Prime vs Zoom: Olympus 12-40mm f2.8 vs 25mm & 45mm f1.8 ep.123

[@AerialLensVideo]

Very good comparison! You always do a very thorough and objective presentation. In fact, often more informative than DPReview and DxO in many practical respects. Thanks.

[@RobTrek]

Thanks. I try to keep it simple and test for the things that I think matter in the decision process.

[@markmacthree3168]

@@RobTrek You done well Rob you saved me time worrying which one ....thanks man

[@kenpowell3558]

Great comparison. I have the 12-40 pro it covers everything I do, landscape, portrait, and street photography , so don't need to carry more lenses around as I want to keep everything light weight.

[@RobTrek]

Thanks. It's pretty much the swiss army knife of lenses.

[@PPISAFETY]

I really like these side by side comparisons because you actually tell us what you are seeing, rather than just saying. "This lens is better/sharper than this other lens." You point out what you are seeing, and we can decide if we agree, or if there is enough difference to make a difference in the kind of shooting we might do. There were a couple of lenses that I thought were "must have" purchases for my Olympus kit that I see I don't actually need. I know this is a lot of work. Thank you so much!

[@RobTrek]

Glad to help!

[@daverogers8926]

Interesting choice of subjects, Rob! I had been on something of photography hiatus the past nine months or so. I bought a PEN-F last spring in anticipation of an 11-day trip to Ireland. I decided I wanted a rangefinder style camera and the latest sensor, and I was going to be "committed" or "deliberate" in my photography, so I only brought along three primes, the 12mm/f2.0, the 20mm/f1.7 and the 45mm/f1.8. It was a self guided tour, so I did all the driving (on the wrong side of the road), and although my wife had planned our itinerary pretty thoroughly, there was a lot of day to day decision making regarding the particulars. Of course we visited many places that offered tours, and so we spent a good deal of time listening to guides and reading displays and the like. The net effect of this was a significant "cognitive load," that left me with little in the way of processor cycles for photography. I found myself doing mostly snapshots. At one point, I even asked my wife if I could borrow her 14-42mm kit lens, because I was simply too tired of swapping lenses, trying to get the "best" composition. When we visited the Cliffs of Moher, it was gray and windy and raining. A weather-sealed body would have been nice. When I got back, I looked through over a thousand shots and was just really unhappy with all of them. So, what I've decided is that a good "normal" zoom is the right lens for a trip where you're not going to be able to devote a great deal of thought to what angle of view might be appropriate. Just twist the zoom until you see it! And don't expect to do art, just record memories. A trip to a foreign country, even if you speak the language, is going to be somewhat cognitively demanding. You're learning a lot of history, and culture, trying to process it and place it in a context with your own history and appreciating all of that. You're not going to be just "seeing" the landscapes or the architecture. That kind of thing is more appropriate when you're actually in familiar surroundings and you're not thinking about when the bus is leaving (we took a bus for the Ring of Kerry - no way I'd drive that road!), or worried about looking the wrong way before stepping out into the street. Additionally, there's probably a lot to be said to be going on a packaged tour, where you're not doing the driving, the navigating, the pumping of gasoline into your diesel rental (the handle was green, dammit!). When someone else is worrying about all that, you'll have some processor cycles for what a good composition might be. In any event, my interest has rekindled, and I set out to buy the 12-40mm Pro this weekend; and because of the package deals being offered with E-M1 Mk2, I ended up getting both. If I were to make the same trip again, I'd just bring the E-M1 with the 12-40 and be happy (even in the rain). I'll stick with the PEN-F for out around home, or other places that are familiar. I do enjoy shooting with primes, so I just pick one before I go out, and then look for the shot. When everything is familiar, you can take a little time to look for the point of view or light that makes it unique. Sorry for the long comment. Enjoyed the comparison. Very much looking forward to getting the 12-40.

[@RobTrek]

I went on a 7 day trip and shot mostly with my em1.2 with the 12-40pro. It was definitely handy not swapping lenses in a new place. Never know what you're going to need. I do the same with my penf in familiar places where I've been a hundred times. Just grab a few primes and see what I can get. Thanks for sharing your experience.

