Nice document, I wish they made their lens(es?) as good as this information sheet. 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. I felt I got a better image quality when using a pinhole camera. It had a terrible vignetting which disappeared slowly by stopping down. And the (un)sharpness in the corners was even worse, which completely disappeared at 5.6 I must say it was more than excellent by 5.6 or 8 , but what is the point of designing a 1.4 if it's not usable, even stopping down (besides a nice clear view!) I sent it back to Carl Zeiss in Germany (the lens itself is made in Japan) but they returned it, after testing, saying it was within all tolerances. Well , there's the problem; their tolerances.... Anyway, I sold the ZE and now using my Summicron 2.0/50. It can slow you down a little, but besides that it operates great and image quality is known to everybody. NB! My expierence is only the 1,4/50. I really don't know about their Maco or Wide Angle lenses!! Mayby they are very good!! best to all herman Here is a new document from Zeiss about bokeh, for those who might be interested. http://www.zeiss.com/C12567A8003B8B6F/EmbedTitelIntern/CLN_35_Bokeh_EN/$File/CLN35_Bokeh_en.pdf All the best, Bill------ Unsubscribe or change to/from Digest Mode at: http://www.lrflex.furnfeather.net/ Archives are at: //www.freelists.org/archives/leicareflex/ ------ Unsubscribe or change to/from Digest Mode at: http://www.lrflex.furnfeather.net/ Archives are at: //www.freelists.org/archives/leicareflex/
