Well, I own both this camera and the E-M1, and for different reasons. I dont see any other reviews comparing the two so I will try my hand at it. The bottom line up front: Ive owned the E-M1 for a year now and I love it as a daily shooting camera in the field because of superior ergonomics. The E-M5 mkii makes a great tripod and studio camera and can be useful for other specific shooting situations with its various features. Ergonomics: Simply put, the ergonomics of the E-M5 mkii are quite a bit behind the E-M1. The grip is insubstantial and if youre going to put the M.Zuiko Pro 40-150mm f/2.8 lens on the E-M5 mkii you NEED the battery grip. Its not even an option. Expect to pay an extra $200 over the base price for the grip. That being said, with the extended grip, ergonomic differences between the two cameras vanish almost entirely. Almost. My only other gripe is that the E-M5 mkii only has a single front programmable button vs the E-M1s two. This might not be a big deal for you, but for me, I like having my magnification and focus peaking right up there where I can access it quickly on the E-M1. On the E-M5 mkii I have to use the AEL/AFL (Fn1) button for peaking instead. I prefer the shutter button on the E-M5 mkii which has a solid half-press to focus and then a full press that bottoms out quickly for shutter release. The E-M1 has a floating switch that activates somewhere in the middle for autofocus and then releases the shutter very shortly after that. Its easy to accidentally snap a picture when you just wanted to lock focus on the E-M1. Functionality: I couldnt tell any specific differences between the EVFs, visually. The IBIS on the E-M5 mkii beats out the E-M1 by a hair with the lenses I use (mostly Noktons.) Manual focusing is pretty easy with both bodies, but I find that the focus peaking on the E-M5 mkii shows a lot more "noise" in the scene that is very distracting vs the E-M1 which tends to really just highlight whats in focus and nothing else. Continuous autofocus on both bodies is useless. Dont bother with it. Thats not why you want these cameras. S-AF speed varies with the lens, the fastest being the M.Zuiko Pro 12-40mm f/2.8 and the slowest being the 60mm Macro f/2.8 but the lenses generally perform equally on each body with the same lighting conditions. Anti-shock shutter and electronic shutter on the E-M5 mkii make this body a superior street camera (anti-shock is super quiet, electronic is actually silent) but beware rolling shutter while using the electronic shutter. The buffers on both cameras run out very quickly, however the E-M5 mkii will recover faster than the E-M1 with the new SDXC UHS-II cards (worth it if youre shooting multiple bursts or high-res shots.) The battery meter on the E-M5 mkii tends to be full until its not full vs the E-M1 which will actually show gradual battery discharge state. Image Quality: In normal shooting, I cant say theres a huge difference between the two. Noise quality seems the same, and I tested this doing astrophotography at ISO 2000 with both cameras on the same night shooting the same subject (Milky Way.) The E-M5 mkiis high res shot makes an insane difference, however. If you shoot still lifes or do macros or any other sort of controlled studio work I highly recommend it. It is even easy to configure high res shots with flash sync. Lightroom tends to claim your high res files are not actually photos, but Im sure this will be addressed eventually. Any subject movement will create very noticeable artifacts at 1:1 viewing. Nitpicks: The eyecup on the E-M5 mkii is just... awful. It falls off. Constantly. And you cant buy a replacement from getolympus yet! I already lost mine after 2-ish months. No such issue on the E-M1. The paint finish on the black E-M1 scratches off and flakes everywhere. Its not especially bothersome to me, but it might be to others. Conclusion: I like the OM-D system a lot. :) At the end of the day, either body gets the job done and thats all I care about. I have been using the E-M5 mkii as my primary studio body and the E-M1 as a backup and field body. If I plan to shoot candids or street I would consider taking the E-M5 mkii because of the various (quiet) shutter options.
