[@pweb4941]

watching with interest

[@pweb4941]

max thanks for the test. This is really upsetting

[@jakelindsay6251]

Keep keeping it real, Max. Results don't lie. Very surprised with these results. My G85 seems like it does better. And my EM1 ii definitely does better...and my X-T2 does better than all of those!

[@Holtenstein]

Max Yuryev I still bought it. I would like to know if this is an improvement over the Gh4's AF system. For me, I have a lot of FF Nikon glass already. If anything this makes me question buying native m43 glass. Not the GH5. Thanks for the hard work!

[@cooloox]

Jake Lindsay Well that really says something because X-T2s hunt a lot and are fairly poor at video AF.

[@ArthurR]

Yea, that is bad. The fast/accurate autofocus is why I like Sony so much.

[@nemethmik]

Yes. No way reliable continuous video AF can be implemented without phase detection technology, and today only Canon and Sony has the technology. Panasonic was crazy not asking Sony to make PDAF into this m43 sensor, it would have been a killer. The A6500 kills this GH5 any moment in a number of arenas.

[@MaksimYuryev]

I'm pretty sure Sony makes the 20.4MP Olympus E-M1 mark II sensor and it has phase detection where the Sony 20.3MP sensor in the GH5 doesn't have it. It seems to be Panasonic's choice. Sony even makes the Samsung Galaxy S7 "Dual Pixel" sensor.

[@TonyAndChelsea]

Max! Thanks SO much for making this! We just got our GH5 and we're trying to figure out how to get the most out of it. We'll definitely give you a shout out. It seems like the AF points are actually wider than it shows on the screen, and if it can find something in focus outside of the specified AF points, it'll be satisfied and not hunt for focus. Perhaps using even fewer AF points, or a smaller AF point, would help it find new subjects?

[@russoch2186]

That's exactly what I think

[@MaksimYuryev]

Tony & Chelsea Northrup No problem thanks for watching! If you guys have any input I'd love to hear it. I'm currently speaking to Panasonic about it. It does seem like the it is reading wider than it displays. Single point works better but for any sort of tracking or movement single point is hard to use unless you can be very predictable with it like in our test setup inside. We will have another video out tomorrow comparing to a6500 and with one of the tests we had to set to single because wide or zone would not pick up the subject even though it was clearly dominant and in the center of frame.

[@UraFlight]

Tony & Chelsea Northrup Two weeks ago at Photoshow Panasonic could not gave me an answer about slow AF on GH5. I was very disappointed with this model

[@AANasseh]

The AF is not slow. It's super fast. You just have to half press the shutter button and it catches focus super fast. The press all the way and it records. And turn the continuous AF off! It should be AF Single. Who needs the focus to change and for the camera to keep track during recording. You focus and begin recording. That's AF, not continuous AF! If you want the camera to pull focus for you use Focus Transitions!

[@MaksimYuryev]

I hope my previous comment explains some use cases where continuous is very useful. (if the system works well)

[@DaveDugdaleColorado]

Thanks for all the time running the tests. For those that require AF, the GH5 might be a frustrating camera to use.

[@MaksimYuryev]

Thanks for watching Dave. This was supposed to be a 10min video but I kept having to do more testing.

[@kokoronai594]

Agreed, which is a shame because in virtually EVERY other aspect it's pretty much unbeatable at this price point.

[@BasementBrandon]

Max, appreciate the time and effort this took... especially considering the quick turn around time addressing the comments from the last video.

[@MaksimYuryev]

For those wondering how it compares to a6500, check out my latest video here: kzbin.info/www/bejne/d3bWhKaaibB9qZY

[@findbinnu]

Reading the comments on your channel is like dealing with grief counselling: first there is denial (it can't be that bad, so and so is getting great results!), then anger (you did it wrong), then bargaining (can you recheck, is yours a bad copy, can firmware fix it), then depression (man, I was hoping this would replace my old cam), and lastly, acceptance (guess Sony/Canon is better).

[@videograph]

Great series of tests! Best on YT at my opinion. Made a link to your channel at my last video. Keep it going!

[@LeeZavitz]

SO much work man. Thanks for making this video. I appreciate it. I'm hoping to get my GH5 soon. Looks like I'm keeping my A6300 for AF on the gimbal.

[@MaksimYuryev]

I will as well! We shot some comparisons with the a6500 (same af as a6300) should be a quick video that we will post tomorrow or the next day.