[@lomoholga]

This is a good summary. Cognitive load is a particularly appropriate thing in your example

[@meganmcbeth6521]

I've only just come across this video after recently subscribing to the excellent channel. I have a 12-100 F4 for a travel lens and love it. It's not much bigger than the 12-40 and I have missed the extra light that a 2.8 lets in. Otherwise I have 17mm and 25mm F1.8s and the 60mm f2.8 macro for everything else. Great channel Rob

[@antonharefield8341]

Great analysis of of all the competing mental factors when on such a trip. However you brought back for me that awful heart sinking feeling, when I destroyed my wife's new diesel BMW with a full tank of unleaded petrol. (I still have nightmares about that day).

[@Jastik]

As always, thank you for ur work. Right now I am living in Finland and tonight was snowing pretty much, so I just woke up now at 8am to watch couple of your vids before to go to take some pictures outside. Thanks!

Thanks. Have fun in the snow!

[@rustinggently]

A very useful comparison Rob, thank you for preparing and presenting it. I find other thought processes can apply when choosing which lens to use. I am fortunate enough to have a collection of four M43 Olympus cameras. Two PEN bodies, which I use for Urban and travel purposes. I nearly always use the lightweight and tiny prime lenses (17mm and 45mm) on each body in this situation, hence a smaller, less obvious camera bag and more opportunities for stealth street photography - people barely see my 'toy' cameras. If I'm out in our glorious countryside and hills then its the OMD's and zooms in a backpack. The 12-40 at 40mm makes a superb close up (if not macro) lens for fungi and small plants, it also provides the most useful focal lengths for my landscape photography. I'm pleased to say none of them have enough time out to gather dust.

[@RobTrek]

Thanks for sharing. Appreciate you taking the time to write.

[@eilonyahalom4836]

Hey Rob! I love the 45 mm but its uncomfortable in small spaces. I was considering the 25mm, 17mm or going with the recent 12-45 F4. Having really hard time deciding. What would you do as a travel only photographer?

[@RobTrek]

The 12-45 f/4 is probably your best choice for travel. If you can, maybe add a prime lens for those low light indoor shots like at museums. I prefer the 17mm for that.

[@jeffdrew625]

Good, real world comparisons. I have all 3 lenses and no regrets- all on a Pen-f. The pro zoom is excellent across the range. The primes are great for dimmer venues and lighter bag weights. The Zuiko Pro lenses are amazing!

[@RobTrek]

Thank you! Yes, they are all great lenses! Love the pro lenses on my em1.2, but I find them a bit bulky for me on anything else.

[@clonmult]

I've got a 12-40mm f2.8 on order; and I'm now wondering if it is going to be worth my keeping the Panasonic 20mm F1.7 - it'll be an interesting comparison between the two, and I think that the only reason I'll have for keeping the 20mm F1.7 is something you alluded to in the video - low light usage. Although autofocus on the 20mm F1.7 is not that great in low light, even with my OM-D E-M1 II.

[@RobTrek]

I'd keep it. The 20mm a nice compact lens. The 12-40mm is much larger.

[@clonmult]

@@RobTrek when I bought the lens, it was for use on an E-PL7, so being compact was a major selling point - easily fit in a small sling bag. But since then I've sold the E-PL7 and have bought an OM-D E-M1 II. Size isn't so much of an issue now. But the 20mm is a fantastic lens - I love some of the shots I got with it from a walk across central london a few months back.

[@clonmult]

@@RobTrek I've just done a side by side (both at 20mm F2.8), and the 12-40 F2.8 Pro is sharper, better overall rendition of the image - my usage for it will be very, very limited.

[@Democratiser]

I just acquired this lens and am loving it. The look and the feel of the lens on my G9 are excellent. If they didn’t display different brand names I’d say they were designed for one another! I also love my MFT primes though. The 75mm is particularly brilliant.

[@sfayers3361]

Excellent video again Rob. Confirmed the findings from my 17 & 45mm f/1.8 primes vs the 12-40mm f/2.8 Pro comparisons. The 12-40mm f/2.8 Pro is an exceptionally good zoom, as is the 40-150mm f/2.8 Pro. Olympus make some fine lenses!

[@RobTrek]

Thanks. It's hard to find a bad lens from them.

[@myxsys]

I really love your reviews. You test for performance and bokeh of the lenses. Other reviewers just talk about the physical properties of the lens, then they showcase boring street/landscape photos they took with the lens at f5.6 and above. Thank you for taking the time to properly review and compare these lenses for what they are truly capable of.

[@RobTrek]

Thanks. I try.

