Wow! Can you post a pic of the lens? I've never seen a P/KA Cosina.
I have a few Cosina primes:
28/2.8
55/1.2
135/2.8
200/4
I like them, Well built, good IQ, and nobody knows they're good, so you can get them at a fair price on eBay. I do have some minor complaints against them:
- They're all P/K mount (until pentagor made his post I didn't know they had ever produced a P/KA prime).
- They have a funny-feeling focus ring, but I'm wondering if that's something they acquire with age because the 55mm f/1.2 (which I bought new) feels different to the other three I have.
- They don't have 1/2-stop clicks in the aperture ring (but if I really want a half stop I just set the aperture in between clicks).
- They focus in the opposite direction to Pentax lenses (they go "the Canon way" ), but then almost all 3rd party lenses are like this.
But clearly, it didn't stop me from buying 4 of them
The 200mm f/4 is very compact, much smaller than the Pentax-M version, and I have it mounted on my LX right now in case a cute squirrel poses for me outside my office window