[@LeeZavitz]

Its the only reason why I have kept the a6300. I use it to shoot all my yt videos. You just set it up and it tracks AF like you want it to. Overheating aside its been way more reliable than my A7Rii ever was. But I still want that GH5. 4k 60fps, battery life, low rolling shutter, and no overheating! The a6300 and GH5 will be a good combo with some speed boosters and share same Canon glass for MF and then keep the Sony 10-18 on the RoninM for AF. Anyway thanks again for the test. I know how much work goes into it.

[@PostColorGear]

The 6300 is a monster of a camera. I recently sold mine, and now I have an olympus because the IBIS is literally second to none. But there is NO beating the 4k quality and phase detect autofocus on the Sony A6xx series in that price point. I may just buy another one.

[@poman911]

You can eliminate the overheating by putting it on a cage. Battery life with an external battery set up that Max had shown. There is a hack to get rid of the 30 minute limit. Rolling shitter ... I pan very slowly and then speed it up during edit. Everyone is blown away everytime they see my a6300 video in the 4K 24fps mode.

[@adrianpocea2287]

The Post Color Blog Monster my ass...It is a mediocre body with terrible controls, horrible without ibis, jittery at the smallest shake, terrible, invisible in daylight screen, impossible menus, bad ergonomics, you name it. It has indeed a very good sensor, but the lens selection is beyond par...

[@Golfholics]

I was thinking of getting his camera but after your test I'll stick with my Leica SL and Leica Q. What camera can do 4K at 120fps at 8 or 10 bit other then the REDs? We do golf videos and having a slow motion swing in 4K would be amazing. 1080P at 120fps is just not cutting it.

[@gfranks007]

I really appreciate all the work you put in to create this. Very useful!

[@BartJohnsonProd]

Hey Max, quick question about your tripod plate adapter. Is that the Manfrotto 357 adapter? If so, what short plate are you using? I use the 357 adapters as well, but they always come with the long plate.

[@df0rce]

Finally, an awesome GH5 in depth AF test video. Many kudos to you!

[@simba673]

Thanks so much for making this. Excellent work!

[@0rtmasta]

Great in-depth work Max! Thank you!

[@charles9glenn]

Thank you so much Max for in- depth testing and you make everything clear about this product.

[@daneparsons4922]

Thanks for your hard work and information Max, keep up the good work.

[@g0at3]

Ok , I got my GH5 in last night and I am confused. How do I get the camera to keep focusing when I am hands free (for gimbal work). I can only get it to initiate the focusing with the AF-ON button (reprogrammed) or the half shutter press.

[@biscuitsalive]

What sort of lights were you using inside? (Frequency) Would that have a effect on AF? Just a thought.

[@loudpanzer]

who's like you're the only one a covering autofocus so detailed. I really appreciate it you save me a lot of hassle.

[@MikeBrayton]

lots of time spent on this. thanks!

[@jcristina]

Great video Max. I'm looking forward to your calibration with PhotoJoseph. I'm wondering what you think about the restructuring happening at Panasonic? Digital Imaging Division is said to be moved to the Appliances Division? Cameras and Microwaves under one umbrella?

[@Rielestkid]

This is an exhaustive test for just AF! Damn man, good job.

[@justjannes]

very good review. Thanks for your work and effort. I like the way you are doing this review. Not just showing some video but explaining what you are doing. Great work!

[@Ninetou69]

It seems like it may be because of a poor matching of sensor resolution and slow DSP from Panasonic and the fact that they rely on Contrast AF system. In contrast AF systems, DSP (Digital Signal Processor) has to scan every frame of an image vertically and horizontally to detect edges of visible objects and adjust it's focus until edges become the smallest (sharpest). This process happens on every frame of an image and the bigger the image resolution the more time it takes (a process that generally shouldn't be parallelised because dividing image into smaller chunks negatively affects edge detection algorithm) hence requiring a very fast DSP chip in order to be able to do so effectively. Also the higher the frame rate the more edge data it can gather and the faster in can focus. I'd love to be wrong here but your findings with zone focusing being the most reliable only confirm that. In zone focusing mode, the DSP scans selected area of an image significantly reducing amount of lines it has to go through to detect edges. Sometimes only basic edge detection is applied outside that area but that depends on manufacturer's implementation. The fact that it rack focus so poorly in that mode would suggest a software issue and adjusting area weighting in future firmwares could improve that. Also notice that AF performance was generally good whenever your assistant went out of the frame so that only the door with its strong pattern was left. The more distinct the pattern the easier it is to focus using contrast detection. I suppose you could try testing its AF on various surfaces to investigate this behaviour further if you'd have time but I think results will be close to what I'm talking about. Good video Max. You do a lot of in-depth testing, results of which can show technical limitations of various bodies especially to someone who understands underlying digital signal processing techniques. You're my go to guy for camera reviews.

