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.
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
dish to the right of the big solar panel near the center of the photo.
Closest focus is 77cm from
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
be found for low prices, it's
very decent. Wide open it's quite soft at edges. Stopped down a little
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.
Contax rf mount adapter is difficult to find and sometimes expensive,
but Contax mount lenses are often much cheaper than their M39 versions.