[@RobShootPhotos]

Very good review. That 12-40 is very impressive. Nice job in showing closest focal distance. Speed of focus is great minus the extreme of very close to 4-6 feet back. I've heard by other people say the 12-40 is like having the preformance of multiple primes. Your video added to that idea.

[@RobTrek]

Thanks. I think when I switched from close to far focus, the contrast vanished and the camera had no idea what to do.

[@artiecisneros4691]

Excellent comparison, thank you. The 12-40 pro2 came with the OM1 and they're great together.

[@Leptospirosi]

Great video Rob! You might do the same for the 17mm and the 12mm Vs the pro zoom?

[@RobTrek]

I will do the 12mm soon, don't have a 17m. Thanks!

[@glenjarvis9448]

Really like your videos too Rob you have a relaxed but informed style, that comes across really well. For info Zumzifero, I have this lens (12-40 2.8 pro) and the 17mm 1.8. Quality wise I think they're both pretty similar from what I have read, but the 12-40 is a great standard zoom lens. I do like using my 17mm though sometimes as paired with my om10 body, it is such a small lightweight and fun combination. You gain the extra stop or so but you're obviously restricted in its uses (street, landscape etc) but I do love using it when circumstances allow.

[@evgenipoptoshev4112]

Another very good comparison video, thanks! The 12-40 Pro is build like a tank, but tanks are heavy and bulky, and this extra stop or more is precious sometimes .

Thank you! Yes, the extra stop is gold!

[@joonkethoh8293]

Funny how I did the other way round. I bought 25mm/1.8 as my first lens and then got a second hand 1240mm pro a few months after. 25mm is my daily lens when going to school/ work for street photography and random stuffs, while 1240mm is for travel and something I want to shoot. Should I sell my 25mm? How do you think?

[@RobTrek]

If you have the em1.2, then I'd sell the prime. On smaller cameras like the em10, I'd keep it. Only caveat would be if you shoot low light a lot, then the prime is a keeper.

Very informative review, Rob!! Do you have a video on 4/3 lens? I have the om-d e-m10 mark ii and am unsure of which lens to get to give me good depth of field for portrait photography.

[@RobTrek]

Hi. Sorry, I don't have any videos on the 4/3 lenses. As for m4/3, the 45mm f/1.8 is a great lens. The 45mm f/1.2 is excellent, but would only buy if you're doing paid portrait work.

[@JLiu-fn5gv]

Hi Rob, great work! Really informative video for Oly users! By the way, do you have any interest in the sigma 30mm f1.4 DC DN lens for M43? The price is about the same as 25mm f1.8 but faster. I was wondering if it will be a good lens for both portrait and casual use. I used to have 45mm f1.8. But the view is too narrow for daily use (especially indoor), so I replaced it with 25mm f1.8. I am not sure if it worth it to get another faster lens like 30mm f1.4 for better bokeh? Really wondering how is the autofocus performance comparing to the native Oly lenses.

[@RobTrek]

Thanks. I wouldn't bother with the 30mm f1.4. It's a relatively large lens and won't give you any noticeable difference in portraits over the 25mm. I tried it next to the panasonic 25mm f/1.7 and decided on the panasonic for the smaller size.

[@JLiu-fn5gv]

@@RobTrek That sounds very reasonable. Thank you for your suggestion!

[@martieleusink3479]

Hi Rob, Thanks for this comparison; very insightful. I already had the 25 and 45 mm primes, but bought an OM-1 with the 12-40 mm zoom because I wanted a versatile lens that should make for a rugged and weather sealed package. I think that the 45 mm and the 13-40 at the long end perform the weakest. That’s why I’m considering to buy the 45 mm PRO. What do you think? It’s an expensive lens, is it worth the money? Thanks in advance, Martie

[@RobTrek]

I don't have the 45 pro, but have seen reviews for portraits where the 45pro was much sharper than the 45 1.8. kzbin.info/www/bejne/rKqbpneYhtZshLMsi=i0YmHlRpjkh1f0HN

[@deenugent473]

Thanks Rob for the very informative comparison. I have the 45/75mm F1.8 already but don't have a lens for video like the 12/40mm F2.8. I am currently using the Zuiko 12/60mm Pro F2.8 that I'd used with my Olympus E3 for video on my E1 Mii. The only problem when using that lens is that during video mode, there is no auto-focus. I guess I really have no choice but suck it up and get the 12/40mm.