[@MaksimYuryev]

Great insights! This makes total sense! People thumbs up this comment so everyone can understand this. Thank's Ninetou!

[@Ronbc000]

Max. Thank you for your effort and honesty.

[@seanconley]

Thank you so much for taking the time to do these AF tests so we don't have to. Mad respect.

[@SkeletonStewdios]

Thanks so much for all this testing! After watching this and your previous video, I am wondering if there is something wrong with the camera body. It almost seems like they would have to be insane to release a camera with that bad of focus issues.

[@armwrestler0128]

Thank you for the time your have dedicated to GH5. Much appreciated!

[@caveran16]

whats better a7s2 or the gh5 looking to buy a camera to use for music videos and short films . I am an editor but camera guy left to do his own business he had a gh4 and a7s2 i am looking to buy one of them. what is the best lens he used a speed booster for his cameras. Im not sure which lens to buy please help me out !

[@andrejgrznar]

thanks Max, fab work!

[@thinklearndesign7441]

Nice videos. I have the gh5 with Leica Nocticron lens. I can't seem to find a way to "half press shutter button auto focus" while in movie mode. The dial is on the video camera symbol with "M" beside it. Is it even possible to focus like this?

[@phcib2195]

Great Review,,,,Do You think You might have got a bad copy or if all the cameras do that maybe a firmware update could correct the problem ?

[@quickpickle]

my dream camera... focus system of the canon 80d. low light and dynamic range of the a7s2. battery life of the gh4. features of the gh5.

[@zurih]

This is really appreciated Max, I really think you're one of the best if not the best reviewer on KZbin. A huge huge thumbs up for you.

[@PostColorGear]

Max, that test at 19:22, do you think it was the lock on option that caused it to "lock on" the car? I agree with you that it is weird that even if you change the focus point that it doesn't respond to that. Good for staying locked on a subject I guess, but bad for focus pulls.

[@jmhunter83]

Great video max... very interesting.

[@GiulioSciorio]

Hi Max. Did you have the camera switched to Continuous AF on the back of the camera and within the menu?

[@MaksimYuryev]

Oh definitely!

[@sammyb7134]

Did you do anything to set up this lens in your camera so that the aperture is constant? Mine is jumping in a bizzare way. Also I subscribed to your channel. I love your vids!

[@NaturalGallantBodybuilding]

Great job on your work on this video. I've been using the Mark IV for my video work, and it has been pretty great. Have to love the video quality of the GH5, but what's the point if you're not in focus? :)

[@gteague]

there's a hugely long dpreview thread on the subject despite 99% of them never having seen the gh5. and i've read pages and pages of stuff and watched hours of video and yet i've never heard a single person quote this from the advanced manual: "To ensure highly accurate focus, 4K motion pictures are recorded at reduced Auto Focus speeds. It may be difficult to focus on the subject with Auto Focus, but this is not a malfunction."

[@ovidiudan1641]

Isn't that kind of a contradiction? It's like saying ... to ensure good focus in 4K, we're going to give you worse focus when you focus on a subject. Also, Max found 4K 60fps has the fastest focus (same as or slightly faster than 1080p 60fps).

[@MaksimYuryev]

THIS!

[@MaksimYuryev]

I'm getting a different GH5 to test tomorrow. We shall see.

[@Elmex_1]

My fear is that they're running out of bandwidth or processing power. They could be doing many calculations (algorithms) to get the contrast detection work, and running it on 4k might be too much.

[@zvxcvxcz]

+Tuze It is processing power, because they cheaped out where Samsung didn't on the NX1 and where Sony was foolish with their overheating.

[@dpourkesali]

Appreciate your thorough review. Given that using two different lenses did not yield different results, is it fair to assume (or hope) that Panasonic may be able address this via firmware update?

