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 in the center of the photo.
F 4.
F 8.
F 16.
Closest focus is only 36cm from
outermost
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,
not the
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.
