luigi bertolotti Posted June 10, 2007 Share #1 Posted June 10, 2007 Advertisement (gone after registration) I am a longtime user of M4, and also a passionate collector of lenses; as a user, I shot film most with the standard 28-35-50-90-135 set (35 & 90 preferred); so when 3 weeks ago I received my M8, my idea was to use as possible my present lenses (all aged, but most of them excellent) so I only bought a LN 21 asph that went for coding: besides this: - My Elmarit 28 pre asph is (apart the 21) my youngest lens, is codable, I plan to have it coded and already verified it focuses right. - My Tele Elmarit 90 is very old (1st, chrome) but seems perfect on M8: I experienced a strong case of "magenta cast" but in the meantime the filter has arrived... The problem is with 35 and 50 : I read here the problem of backfocusing, and today arranged a (hope) precise test using a newspaper with 35s at 1,2 m and 50s at 1,6 m: ISO 160, RAW, lenses 1 stop closed (is stupid, but I hate to shot wide open in real use); I feel happy for both the 50s (Cron & Lux) seem not to have significant problems of focus, but I really like to receive some insight by people of the forum : following are the test picture and two 100% crops from Summilux and Summicron (BTW, made the same with an Elmar at f4: focus Ok, worst definition of small letters). Things complicated with 35s, my Summilux 1st type was not satisfactory, the Summicron 1st type and the Summaron 2,8 do not definitely focus right: after the above "50s" I attach the image and the 100% crops of Summilux, Summicron 2nd type and Summaron 3,5 : your comments are very welcome: I have to decide which of mine 35s and 50s I'm going to use on M8 Link to post Share on other sites More sharing options...