[@jaffarbh]

Great and honest review. Thanks Max

[@vincentoliver]

I have not read all the posts here so forgive me if I am repeating things already mentioned. For pro video work we never rely on auto : focus, exposure, white balance, gain, aperture, shutter speed or auto audio. This may not be helpful for photographers who have become accustomed to auto everything, but there is nothing worse than a camera hunting for focus or adjusting exposure whilst action is in progress. Having said that, thank you for producing a very informative review.

[@vedranart]

Is GH4 right tool for long live streaming sessions in a studio? Let's say over 8h in full HD or even in 4K later on? Thanks! :)

[@jarrettttttt]

Great work, extremely helpful, thank you

[@aaronleung7902]

Thanks for the video and the effort in creating this video. I was hoping it be outstanding, but unfortunately not. How would you compare the AF between the GH5 and the old NX1?

[@MaksimYuryev]

Aaron Leung The NX1's are just as good as the newest best Sony's and Canons. I still have and use 3X NX1's actually.

[@AndysCuts]

nice video. amazing.. Have you test out the new firmware? Anything better?

[@markkay6369]

Thank You for your hard work Max! This just gave me more reasons to wait for the a7s III to pair with my a6500

[@LateCityLight]

very informative break down. great video

[@MrTBMedia]

Thanks for your time to make this video(tests)

[@AbishakeRakthey]

Hi Max, How good is the photography autofocus performance(GH5+metabones+ef lens)????

[@Rohol64]

Thanks for making this video. Very useful !!! Greetings from Bergamo Italy

[@elchavinha14]

great job man! not a lot of people put that much work into their videos!

[@thomaswhudson]

Is this something where Panasonic can put out a firmware patch to improve or fix this? Seems pretty unusable at the moment.

[@formattester6]

great test! I've seen a few videos like this that shows the GH5 AF not great. at times it works but randomly at times doesn't. thanks for the test.

[@GivesAMinute]

Good solid info here, particularly for us vloggers! I will say (without owning one yet) the autofocus issues are ruining what is otherwise the ultimate vlogging camera :( Is this an issue that could possibly be fixed with a firmware update do you think?

[@RogerKeith74]

You do excellent testing. Love your videos. thanks

[@knoptop]

Thanks for sharing this! Would be curious to see G85 Auto Focus compared to GH5 if you're planning some comparisons.

[@mariosubasic.media1]

nice work man

[@charbax]

Thanks for doing this video. The kind of testing I think is most relevant is the one you are doing at 15:04, handheld pointing and following your actor. That's where I hope Locked on will stay locked on well when moving walking around. I try to understand how +3 responsive is more responsive, though the mode that I was thinking might eliminate focus hunting would be Locked on face/object and then quick responsive change autofocus only when clicking on the screen again if for example to track something else. In your test it seems you mostly just set region point(s) and let it try to detect and auto focus by itself? Hopefully they can bring up all the framerate modes to same autofocus performance as for 4K60p with a firmware update? hopefully this can be improved. To be honest I've posted hundreds (maybe thousands) of videos filmed with GH3 on my channel in 2013-2015 that often had bad auto-focus performance (hunting, loosing focus, focusing on background, etc..), I skipped GH4, I was hoping GH5 improves autofocus by a lot.

[@frogchaser]

I wonder if panasonic is watching this and shaking their heads at how much they fucked up

[@eksmaan]

The GH5 is awesome. The Sony stuff is awesome. Fuji stuff is awesome. Nikon stuff is awesome. Canon stuff is awesome. They all work but you have to work it. The camera just came out. It's SICK. Thanks for quickly revisiting the test man. Tons of work.

[@ffmedia8542]

Did you activate quick AF? It looks like it wasn't. It's essential for video autofocus on the gh5.

[@UraFlight]

Great review MAX ! I'm appreciate your work. Thank you very much for your efforts and saving my time and money.I had a big doubt about this camera at Photoshow two weeks ago. AF is very important for my work . From now I started saving money for Canon 1DX mark 2

[@kdh0413]

Max, I really appreciate your time and effort. Now I really agree with your thoughts. Thanks ;)

[@jamesbiesty260]

Max thanks for this! Your review helped me dial in the auto focus settings to where the GH5 won't continuously hunt to the background and foreground when filming a simple review where I'm standing in the same place. It makes my reviews much easier to film without having to use MF with the Image app. Now I can just use a shutter release remote and let it focus so I don't have extra work. Very much appreciated. Keep being you and doing what you do!

