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
dish in the center of the photo.
Closest focus is only 36cm from
edge of the lens, F 8. Focus on
the program wheel of the camera.
Already wide open
picture quality is o.k. in the center, it's soft at the edges. Stopped
down it's astonishing for such
a simple lens design. Have a look at the full resolution image
at F 16 and you know what I mean. The lens has good close focussing
capablities. 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,
lens (see comparison page). The sample pictures were taken on a dull
day, so there is less contrast.
This lens comes from a Lomo Smena-8M, an entry level Russian camera.
Nevertheless it's a coated triplet. The Smena had only a zone focussing
device, this lens has apparently been transplanted to the focussing
barrel of an Industar 50-2 by a skilled Russian photo dealer/repair man
and then calibrated to M39 FFD. Focus is fine. It's an
extremely small and lightweight lens and it costs next to nothing. A
good lens to start with.
