It says KR on the aperture ring, so I would suppose so (also means it's got the dreaded Ricoh pin). However, I would ask the seller for a pic of the mount if you're actually interested in it, just to be sure.

Can't see the mount in the pictures, it's capped, but I doubt it's a K mount. All the other lenses the seller is offering are Minolta.

Looks to me like the 135 is a KA mount. Also the "Sears" 60-300 and the "Sears" camera are probably K or KA mount. The rest are that other brand.

I'm kind of curious why it sold for so much? 135mm 2.8 lenses are a dime a dozen (worth less just because there are so many used ones out there just like some of the 50mm kit lenses). I don't know anything about that particular lens but made in Korea would leed me to believe its not a top notch lens either (there are exceptions of course and I havent researched that particular lens). It seems plenty in that mount have sold much cheaper too. I guess thats ebay for you.

Don't worry about it. Like ripit says, there's plenty of them out there for cheap.

I have not seen alot of the PKA ones on the Bay but I been thinking about picking one up after looking at some shots by others seems like it would be fun to have

Re: the lens in question -- It's definitely KR aka KAR mount, not Minolta. I had a copy of this and it only had the non-bothersome Ricoh nub, not the toxic pin, but other copies may indeed have the pin. The sales price of this one is not totally nutz -- I sold my copy last year for US$31 and the buyer expressed great delight with its optics. That's my story and I'll stick with it.

Not always KAR (could be simply KR with no A contacts), though based on the aperture ring markings "(A)P", I would suspect that both Ricoh and Pentax systems were supported. This arrangement was common at one point and the Ricoh "pin" was often enough a fairly innocuous ball-knub that is pretty compatible with Pentax AF bodies.

Build was excellent, made by Samsung Samyang, just a Ricoh nub, easy close-focus transition. I sold it because it showed more PF than I liked but the buyer was happy, said it was very sharp.

I wasn't aware that any of the major Japanese companies (at least with older manual lenses) made lenses in China, Korea etc. You learn something new every day around here. Of course these days its more common to have non Japanese plants. I came close to finding a good korean one (not that I have had many Korean lenses at all). It is a kalimar 35-70mm 2.8 constant )actually I have 2 but one is dead). Image quality is surprisingly good but build quality is crap.
