KCS Posted February 7, 2010 Share #1 Posted February 7, 2010 Advertisement (gone after registration) When using a non-Leica lens that does not appear in the 'manual' lens list and is not coded, what is the best thing to do? Choose the closest option in the manual list e.g., set manual lens detection for a 35 f2? Something else? Karen Link to post Share on other sites More sharing options...

lars_bergquist Posted February 7, 2010 Share #2 Posted February 7, 2010 I did that and it worked out well. The specimen I bought exhibited some pretty strong decentering however, and I have dumped it, but that is a different matter.

KCS Posted February 7, 2010 Author Share #3 Posted February 7, 2010 Thanks Lars. By decentering do you mean focus shift? or lack of sharpness? The reviews of the lens have been generally good, but I've never been happy with it on my M6--just doesn't seem sharp at any aperture (though I'm comparing it to a *really* great 50 'cron that I have). I'm going to take advantage of digital to experiment a bunch with it and then decide whether to keep it or stick with 50mm until I can recover from the M9 purchase enough to get a better lens.

Bo_Lorentzen Posted February 7, 2010 Share #4 Posted February 7, 2010 Hmm, I coded mine as the nearest performance wise which seemed to be a 35mm summarit 2.8 - Am very happy with how this lens render, I would venture to say that my particular example is the sharpest non Leica 35mm I have played with in this range, but being a CV there seems to be quite a lot of latitude in the QA. .

Karen Decentering occurs when one of the lens elements is not perfectly aligned along the optical axis. The typical result will be that one side or part of the image will be soft while the other parts are just fine. It seems to be a particularly common problem with the CV lenses. That said, the bulk of the CV lenses are just fine, and are extremely well made mechanically and optically. Jeff Link to post Share on other sites More sharing options...
