Ok, here is where things go crazy. I have a friend who dropped by with one of the Platinum 300 2.8's with an adapter. The darn thing took great photos. Seriously I think this is an awesome camera for folks that are tired of lugging around on travel, say a D800E and a Mark III. Every lens I tried worked so great. I suggest getting one of the fastest chips, past a class 10 but if you do it works great.
