asahi pentax 135 2.5 ????

This is probably a dumb question, but after using this lens for many years, I am only now noticing that it says "Asahi Optical Company Takumar (bayonet)". It does not say Pentax. I bought it from Pentax way back in my K1000 days, and now that I'm getting ready to sell it, I'm only now noticing the name. Am I missing something here, or is this not the same as the Pentax? Thanks!

Pentax was founded in 1919 as Asahi Optical Joint Stock Co. In 1938 it changed its name to Asahi Optical Co., Ltd

Takumar is just a name that was given to the Asahi Optical lenses, named after Takuma Kajiwara.

Takumar - Wikipedia, the free encyclopedia

In short, yes, its still a Pentax

Hope this helps

Not SMC, but in my experience, still a rather good lens. I paid $71 including shipping for mine, was worth it. I think I did overpay slightly at that rate but not too much.

It is a Pentax lens, but it does not have the SMC coating that the K version has. I paid $35US for mine in early 2006. It's not a great lens, but it's not as bad as some people suggest. The lack of coating means it's subject to flaring if pointed toward a strong light source.

The older, screwmount Takumars are very solid performers and some of the K mount models as well. Pentax re-used the brand name of Takumar for some lower-quality lenses in the 1980's. The autofocus Takumar F series should be avoided if you can get the SMC F equivalent.

I suggest you check out Bojidar's site or the Splosdb if you have questions about the individual Tak lenses.
