This is a cinematized SMC Pentax-M 28mm f/3.5 (de-clicked and coupling lever removed). I used it on a T2i (equivalent to 45mm) with great results, but moved to a faster version. Requires the $9 PK to EOS adapter from China (tons of those on ebay) for use on Canon DSLRs. Lens is in good shape as is the glass, some very light abrasions on both the front and rear elements but nothing that will impact overall image quality. No fungus or dust inside. Focus and iris are buttery smooth. Its a great little wide prime.
