Mine comes this week but as a owner of a D800e and previous owner of 40 and 60 mpx backs I just have to lay it on the line as I read these Sony threads and folks struggling a little with the 36mpx sensor. Folks this is no different than shooting the big guns of Nikon , Phase, Leica s or Hassy not to mention the Pentax 645. The bottom line your in 36mpx plus arena and your fighting a big bull with no red cape. Lol
These sensors need a lot of care with regards to sharp images outside the shutter vibration issue shooting handheld just magnifies the hell out of your technique. Your not going to get away with pixel peeping at slower shutter handheld shots like smaller sensors. Tripods play more into your technique and your abilities to handhold the camera. I think like many D800e users your expecting miracles in this area. It's not going to happen if your trying to squeeze every drop out of this sensor you need to up YOUR game and play with a diffrent set of rules. Also your going to need better glass than ever was needed with smaller sensors. We are talking unchangeable facts here and trying to cheat some of them you will be disappointed with results.
One problem as I see it this thing is small and light and the mindset is you can handhold anything smaller than a full bore DSLR easy but these cams where smaller sensors and did not require better technique. Let me say this another way a small and light cam is great to carry but with this sensor plan on upping your game with a better mindset to a plus 36mpx sensor as it will nail every flaw that you have. You have to take my word on this, been down this road and its work on YOUR end. I hate seeing people disappointed in there results so this cam comes with a very clear warning. Do not under estimate this sensor with sloppy technique. Now this creates more thinking, more work and more creative ability to get everything you can out of it. Seriously if you want to be sloppy and just shoot lights out than a 36mpx sensor may not be for you.
I feel like I just had to say this as a long time Pro and working instructor. Photography is supposed to be fun but crap results after spending your time out in the field is depressing as hell. That is not something I want anyone to experience so take this advice as it's the best I can offer to others.
