I'm sure we've talked about all these cameras before separately, but let's put the comparisons all in one place. Needing a small interchangeable lens mirrorless to function as my take-with-me-everywhere/street camera that is good enough to serve as an emergency backup camera should my D800E crap out for what ever reason. Availability of f2.8 or faster lenses is very important Higher ISO is less of a concern Higher FPS bursts preferable (5+) MUST have a viewfinder. I don't care if its EVF or OVF. I'd consider a different camera without a built-in one if it's got an attachable one and is exceptional in other areas. I've read online reviews, and most of them aren't much in the way of helpful, putting them all into a similar class. They all seem to perform admirably, but what I'm more concerned about is ergonomics, and future success of the system. I don't want to spend 2 grand on a camera system that's going to drop out of favorability like my Olympus E system camera did. (I bought my E-420 only a year before olympus cancelled new development in the line.) The OMD seems to be the front runner in this regard, but I'm hesitant with Olympus cause it's hard to rebuild trust! Olympus you hurt me! lol The Fuji seems to be growing VERY quickly The Nex is fairly well established but I'm hesitant with Sony just in General And the 1 V2 seems to not be quite so widespread.
