Originally posted by Basset I wonder if you would comment on the ease of focusing with the Leica M lenses. It would be nice to have a digital alternative to the overpriced, under-featured Leica digital models. (The ability to use a K-mount adapter is also quite nice.)
From a focusing and usability perspective, the Sony 7r and previous NEX cameras are a lot easier and more accurate than using a rangefinder, Due to problems with my eyes, I can't use a rangefinder very well anymore (even though my first camera was a Yashica rangefinder - but that was 35 years ago when I had perfect eyesight).
Basically you use focus peaking to get close to the optimal focus, then press the C1 button and fine tune the focus to perfection. In high DOF situations you don't even need to do any fine tuning. With practice, it only takes a few seconds to focus.
With the 7r, Sony has improved the focusing further. Pressing C1 once shows you the focus spot (area to be magnified). You can use the cursor keys to move the spot, then pressing C1 again magnifies, pressing C1 a third time increases the magnification.
I really wish Leica would release a camera without a rangefinder and use the same system as Sony. I would buy that in a heartbeat.
