I've recently gotten some slides back that I took with my 20mm Russar. I'm
the one who originally posted that I thought I saw the bottom right corner
of the image to be out of focus in my version of the lens. I don't see this
in the slides, so I now discount the earlier observation. The out of focus
region might simply have been outside of the depth of field in the other
shots, although I thought it would have been inside.

The images seem quite sharp and contrasty. I generally shoot it at f/16 (or
a little smaller) at which aperture the entire focal range is within the
depth of field. Since it's such a short lens I can shoot at 1/30 without
worrying about excessive camera shake.

The Russian lenses are variable in quality--Marc Small knows a good deal
about the reputations of the various factories, but even if you got a lens
from a "good" factory I would make sure it could be returned after you have
a chance to evaluate it.

Good luck,
