I love my M8, warts and all, but the shutter is like a bomb! It has never really bothered me, but I know it's there. Finally tried a friend's M9 the other day and the shutter was sooooooo soft and smooth. With the M8, I believe you can get an upgraded shutter (to M8.2 standards), but how does that compare to the M9's? I don't have the finances to upgrade to a full on M9, but a 'minor' upgrade on the shutter may be a possibility..... Thoughts, experiences?
