If you set your NEX on a tripod, and focus on a flat contrasty subject a couple of meters away, you can very easily see focus shift.
Using just the 7x mag, with a Jupiter 3, I can see the shift readily from 1.5 to 2.8, and it's many degrees of focus turn.
Something you'd never see in real-time on an RF camera, digital or film.
Very cool. Long throw (~180 deg) focus lenses are your friend for accurate focusing!
It is interesting that u4/3 users haven't seen this (or have they?) perhaps the sensor is too tiny??
