Just kidding. Â I also don't believe that Scientists discovered Higgs Boson. Â Not that Cicala is a scientist but I don't understand the methods of both his and the guys at CERN. It is true. Â BTW, has he been challenged on LensRentals about this? Â ...and I found bunch of other interesting articles. https://www.lensrentals.com/blog/2016/09/fun-with-field-of-focus-part-1/ Edited March 1, 2018 by jmahto Link to post Share on other sites More sharing options...
jaapv Posted March 1, 2018 Share #63 Â Posted March 1, 2018 12 mm is quite usual in lens measurements. Actually, Rogers figures may be quite correct. @ 100% contrast the MTF curve of the Summicron is completely flat up to 12 mm. (See Erwin Puts Leica Compendium).
