That's not at all the experience I have with my Zeiss f/1.4 lenses: I have a 50mm f/1.4 (older Rolleflex mount, not HFT), but it's basically collecting dust because I don't especially like 50mm lenses, though I did try it out once and it was very good. The 35mm and 85mm f/1.4 lenses are two of my absolute favorites. Even my LTM Soviet copy of the 1933 50mm f/1.5 is excellent, even wide open. If Zeiss says the lens was in working order, then I'd seriously consider a camera/adapter/focusing alignment or collimation problem.

Last year I bought the Zeiss Planar 1,4/50 ZE for my Canon 5dII. This lens is beautifull made, very solid, smooth focussing, very nice to work with. But it was not usable under the 5,6. <SNIP> ------ Unsubscribe or change to/from Digest Mode at: http://www.lrflex.furnfeather.net/ Archives are at: //www.freelists.org/archives/leicareflex/
