I installed it and first thing I wanted to do was experiment with the exposure compensation in manual. Well it sort of works. I can make minor adjustments but so far I can't go the full range from -3 to +3. Sometimes it will go a little both ways (+ and -) and others it will only adjust in one direction. So far, I haven't figured out the logic of how it works but it definitely isn't what I was expecting.
Focusing definitely seems better even on my 60.