[@RobTrek]

The 12-40 is a great lens for video if you're going to be in situations where you're not sure the focal length you'll need. I used it for recording lectures where I wasn't sure of where I was going to setup in a room. However, for most things I found the 25mm f/1.8 prime fits the bill and gives me that extra bit of light.

[@gharrop1]

Another excellent comparison Rob, many thanks. The pro zoom is pretty expensive in the Uk but I suppose does cover several primes and is easier to use. Also the optical quality difference was virtually the same and thus much less apparent than it was with the kit zoom lens comparisons you did…is there any mileage in a straight comparison between the kit zoom with the pro zoom to help folk decide whether it really is worth trading up? Swapping lenses in a landscape environment is not much hassle, but in a street photography situation can be more fiddley, so The pro zoom must be in its element there?

[@RobTrek]

Thanks. I actually did a kit vs pro video last week. Spoiler, the pro is sharper but the trade offs are not worth it for the average person. I don't like the pro zoom for street work. It is ideal, but I break a sweat taking out expensive gear. I like the E-M10 + Kit zoom ($500) vs E-M1 + Pro Zoom ($2000+).

[@gharrop1]

Thanks Rob, really appreciate your comments....not sure how I missed that one... Will now catch up and watch it!

[@cmalc8]

I'm guessing the primes set to f2.8 sharpen up to slightly better than the 12-40 wide open, which would make them worth having for sharpness and portability. Is this correct ?

[@RobTrek]

Yes, the 25 & 45 sharpen up nicely. The 12-40mm is always sharper in the corners than the 25mm and about the same on the 45mm.

[@cmalc8]

Thank you @@RobTrek This means I'm happy with my 12-40 (amazing lens) and 45mm 1.8 But on the other hand the f1.2 25mm is very tempting ! despite the price.

[@RobTrek]

I'd go 17 and 45. I have the 25mm but rarely use it. I like the wider angle of the 17 and the short telephoto with the 45mm. For the GX85, you should get the Panasonic versions. The Pancake 20mm f/1.7 and 42.5mm f/1.8. There is a Pana/Leica 15mm that is excellent but a little pricey.

Hey Rob ! I have the 45mm and I LOVE it but I was considering to buy a new lens with a small focal length like the 25mm or 17mm but I think the 12-40 f2.8 can be a good opportunity. But I don’t really know if it could be better to buy the 12-40mm lens or the prime lens (25mm or/and 17mm) What do you think ?

[@RobTrek]

It's a tough choice. I'd go with the 12-40mm for the wide angle and close focus capability. However, if you already have the 14-42 kit lens, then get the 17mm prime. A kit lens with 2 primes is better than a single 12-40mm in my opinion. That said, you could sell the 45mm and put it towards the 12-40mm. A single lens solution with little compromise.

You are welcome!

[@rickbear7249]

Rob, As you point out in a reply (below), the relatively large and heavy (by MFT standards) 12-40mm PRO zoom is best suited to the E-M1 or an E-M5 MkII with the grip. Its size and weight kind of destroys the small-and-lightweight concept of MFT unless you really need a weather sealed PRO lens, whether a prime or a zoom. I've bought all three of the PRO series zoom lenses, plus the PRO 300mm f/4 and PRO f/1.8 fisheye. But NOTHING would persuade me to part with my pair of quintessentially small-and-lightweight MFT 45mm f/1.8 and 25mm f/1.8 prime lenses! Simply removing the grip from my E-M5 MkII cameras returns them to true micro cameras, and that's where the 45mm and 25mm f/1.8 lenses are superb. They're also a great match for the wonderfully small and lightweight Olympus OM-D E-M10 MkIII, where camera + both the f/1.8 prime lenses are smaller and lighter than the 12-40mm PRO zoom. Rick

[@RobTrek]

Agreed, mft is about being smaller and lighter. Using pro gear certainly gets better results but I haven't found a need professionally or personally.

