This is one of the widest lenses for 35mm film movie cameras. Very rare lens. Made in 1988, only few year before production was completely stopped. So, it is difficult to find newer lens of this type.
Aperture range is T/3.2-16 (no clicks). f/2.8.
The lens has no focusing mechanism at all - it just don't need it having huge depth of field.
Optical condition is very good. You can notice some cleaning marks, visible in the flashlight reflection (there are no scratches on the front element) or at specific view abgles. Few dust particales inside. But no scratches, no fungus. The lens was tested at film studio, and it gives excellent image.
Actually, this is best 10mm lens I ever had.
Take note that this lens have quite short distance from the rear element to focal plane. It is not enougn to reach infinity focus with a DSLR (like Canon EOS), but it focuses fine with hybrid (mirrorless) cameras like Panasonic Lumix G1 (sample pictures were shot with this camera). Keep in mind that I don't have an adapter yet, so image quality isn't high (can't align focus plane, and there is much of side light passed to sensor). These shots were made rather to show view angle for different lenses (10mm, 18mm, 50mm).
Also, you can see sample pictures made with such lens by Edwin Lee (www.lomoanamorphicuser.com) on Panasonic DMC-GH2 camera. If you need full-resolution pictures, you may download zip-archive (size is 28Mb).
Some notes on these photos from Edwin:
There is little vignetting in the pics - caused by my matte box. I think it's fairly sharp given the ultra wide angle. If I wanted super sharp image I would've bought a Zeiss. Oh I should also mention that I had a Schneider ND filter on too, so it may have contributed to slight some softness.
