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: TOP ergonomics and customization, Always perfect white balance and exposure, Monstrous and small Zuiko lenses at a negligible cost compared to the competition, Beautiful color rendering and customization possibilities, Burst. Powerful computational functions with amazing results

Cons: Dynamic range not at the level of the best APS-C, Difficult to get a blur even with the F2.8 zooms because of the MFT sensor

Opinion: I sold the Om-1 to switch to Sony A6700, much praised as the best APS-C out there but between the two in my opinion the Om-1 comes out the winner, even in the noise at high ISO it comes out on top, with a noise that is always soft and pleasant. The only thing where the 6700 is superior is tracking. The Om-1's single-point autofocus, on the other hand, locks on more than the Sony. Overall, shooting with the Om-1 associated with the slow Zuiko 12-40 2.8 or the super-bright fixed is a rewarding experience. It produces beautiful images very easily. Since I got the Sony I've started to worry about white balance again, which with the OM-1 is always perfect by default.

Pros: Lightweight, the best ergonomics I've ever had, lots of cool features.

Cons: Image quality, not exactly high iso performance, high cost in relation to image quality.

Opinion: Beautiful camera, very comfortable but with some significant flaws. At iso 3200/6400 it is already over the limit for me, too much too much digital noise that makes you lose detail and makes it difficult to clean even with the best software. I owned the OM1 and the Z6II, paid the same but in the evening the Nikon is clearly superior in terms of image. Unfortunately it is comfortable but with the FF in terms of image quality there is nothing to do, it is superior and by a lot. Disappointed not to be able to go beyond 3200iso I resold it, it costs too much for the limitations it gives.

Pros: Lightweight, tropicalized, rich in functions

Cons: Non-intuitive autofocus operation. Finding the best setting is a challenge

Opinion: Bought 2 years ago, after having had everything. It's not a machine for all uses, I prefer to photograph events: concerts, cabaret, theater. In such contexts the depth of field is welcome and even in low light I work well. It is clear that the lenses must be bright, the 2.8 pro or even better the fixed 1.8 of the house (17 and 45). The combination with the Leica 25 1.4 is also excellent. The white balance is splendid even in cars with difficult lights. The exposure has to be accurate, I don't go beyond ISO 3,200 and jpgs are perfectly usable. In desperate cases from RAW a couple of stops I recover them without problems. Great battery life, viewfinder vision. I've also tried the birdlife, but in reality the only one I'm really interested in is the female sparrow. Unfortunately, it has devalued a lot with the release of the Mk II, not least because of the feeling that OM Systems' support of this is not up to par with a Pro camera. Let's not forget that it's the last one with the Olympus logo, time will be gentlemanly.

Pros: Performance, ridiculously low price for what it offers, excellent image quality up to ISO 12800 and more. Ah!! : calm and cool !! the long-awaited update 1.7 that with which now the autofocus of the OM1 and the high resolution shooting would have improved a lot, according to those who downloaded it at 11 pm and at 11.01 have already noticed obvious improvements ... in reality it has not changed anything .. everything is identical to before

Cons: Dynamic range sometimes a little limited, continuous autofocus still a little behind the FF flagships. Criminal devaluation of second-hand vehicles, often by retailers, even official ones. it is NOT suitable for the hurried, who in fact systematically resell it after three hours saying that the image quality sucks and that it does not focus on one ... A classic