[@YannickKhong]

Hey! Did you disable IBIS too?

[@justcurious10]

Pani will take notice. Great work. Wonder if this is a batch issue? So the XT2 is the king of mirrorless?

[@NewbArchitect]

I don't understand after how many years Panasonic has not updated firmware to fix this? Did they have any idea it's a huge issue, not to mention consumer deal breaker? I really wanted to get this...

[@djmphoto]

Thanks for doing this, I really appreciate it! It's awesome that you did this and was so painful watching the focus not change. I hope they can address this in firmware.

[@2hard2xplain]

Totally appreciated by the amount of work you've put in there. Never have my hope up about the af from the start and I'm still getting one.

[@nessc.2487]

I've been looking to buy a new camera that shoots in 4k. I'm leaning towards fuji xt2, but the problem is that it doesn't shoot shoot in frame 😕

[@mutovkin]

Max, wow this is the best review of the camera focusing subsystem ever. Thanks a lot. I wish out of 100s of "reviewers" for mobile phones or other equipment at least one would have been as thorough as you are. Most dumbos just unbox, use one of the adjectives recommended by the manufacturer to describe the device and run the same benchmark 1000s of websites already posted, give their recommended glowing comments at the end and switch to another device. With that in mind you deserve to be in a the hall of fame of KZbin reviewers.

[@bikenart]

Max, I'm wondering if a given person can do a better job using manual focus, either using the viewfinder and the LCD screen in the test, and also using focus peaking to help out. Could you do a test where you also test that please? Thanks man, nice job!

[@JonPais]

There are still a lot of naysayers, but this is the most comprehensive test I've seen of AF-C with the GH5 so far, I don't expect to see better, how many are going to spend ten hours just testing one aspect of a camera online? None! Anyhow, I've become a Patreon supporter. Thanks so much for your great work, Max.

[@FatCatAlleyMinute]

Appreciate all the hard work you did in these tests. Thank you! I personally, don't use AF, so not a big deal for me. I still love my GH5.

[@TheRadChannel]

Can you please compare to the a6500?

[@MaksimYuryev]

Check my latest video!

[@sgeorgiev]

excellent work. I am in dilemma between gh5 and 5d mark iv. is it possible to make an AF video comparison between these two?

[@PromoMoviescomau]

My advice - get the 5D4.

[@sgeorgiev]

two things are bothering me on 5D4 - the AA filter and the Motion Jpeg

[@IslandFilmMaker]

Thx Max, you delivered, and did a great job. I was one of the one's who asked for you to redo your tests! Wow did you ever! I can see that there's NO question that the GH5 AF sucks! I haven't received mine yet from B&H so I can only go by what people have put out there on KZbin. This was very disappointing but the truth must be told. Looks like I could be sending mine back if this is the case :'(

[@aandjo]

Good extensive test!

[@truecuckoo]

I think it makes sense that 60 frames instead of 24 is performing better. I guess it probably means two things: 1. It gets more data per second to analyze. 2. The 60p frame data has smaller incremental changes than in 24p, so it's probably easier to catch movement when changes are small? The Fujis also show this behaviour.

[@KenTanis]

Thanks so much for tearing into this with so much depth, Max. I know Panasonic has big plans for the upcoming firmware updates. Maybe they'll do some work on the AF.

[@aNG_HAM]

Where did you get your Apple Watch band? Great video, by the way! Very informative!

[@RideWithRahulOfficial]

I use the default mode and shoot at 1080 60 on my Lumix Fz1000 and the video autofocus works like a charm.

[@RK1FX]

just dropped by to leave a like, have a grest day Max.

[@wallstreetoneil]

wow - you may have just single handedly killed this camera - i was thinking of getting this for my v-logging daughter - this thing is brutal - thanks for this AMAZING review!

[@learningcameras]

It's been much worse than I expected. Seeing the same results as you. Point to point is good but continuous is horrible. Really nice tests Max

[@MaksimYuryev]

Yes point to point is very good. The GH4 was the same, I used manual focus with the touch AF to set focus all the time! Thanks for confirming this Dan.

[@MakersLog]

Thanks for putting in all the hard work Max. I was hoping that the GH5 would be my NX1 replacement. I think that without better AF I'll have to do some more thinking, I do a bunch of my work on a steadicam.

