Some pictures:

A6000 and the lens.
The grip is a Case Logic
grip attached to a Manfrotto 200PL style quick
release plate, a special plate made by HorusBennu for their grips. It
allows you to use the camera, with the grip attached, on a Manfrotto
RC2 Rapid Connect Adapter.
Sample pictures: You may click
on the sample image (except closest focus) for full resolution. The
full resolution image opens in a new window, so you can keep it open
for comparison. Focus is on the
satellite
dish to the right of the big solar panel near the center of the photo.

F 2.8. Lens is off focus.

F 8.

F 16.

Closest focus is 0.65m from
outermost
edge of the lens. Focus on
the program wheel of the camera.
This old
lens
was sold for Braun Paxette cameras. This one is a bit off focus. I will
probably try later with a different adapter. Wide open
it's a bit soft. Stopped down it's fine. At F16 you can see what it is
capable of, inspite of slightly being off focus. At F 16 there is little or no
diffraction, which is much better
than other lenses. Diffraction is a problem of the APS-C sensor size,
not the
lens (see comparison page). The sample pictures were taken on a dull
day, so there is less contrast. It's
astonishing, how short and light the lens is, even if you add the
adapters. A
nice very small lens.
The M39 Paxette Mount is the same thread as ordinary M39 (Leica), but
a different flange focal distance. Please refer to the Paxette
lens page.
