I was given an Accura Diamatic YS 135mm/f2.8 screwmount lens by a co-worker who had sold me a Yashica TL-Electro- X. He was under the impression this screwmount lens would fit the Yashica which takes the M-42 (Pentax/standard?) mount lens. This lens, while being the same size, seems to have one to many threads on the lens and therefore does not properly fit the Yashica. On the bottom of the lens it says 'YS-AUTO'. I am inclined to believe it might be for a later Yashica screwmount with Auto functions but can find no info on the Accura lenses. If anyone might know any info on these lenses including what mount they might be, I'd be most happy. I will probably try to trade for a lens I can use or sell and purchase one I can use. Thanks for any info. -Mark - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