[@jeffdrew625]

Third time viewed: on a Pen-f, I have all 3 lenses plus the 12mm f/2 prime and would add some comments. I just got back from traveling with them and banging out a couple hundred variety shots. I like the work flows of all. Overall, I prefer the primes on the Pen-f for balance & work flow & low light & occasional bokeh subject separation. OTOH, the 12-40mm Pro lens travels well, flexible range, sharp and excellent build quality! Some of the best candids were with the zoom! Pricing= oof dah! Do the math; primes vs Pro vs Budget. It’s only money! 🤪😂

[@artl52]

Hello Rob. I am getting back into photography after being away for a few years. I'm old enough to have started (almost 5 decades ago) with a Minolta SRT101 (by those days were a lot simpler - zone focus, aperture preferred or manual shooting, flash distance calculations for macro work) - anyway, I just bought an Olympus OM-D E-M5 Mk III and 40-150 f/2.8 and loving it. Even with either of the teleconverters, I am getting excellent hand-held shots I never would have with my Canon big, heavy, fast long zooms. I've learned quite a lot from you already and am thinking of getting a 12-45mm f/4 PRO Lens, mainly b/c my wife and I do a lot of travel and I want to bring a minimal yet high;y competent kit with me. I don't think I've seen you cover this lens (unless I missed it) and am very interested in your opinion, especially against a couple of primes - like you did in this review. I would get the 12-40 f/2.8 but it seems a little on the big/heavy side for travel photography. Thanks again for all you do.

[@RobTrek]

I don't have the 12-45mm so can't do any direct comparisons. However, Jimmy, Peter, and Robin have all vouched for it so I'm sure it's a great lens. I have my dad's SRT101 sitting right next to me. Great camera. Thanks.

[@geofff6671]

With the quality of modern zooms, fast primes should really be regarded as specialty lenses for shallow DoF photography. I hear lots of photographers say they are good for low light but this only applies when you have low light and also want shallow DoF. As soon a you want any significant DoF in low light primes offer no advantage and higher ISO, IS or tripod will be needed.

[@RobTrek]

The tripod just doesn't get the air-time it should. It should be the first thing you buy before you buy a prime.

[@valdiskrebs566]

Nice detailed comparison... thanks!

[@RobTrek]

Thanks for watching!

[@valdiskrebs566]

Rob Trek I like that fact that you are not an “official Olympus”[OO] person. You always give an honest review, even pointing out that the high priced option may not be worth it. The OOs seem to always be pushing the high-priced option, no matter what.

[@trulsdirio]

The AF performance was more down to the camera pre 3.0 update, than it was the lenses I think.

[@RobTrek]

Thanks. Most firmware seems to be lens and AF related, so this wouldn't surprise me.

[@rogerquenault7207]

As always a great informative video, I have both the 12-40 pro f2.8 and the 25 and 45mm f1.8 and agree with you findings on the picture quality I did think of selling them but decided to keep them for when I eventually get a pen f for street and b&w photography might even get a 17mm f1.8 to go with them for a full kit, I have taken a few indoor pictures with the 25mm f1.8 and the 12-40mm f2.8 pro and the extra shutter speed got me some pin sharp hand held pictures that I would have struggled to do with the pro lens. It always amazes me the number of topic you find to cove with your mft gear as mentioned before better than many so-called professional channels.

[@RobTrek]

Thanks. That extra stop of exposure and the compactness of the primes is why I use them on my smaller cameras. The em1.2 pretty much only use the pro lens.

[@proksalevente]

Did you get the 17mm? I currently own the 17mm, and I'm wondering if I should buy the cheap zoom (40-150) or the 25mm or the 45mm as my next lens. Any input would be helpful!

[@rogerquenault7207]

Levente Proksa the 40-150 is a good lens and has a huge range but is not anywhere as sharp as the primes, for myself I don’t mind changing lenses or moving closer (if possible) to have nice sharp pictures, both the 25mm and 45mm f1.8 are fantastic lenses and you wont be disappointed with what they produce as for which one is best for you thats a question only you can answer, I’d do a list of pro’s and con’s and see what that reveals, You might be lucky and find a a camera store that will loan you a lens so you can try them. I did get the 17mm f1.8 but have yet to purchase a Peen F, I’m holding back just in case they decide to do a mk2.

[@proksalevente]

@@rogerquenault7207 I think I'll just give buying used a go. I could get both of them for the price of one, with a lucky score. I probably want the 45 at first. Thanks!

[@proksalevente]

@@rogerquenault7207 If I could spend that kind of money on a camera body, I'd probably go with the em-5 III, but the pen-f and that inspiring retro look, I feel why you'd rather go for that! Let's hope they get it out quickly.

[@momchilminkov5722]

The flexibility of 12-40 range would make me buy the zoom. I would need like 3 primes to cover that range. They will be more money and constant lens changes. Now, if 12-40 was bad or even mediocre wide open, it would be another story. But it's sharp, so I'll just take the 1 stop hit on the ISO.

