CPC Phase 2 CCT 135mm f2.8

There's this tiny store in Littleton, CO that sells used manual camera gear and they had a few Pentax lenses that I picked up for $20-30 each (55mm 1.8 takumar and this 135mm f2.8).

Here are some photos of the lens.

The front lens cover is original and the glass is super clean, the aperture (6 blades) is snappy and oil free. It also came with a 2x teleconverter by the same company. From what I can understand, the CCT means Closed-Circuit Television and, apparently, CPC developed these lenses for Pentax. The lens is very usable. Here are some test shots done at F2.8

The last photo is it's closest focusing distance (1.5 feet). It says made in Japan and, other than that, I have no idea how rare this lens is or if it is only worth the $30 I paid for it. I did a search through the forums and didn't find much more about these lenses.

Let me know if you know anything about them! Thanks.

I'll post a Herb Keppler article on these - they are in fact made by Pentax via an entity "cosmicar"

I don't have any more info about them, but I have a very similar lens. It was in a collection of gear I inherited several years ago and I was under the impression it was a Soligor (the name on the case that the lens was in). I thought the "MC CPC Phase 2" on the lens bezel were specifications, not the brand.

Mine is also 135mm and F2.8, but the filter size is 52mm, not 55. The lens cap has the same logo on it as yours and it's got a built-in telescoping hood. I guess this brand is somewhat rare since yours is the only other one that I've seen. However, if they were made for video equipment, that may explain the lack of representation here.

With all due respect, I think CCT means "Computer Controlled Technology".

looks a lot like my rikenon 135 F2.8.

It may be interesting to compare indoor and outdoor shots.

My rikenion has an issue with rear element/sensor reflections. FIrst and only lens like that I have
