As an A7r user at least I have the option of the 36 MP FF sensor. Yes often according to the tests you won't be getting anything like full benefit of what the camera is capable of. Leaving aside considerations as to what my technique and capabilities are as a photographer, I will encounter conditions, hand hold, use lenses that won't produce the capabilities of the camera.

 

But the same goes for any other combination of camera and photographer out there. If you were standing next to me with your E-5 or whatever and I am achieving  12 MP on my 36 MP camera, what will you be getting on your 16 MP quarter frame sensor ?
