I just received my Angenieux 25/0.95 (type M2) with the proper adapter and all. Initial snaps showed the characteristics I was prepared for (slight but noticeable pincushion distortion, exposing at 0.95, and the like) but I wasn't prepared for the superb clarity this lens delivers! The CA/flare is quite low for this fast a lens. Contrast is quite good and the details it can provide are fabulous.
It does not cover the whole of the 4/3rds frame. I can live that because of its character and class.
Some shots from the first day out (all at f/0.95 and the whole frame).
It is below freezing, overcast and generally miserable weather. I could not hold out for longer than an hour on the street with exposed fingers.
