After buying three Leica R 90 Elmarits that ended up having fungus I have given up on finding a reasonably priced one that is clean, and am now thinking of the R 135 Elmarit. All I see online are shots from these that were modified to shoot on DSLRs. I plan on shooting one w/ a Leitax adapter on a Nikon film camera, but wonder if they compare favorably to the R 90 lenses. I can live w/ the 135 focal length as long as I can find a clean one (the prices on these seem much more reasonable than the R 90 variants). Does anyone here have experience w/ these lenses? Thanks.
