It is a c-mount cine lens with a long narrow tube-like rear end. I cut away 2.5cm the rear most part of the lens and inserted it into a M42 focusing helicoid for use on my K5-IIs. It works very well! What's you comment on the performance of this cine lens on APSC sensor?

Very nice! Crispy with good colors and smooth bokeh. I own two Century telephotos, Tele Athenar II versions, which were intended for 35mm photography. They are both very sharp lenses, so I would expect nothing less from yours.

Yes, they are good! I have a Century 6" f/2.8 in c-mount. Will convert it into M42 later and then share photos with forum members. Smile

Below shown how the lens was converted.

Very Happy Very Happy Very Happy

It is a very fine lens indeed, perhaps the sharpest 200mm lens I have.

Mine is a variant of yours, designed an an slr lens because it has a preset aperture. The family resemblance is clear though.

You got some very nice shots in your post. I particularly like the seagull photo. However, it appears that the front element of your version is scratched or with coating issue . Why that didn't affect the image quality at all ? Question

Telephoto lenses are usually not affected too much by scratches or coating issues on the front element. I've mentioned this here before, and I'll mention it again briefly -- I used to own a Nikon 180mm f/2.8 ED that had a big chunk taken out of the front element. It was a LOT more than a scratch. It was a gouge. I bought it from a working pro, who claimed to have taken many great photos with it, and the only reason why he was selling it was because he was moving to autofocus. Anyway, because of the front element damage, I bought the lens for very cheap. I loved that lens -- it was one of the sharpest lenses I owned. And I could never see any degradation of images that I'd taken with that lens because of the missing chunk of glass.

A6 Intruder Cockpit -- Note Garfield -- Nikon F2A, AIs 180mm f/2.8 ED, Fujichrome 100.

Great colors and bokeh! I loved #5 and #6 images the most!
