I like this lens. Particularly with the Phigment Tech Leica M-E-mount adapter, as it makes the adjustment of manual focus so much easier. This lens is also very sharp wide open, with much less chromatic aberration than other F1.4 lenses I have used (Contax Zeiss 50/1.4, Sony 85/1.4 Zeiss).
It also looks very nice together with the A7R. Don’t you think?
All the shots below were taken in Aperture mode at F1.4. The only other F1.4 lens I would shoot wide open is the Panasonic 25mm F1.4 Leica Micro 4/3rds lens, which is also very sharp wide open.
1) It is sharp in the centre wide open
2) The bokeh is very smooth
3) It looks great on the Sony A7R
