B/W photography with the MS Super Triplet 3.5/35 mm Perar lens, adapted to a Sony NEX-7

I recently purchased a very special lens that is hand made in Japan in very limited quantities. Individual lenses are numbered and the serial number is engraved in the front ring (mine is a Mark II design and version, serial no. #433). It comes with a Leica M mount, which can easily be adapted to the Sony E-mount and fits the Sony NEX series. The lens is tiny – it will hardly get any smaller. The aperture ring has no discrete stops and needs quite some force to be moved, which inevitably will change the focus ring as well. The focus ring, however, moves smoothly with just the right force.

The image quality is very good, I believe, with one exception which is not caused by the lens but rather by the NEX-7: color shifting across the field, with magenta colored corners. The magenta doesn’t show up always, or it is sometimes more enhanced and sometimes very subtle. In b/w images it doesn’t play a role, of course. Otherwise the lens is sharp and shows no noteworthy distortions or CAs.

(Bern, Bundesplatz. This one is not really sharp but I had to be fast to capture that smile. Two shots taken just a few seconds later are tack sharp, but boring because the smile is gone)
