*Contax
mount is quite different. In fact it's two mounts. The inner mount has
a focussing helical, so the standard lenses don't have one. The outer
mount is for other lenses which have their own focussing device. Its
difficult to measure. I have taken the locking pin for reference.
Some pictures:
A7 and the lens.
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 1.8.
F 8.
F 22.
Closest focus is 77cm from
the outermost
edge of the lens, F 8. Focus on
the program wheel of the camera.
This lens was a newer standard lens sold with Kiev cameras. It
can
be found for low prices, it's
very decent. Wide open it's quite soft at edges. Stopped down a little
bit, it's
sharp already. The lens has no
close focussing capablities. It is relatively small and
lightweight, particularly for a F 1.8 lens. A nice lens which offers
one usable stop more than a standard lens.
For the "Bokeh" of the different Helios 44 and the 103 lenses I have made a separate page.
The
Contax rf mount adapter is difficult to find and sometimes expensive,
but Contax mount lenses are often much cheaper than their M39 versions.
