Asahi Optical (Pentax) 50mm SMC Takumar F1.4 M42 This can be used with Canon digital, Pentax Digital, FT, or MfT but seeing that this is an analog forum...works great with M42 and K-mount adapted. Snappy blades. On close inspection there is dust/specks on the rear element. Otherwise the barrel is clean and focus ring is smooth. Includes caps and boxed in a Pentax 50mm F2 box Asking $125 USA Shipped I am new here on Apug but I have been on FM for years and Yabe of course.
