I shot with the Q2 Monochrom almost daily for 4 months and then sold it for the M10M. I really wanted to like the Q2M and the images I took with it is beautiful especially at f/1.7. What I didn’t like was the autofocus. Basically the Q2 AF is most dependable is when you look through the VF or the rear screen, press the shutter half way so the little rectangles light up confirming what is in focus. If you shoot this way then by all means it’s an excellent camera. But if you shoot fast like in a street situation where the subject is in the frame whether in mid frame or closest to the lens where you expect the camera to properly focus depending on the chosen focusing mode then the camera will disappoint you by locking on some random part of the frame. The camera works best with single point focusing dead center and your subject is also dead center but still the focus point will wander and from time to time you need to check if it isn’t at some corner because it can’t be locked in place. So…for street and fast shooting a NO. For all other subject matter a big YES.
