Pros: Portability & features

Cons: None so far

Opinion: Have been working with this gem for some months now. Been working with MFT since 2013 besides my Nikon gear and have seen a steady but impressive development of this formula. For me the OM-1 (and its lenses) is all about portability while being able to produce high quality output that can compete with camera's with a larger sensor. In my opinion OM-Systems succeeded to produce a camera that does just that. There is so much to tell about this camera. To sum this review up: Fast AF, doing great on high ISO, customization and creating presets works well. Button layout. Battery life. I can go on and on.

Pros: High ISO tightness: yes, I used it up to 40,000 iso. If you want to see the file, I can send it to you. The details remain, with the artificial intelligence of Camera RAW for noise reduction, we break down many barriers but the merit also goes to the file of the machine because it manages to preserve colors and details excellently. 12,800, 16,000, 20,000 and 40,000 ISO with bad light, indeed, I can say even in the absence of light and the little that there was, in my working condition, were colored LEDs .. I didn't miss the FF. WARNING: I am not making comparisons. But I'm saying I thought worse and my thinking was all the wrong points of view. I worked in the same event with both Om and Sony a7iii and I noticed the difference in 3 hours of sporting event, only in some rare cases and only one stop difference. The camera is excellent and the speech lightness, portability, excellent lenses and stratospheric quality, tropicalization ... they do not make me miss the only stop I mentioned above of difference in favor of the FF that sometimes can come out. Ergonomics.. As a whole an excellent machine with which you can do everything: from wedding to sport to fauna and landscapes. If you know how to use it, if you know how to use the m4/3 this machine can be the point of arrival.

Cons: The real cons are: 1) viewfinder when the light is bad (Otherwise it is a great viewfinder). It goes jerky and loses so much quality. Even here, once you know about this limit, you accept it and live with it and try to improve yourself as a photographer (problems that I also found with the two Sony mentioned below) 2) in the video field: I did not succeed, so if someone maybe solved, I could re-evaluate this point 2. That is the backup!! Obscene! For videos I did not find any possibility to save the files simultaneously in the two tabs and not even to use the second card when the first is full!! This, those who review the machines should say! Because it is a point that you get there only when you actually run out of card and we could find ourselves really in difficulty. So, in the video field ok stabilization, excellent file that comes out ... Excellent menus... But memory management is WORTHWHILE. Absolutely rejected (I speak video department). For a professional, or at least for me, for my way of operating .. It is unthinkable not to be able to make video backups. Point 3: the rings in which I manage times and apertures... Too recessed, so a bit uncomfortable. When I pick up the X, for example, a whole other world of comfort. Step 4: The joistick. Good but there is better.

Opinion: The AF is not comparable to the FF super flagships but not so much below. More than AF... I correct myself, the tracking is more nervous and dancer. The af as reactivity I can easily place it on a par with the FF flagships (I come from Sony A9ii, Sony A7r5). I waited months to be able to say this and those who say otherwise make me wonder "how did you test the car? Have you really tried it?" And... If we are not yet objective, then I wonder about the quality of the preparation of the individual himself. The car unlike competing flagships, does not forgive you if you make a mistake. While with the others you can afford to make mistakes because there is so much the machine that remedies .. With her you can't. You have to know how to photograph. One stop or two of underexposure, sometimes even three, and one stop of overexposure you can afford. More is a risk. But if you really learn to use it, it doesn't give you any problems whatsoever. On the contrary, it pushes you to improve yourself as a photographer and once you improve, it does not leave you behind. So for me it's a point of quality. Like any product there are advantages and disadvantages. As well as sensors: M4/3, FF, super FF and so on... The blanket is always the usual short blanket. It is up to the professional to identify what interests him and his profession or passion. There is no best or worst, but the best for the individual himself. All the rest is bar chatter that leads to nothing but not improving ourselves. The camera is excellent when combined with pro optics. To really high quality optics. Then you will not miss anything. If you mount enough optics... You will have enough results. Here's how I think about it. Who buys this machine, can not have kit lenses. With lenses 1.2, 1.4, 1.7, 2.0... 2.8... and also with the F4... We can work very, very well. I recommend the Zuiko as a first choice but also the panaleica (the top) are exceptional. That said, I have reduced weights and backpacks a lot. I am a photographer who lives and works in photography from events, shootings and weddings to work around the world for author projects related to flora and fauna. I need the machine to move all round. I need portability. And don't say that the machine is as big as the other FFs. Because it means that you have not understood anything at all. The machine has the volume it needs to have. It's the lenses that really make the difference. And for those who travel the world and need hand luggage and do not have problems with weight and volumes .. This is a great alternative.

Pros: Lightweight, relatively compact, robust, tropicalized, ergonomic with stacked sensor and many useful functions, easy to use

Cons: Noise at high iso, but with the right lenses and a good post-production everything adjusts

Opinion: I come from Canon FF and even before that from Sony mirrorless FF, but the transition to the M4/3 system was not at all traumatic. The machine is excellent from all points of view, even outperforming compared to my needs, which are also quite uneven. I appreciate its functions, size, weight and the feeling of solidity and cleanliness that it transmits. Excellent autofocus, which rarely makes mistakes or sticks. Great high-resolution shooting even handheld, but all the other opportunities (and there are so many, not least the possibility of shooting sumptuous bursts up to 120fps!) make it a real treasure for those who love photography. I appreciate its ductility, its relative ease of use and, of course, the fantastic shots it allows you to make, combined with the excellent and light M.Zuiko Pro lenses, which did not disappoint my expectations in the least.

Pros: The stacked sensor raises the level of performance, computational functions and AI do the rest. Compact, lightweight, ergonomically almost perfect. Weather-proof.

Cons: Noise above 10000ISO, but still better than the other M4/3 I own.

Opinion: I've owned it for about 2 months, so I haven't tried it thoroughly yet. However, I can say that, for photography, it is a significant step forward compared to my other cameras of the same format. Above all, for birdlife and wildlife photos in general, AI AF co is nothing short of mind-blowing. Even shooting at very high speed is. I haven't had a chance to try other computational features like high-resolution shooting, etc. However, it seemed important to me to share these assessments of mine.

Pros: Operating speed, autofocus, ergonomics, tropicalization, computational functions, stacked sensor

Cons: High iso noise (but this is known and still solvable at the time of shooting and post production)

Opinion: The OM-1 is a really great camera. I was awakened by the pleasure of shooting... I come from Sony (6 years), and I removed all the kit including the A7IV to build me a micro 4/3 kit. No, I'm not crazy, indeed I'm very happy and satisfied with the choice I made because after a long time and many brands (I tried them all except Pentax), I'm savoring again the pure pleasure of taking photographs. The merits have already been written in previous reviews and I confirm them all great ... I just add that shooting at 50mpx handheld only when needed is very cool!!! Another advantage that I found is the dynamic range on the highlights, which stands at about 3/3.5 effective stops against the actual 2/2.5 stops of all other full frame and apsc cameras. The cons I would summarize them with noise at high iso... But if you understand how the M4/3 system works and shoot with a correct exposure, the problem is also solved because in post with proprietary software exceptional results are achieved.
