The Sony lens is much better than Leica M 35mm lenses on the A7. Bokeh is very good, generally.
The only Leica M mount lens that competes is the CV 35 1.2, which is actually slightly sharper in the outer field at f5.6 and beyond. At f2.8 and f4, the Sony Zeiss is sharper off centre, substantially so at f2.8.
The Summarit-M cannot remotely compete with the Sony Zeiss on the A7/A7R and its one of the better Leica 35mm lenses on the A7.
I put a full-size file up on my blog from the 35mm Sony Zeiss so you can see the sort of performance its capable of on the A7R.http://thephotofundamentalist.com/?p=1103
I did a review as well http://thephotofundamentalist.com/?p=150
IMO if you are shooting the A7, the native lenses really are best. At 110g its a hell of a lot lighter than the CV 35 f1.2....