[@RobTrek]

Couldn't agree more. I prefer primes since they are smaller and I don't mind swapping. The 1 stop of extra light is a bonus but not critical. I'd be fine with f2.8 primes.

[@homesickphotographycomau4107]

can you please do the same with current new pro 17 45 25 all 1.2 in the same as this current 12.40

[@RobTrek]

I'm sorry but I don't own those pro lenses so can't do a comparison.

[@terrywbreedlove]

I have all three of these lenses plus the 75mm 1.8. The 12-40 is so good that it gets used constantly. It is my landscape lens of choice. The 75mm is brilliant and I use it for headshot just about exclusively. The 25mm is a fantastic lens that goes really nice with my PenF for street photography. I stopped shooting with the 45 as good as it is after I bought the 75 and 25 a couple years ago.

[@RobTrek]

I love my 75mm as well. On my last family photo shoot, I actually used the 45mm more to capture 2 or 3 people at a time. I rarely do headshots, but the 75mm would be my first choice.

[@terrywbreedlove]

Rob Trek Another good use is outdoors say on a beach shooting full body shots. It compresses the background nicely.

[@Quasquaquorne]

Super video! You really help me choose my future lens

[@RobTrek]

Thank you.

[@antondean]

Thank you so much for this comparison! It really helps!

[@RobTrek]

Thanks for watching!

[@c.augustin]

The 12-40 Pro is incredible - this is a *zoom* lens, and you used it wide open! It even holds up to the primes at 2.8, and this is the moment of truth. Your test mirrors my own experience with the 12-40 Pro (had it just for a day, but I was impressed of what I've got). If one starts out with Olympus MFT, I would highly recommend to get the 12-40 Pro instead of primes - it costs roughly the same as the fast primes of 12, 25 and 45 mm together, but you have much better handling (no camera bag needed, no changing of lenses). Thanks a lot for this comparison!

[@RobTrek]

Thanks. It makes a strong argument not to carry any other lens in the focal range. I don't think I mentioned that not changing lenses in the field also maintains the weather sealing. I still prefer the primes for the low light and that tiny bit of dof I can get.

[@c.augustin]

@@RobTrek Yeah, I already have these primes and would keep them (there are situations where they come in handy). Thought about the 12-100 Pro, but F4 is not to my liking, and the 12-40 Pro is just that good … well, my next lens for MFT should be the 12-40 (and it is my preferred range of focal lengths), and this quite affordable 75-300 for long-range shots afterwards (or the other way round, I don't know).

[@RobTrek]

That 12-100 is tempting with the dual stabilization trick. But yeah, the f4 limits it to good light or slow subjects. I bought the 75-300 first if that helps. I didn't see the need to overlap focal lengths.

[@A1Bokeh]

idk why but you had me cracking up. Think I will be getting the olympus 12-40. I never use zooms but I am finding that I may benefit from the convenience and versatility.

[@RobTrek]

I try to be somewhat entertaining but not everyone gets it. Thanks!

[@fernandoruizcuadrado]

[@RobTrek]

[@arthurrmcphee4885]

Excellent work Rob, my criteria is to have small lenses vs anything that is large and weighty. After Canon and the 70-200 f2.8 IS L lens which I still have, not sure why, the Olympus makes me want to go even smaller with the lens choices. These primes become tempting for the extra speed in low light and the advantage of faster focus in darker situations along with lower ISO, I don't shoot video but the comparisons work the same. Thanks for the video.

[@RobTrek]

You and I are on the same page. I don't care for the extra weight in street photography. I prefer kit zoom and small primes.

[@liluyvon]

Hi, thanks very good and helpful comparison!

[@DivisionStreetDrums]

Rob, has Olympus approached you about being a Brand Ambassador? If not you should contact them. Great video.

[@rickvestuto]

I felt that your eyebrow looked sharper on the 12-40 than the 25mm on my 2K screen But I also wear glasses so who knows The best gear is the gear that you take photos with ....right? Best regards, Rick

[@RobTrek]

Thanks. I think the minor differences you see are slight differences in the focus plane. I was walking back and forth with each lens swap, so not able to stand and the exact same angle and distance. At f/1.8 and f/2.8, minor differences like that will show.