[@MaksimYuryev]

I was hoping to as well. I still have 3 NX1's that I use along with Sony.

[@Christian-lt9qr]

Does anyone with a GH5 know how to get it to autofocus before recording? I have it set to AFC with continuous AF turned on but it won't autofocus until I hit the record button. Thanks in advance!

[@EzzenzDK]

Hi Max Have you triad your gimbal with the GH5, and you like it?

[@MaksimYuryev]

I have shots in my first look video review but most were focusing on background.

[@mountainhobo]

Outstanding effort, thanks, Max! My conclusion: Canon should ritually set itself on fire for not taking advantage of its dual-pixel AF. If they put 4K, IBIS, proper auto-ISO, and decent codec into M5 (and most of it is sitting on their shelves), they would wipe the floor with competition.

[@IanAtkinsCinema]

Thank you sharing. I have always used autofocus as a guide to get me started where I want to be before popping it into manual and using peaking. That being said, I use autofocus a lot for processionals during weddings. I have been excited to be able to shoot processionals at 4K60fps with autofocus so I preordered the GH5 the day it was possible to do so. I have been experimenting with the "processional" situation to find a setting that works well since that is the single most common situation when I will use it. The rest of the time I'm using the camera, I won't care about autofocus. I used the Olympus 75mm wide open at 1.8 and just bumped up SS. I had my son walk up and down the sidewalk both with and without a friend behind him in order to imitate both a bridal party procession and the bride by herself. I had him walk in shade with a sunny background that was very contrasty. What I have found is that the the AF Mode with a zoned auto focus area works better than face detection, target, or 225 point area. I have also found that AF speed is working great all the way at max (5). I have sensitivity at 0 and have found some pulsing, but very minimal. I may tweak the speed and sensitivity, but right now I am happy with these settings since i didn't see much hunting and was able to follow him sharply for the nearly 30 foot procession at a fast pace. Would love to know if anyone else has done a similar test and what results you found work well for the same situation/use.

[@sam_yang]

Max, could you do AF test with the 12-60mm? I've been told by some that the AF varies from lens to lens.

[@MaksimYuryev]

+OperatorSJY We did in our first video ($999 12-60 F2.8-F4 Leica) It seemed to do worse than our 12-35 2.8 and about on par with the 45mm 1.8 Olympus. Because of this we used the 12-35 2.8 in the video your commenting on.

Thanks for the quick reply. This camera seems to have the almost all of the figures I'm looking for. Just not sure how I'm going to like it if I'm going to vlog in an uncontrolled environment - I'm scared that the camera will do a lot of hunting and mess up the focus when I'm talking to the camera while walking down streets, airports, in cars, etc. I think in a controlled environment, once you have it on focus, you can just switch it to manual and you are good to go. But in uncontrolled environment, I'm not so sure.

Thanks for this! Could autofocus be fixed through a firmware update or will we have to wait for the GH6? Trying to decide whether to switch from my 70D now or wait.

SolMate if you are considering GH5, better for all the features other than AF. It's so much better than the 70D in almost every regard.

[@MattSolnick]

True, I'll probably end up getting it! It's just not super urgent. I COULD wait but I'm too excited to upgrade :)

Max you are the best camera reviewer on KZbin - and I am not accusing you of bias or bad testing procedures. I will do a test for KZbin this weekend at your suggested using 2.8 and post the results on KZbin Monday on my daughter's KZbin channel (I will link it here also). My primary uses for the GH5 are slow paced walking videos on a fairly even surface and sit down interviews using a Tripod.

Focus performance is very similar to Samsung nx1 based on my experience. I'm one of those people that need simple accurate AF and I'm thinking the Canon 5D IV might be the contender here if the new firmware improves the crop factor and codec.... On my Canon C100, dual pixel AF is dead simple and dead on. There's not a tracking option or anything, I just focus in the center or grab focus and lock on and off with a button. But I really want 4K60! Ugh. I may have to consider a manual pull focus gear and hope the peaking on the GH5 is great... How is the peaking in manual focus mode?

Mate a bloody unreal review. Honest. To the point. Pisses me off people are downplaying this issue. Cheers from aus !

What a dis-appointment! I have yet to make a move from all FX to any mirrorless. I just keep waiting and waiting for someone to nail it. They all seem to have one fairly major problem that keeps me waiting and hoping... Awsome review Max!
