I've had Fuji X100 for a while now . I am very impressed with image quality vs. my Panasonic m43 set up. Everything is clear smooth sharp and noise free even at 100%. Sometimes I am tempted to try out one of the interchangeable lens Fuji X models to get that same quality in different focal lengths. However, I have this suspicion that at least some of the X100 clarity is due to that quiet shutter. I have photos take at as slow as 1/4 sec that are pretty decent. Would the clack of the XT1 or XE1 shutter result in less sharp photos than comparable photos from X100? If anyone has experience with both X100 and other X cameras could comment on this, I would appreciate it.
