My NEX 7 just arrived this afternoon. So I put the Zeiss 24mm on it and got some quick shots around the farm. My first impression of the controls is very positive. I like to two dials since I almost always shoot aperture priority. I have the three controls I use the most, Aperture, Exposure comp. and ISO right at my fingertips. Works for me. The screen is the same as the NEX5N so far as I can tell, and the viewfinder is good, but I prefer to use the screen. It is nice to have the viewfinder there when needed, but I did not need it this evening. Here are three samples.
