Thanks, yes, the OM1 package is very nice and I am glad I purchased the camera, I think I need the 300 f4 to really enjoy it. Thanks for the comment, Cheers, Duade

[@12symmo]

Pixel density of m43 and the r7 are the same. The difference is the overall size of the APSc sensor will record more light. Of course if you find yourself always cropping the r7 down to 20mp, then the extra surface area of APSc is irrelevant and you may as well be shooting m43, other things being equal.

Hi Duade, thanks for another very informative video. I'm still using my trusty 7D & 90D & had put money aside to to purchase a R6 mk II but saw a "opened/unused" immaculate Canon 100-400 IS USM mk II for sale. I bought it for just under half the recommended price & the difference in photo quality has been really quite surprising, I thought my existing lenses were quite good but the canon 100-400 mk II has been fantastic. I still intend to to get the R6 mk II when funds are available but just proves what you have been preaching about getting quality lenses. When you talking about the noise reduction software available I was wondering if there will be software in the future that will effectivly blur the background in photos, maybe there is now but I haven't heard of any. Anyhow thanks again for a great video mate. Cheers George

[@Duade]

Thanks George, congrats on the lens, I too was surprised by its quality and the IS, MFD, sharpness etc are all just fantastic. Yes, software is getting better, I think they are close to getting the DOF done. Just a matter of time. Cheers, Duade

[@holgershund]

Nice to hear about M4/3. I'm a user of Olympus OM-1 and 300mm f4 - and sometimes to carry around Lumix 100-300mm 5,6 II. On the little island (Als) where I live in DK, there are several nice areas with birds - even a few with many migratory birds. However it is rather difficult to get really close at the birds (water, mud and legal restrictions). All in all M4/3 is a good compromise on weight and price for me. Olympus is a lot cheaper as you state. Your channel is of very great value for me even if you do prefer full frame! Thank you 😊

Thank you for the video, very balanced commentary. I use an OM-5 for general photography and it is awesome: very light and feature rich for the price. One benefit of MFT, which your genre would not teach you, are vintage lenses. With the right adaptors, a world of full frame vintage lenses are available for MFT cameras. Importantly, the MFT sensor suits right in the centre of the full frame lens, giving you the very best of the resolution of that lens. Really gives your photography a new dimension and very budget friendly 😂. Thanks for your video, much appreciated.

Beautiful image of the Red-kneed Dotterel, stunning actually, it blew me away. Learning a lot from your conversation with D Cooper (will check back in as it's ongoing). We are going to purchase either another R5 or the R6II. Waiting to see if a decent firmware update will be forthcoming for the R5. Have watched your reviews of course. What say you Duade? Really value your opinion. (Only if you have time.)

[@Duade]

Hi Joan, yes, that image spoke to me also and happy I managed it. The R5 is a tricky one as the rumours suggest a replacement early next year but who knows with these things. The R6II is a beautiful camera but lacks the reach of the 45mp of the R5. So, it really depends on the lens you are using with it. I don't think Canon will offer anything crazy in terms of firmware for the R5. For pure birding today I think the R5 is the better option however I might be tempted to wait for the R5II as I believe that will be a very impressive camera. Cheers, Duade