[@rickbear7249]

Interesting, as I also find that my 12-40mm PRO gives sharper images than my 45mm f/1.8 on the E-M5 MkII. My guess is that's because the PRO lens has better optics than the tiny 45mm prime. That said, the 45mm f/1.8 is an amazing lens which even Olympus had difficulty in beating when they released their significantly more expensive 45mm f/1.2 PRO offering. Rick

[@seyedmahdiamiri4924]

Hi Rob. I wanted to consult with you about purchasing another lens. I have the following equipment: Body: EM10-Mark 2 Lenses: 1.Kit 14-42mm f3.5-5.6 2.45mm f1.8 3.75mm f1.8 4.40-150mm f4-5.6 What do you want to recommend as my next lenses? Saturn in Germany has a good deal on 12-45mm F4.0 PRO only for 300 Euro. Does that make sense to buy these lenses?

[@RobTrek]

If you primarily use your 14-42mm, then the 12-45mm is a nice upgrade. I'd really only consider it if you want the weather sealing or are unhappy with the sharpness of the kit lens. I think better options might be the 9-18mm, the 60mm macro, or 75-300mm. These will expand your photography more than getting another lens that your 14-42mm covers in terms of focal length.

[@seyedmahdiamiri4924]

@@RobTrek First, thank you for your feedback Rob, I always learn from you . Secondly, I like to do street photography and portraits but I lack the equipment for landscape, architecture and macro photography. I thought maybe this 12-40 F4 Pro will help me in these areas, but I'm not sure

Hi Rob, i have seen this great video. I had the zoom 12-40 with the Em5II. Great couple! But i sold them. Now i have one em10ii with the prime lenses 25, 45, 60 due to weight. The 12-40 is very good zoom lens but big for small cameras. If you dont want to change lenses, and you dont mind the weight, buy the zoom. On the other hand, buy prime lenses. I love olympus and i am a novel user in photography. Pd: sorry for my english.

[@RobTrek]

Yes, the 12-40 is a little awkward on the smaller bodies. I prefer the primes, but use the pro on my em1.2 mostly.

[@TheRealRichardBlack]

Hi Rob. This was just the info I needed. I do some street photography with the 17mm 1.8 as well as photos of bands in bars and clubs,but have been wondering what to go for next. I like the versatility of the 12-40 but what has me maybe looking towards the 45mm first is being at 1.8 for the low light. Any advise would be very much appreciated.

[@RobTrek]

I'd start with the 45mm. it's cheap enough that you'll never regret getting it even if you get the 12-40 pro later. If you have the EM1 mark II, I'd strongly suggest the 12-40 pro first. It's a bit heavy on other Olympus cameras for me, but on the EM1-ii, it's a perfect match.

[@liutony4872]

Olympus 12-40mm comparison: Great tests. Btw MTF tests probably are shooting at flat surface instead of 3D subjects.

Yes, if you don't need the faster aperture and don't mind the extra size/weight, the 12-40pro is excellent. How do you like your 14mm pany? I hear the CA is bad. Is it really?

[@chrisbrown6432]

I think the 12-40 focused pretty well. The 25, not quite as good as the 12-40. Definitely slower. The 45 was also kind of slow.

[@RobTrek]

Yes, the 25mm did best against the 12-40. The 45 is okay, but not a focal length used much for video anyway.

[@iDATUS]

[@RobTrek]

[@zardosspinosa6944]

to my eye the primes were clearer by a good margin, that combined with the wider apeture would make them the better choice opticaly, sure the 12-40 2.8 is still damn good but you are sacrificing weight depth of field and IQ, the 2.8 Pro zoom represents an easier approach, but ultimately although more of a hassle, you will get those marginal better results with the 1.8 primes

[@RobTrek]

You've summed it up nicely. Thanks.

Hi Rob! Great video once again. "The Panasonic doesn't count..."😂 That lens is slow to focus indeed. I have a few primes myself, including the Oly 17mm f1.8 which I love, especially because it was my first lens and it's a fast lens to focus. Primes have top notch IQ generally, but that 12-40 f2.8 is my favorite lens, it's the lens I use the most. It's so versatile, the IQ is amazing and it's so fast to focus! It's almost like having a 4 in 1 lens (12mm, 17mm, 25mm and 45mm). In fact, I only use the primes when I really need that fast aperture. Thanks for the great comparison video, with real life situations as always. 👍 Cheers!

Still, when you love something, you forgive it's faults. I bought it used and paid less for it than a couple of cameras and lenses combined.
