Would the 135 F1.8 SPIRATONE NON-AI (82) WITH YS MOUNT 35MM SLR MANUAL FOCUS TELEPHOTO LENS fit a 35mm adapter like the letus35?

Rafael.

No one has answered so here is mine.

YS, is this a Yashica mount?

I don't know if Quyen makes a Yashica mount s you would have to enquire with him.

If the flange face (back of lens where it presses on the face of the camera lens mount), to focal plane (film) distance is in the ballpark of no less than about 40mm, then it may be possible for a custom mount to be made to fit this lens to the LETUS35.

I was actually considering it because I found one not that expensive at ebay not long ago under the nikon lenses but ended up finding the fast 85mm I was looking for for a nice price.
