Sony A7 with 55mm F1.8. I find that the Sony A7 is a wonderful still camera. With a tripod it takes solid shots with good clarity. Night time shoots were quite bright due to the ample ISO. I was more focused on learning the controls on the Sony so I did not focus on comparing it with the Nikons. The 55mm was very subject to camera shake, whereas I felt more accurate shooting with the Nikon (perhaps because I'm very used to shooting with Nikon). The Nikon felt not only larger, but more secure in my hands. Using a prime lens with both I had less shake with the Nikon. I will have to experiment more with the Sony. Just giving an update.
