I have a Takumar 135mm f2.5 lens that I have used on my 35mm cameras infrequently. I have tried it several times on my K10 and I am highly disappointed in the image quality and contrast of the resulting photos. Invariably the images are hazy and low contrast, however in focus.
Has anyone else had experience with this lens. It isn't a SMC lens and possibly that is the reason it's image quality is so poor. For now it stays with my daughter and my ME Super and the Pentax SMC M-28-50 zoom. The reason I'm saddling her with it is because it does seem to work OK on a film camera, and secondly she's not likely to use it very much. I've read elsewhere that it might be one of the poorest lenses that carries the Pentax name. Is that correct?
