fernando_b Posted March 19, 2007 Share #1 Posted March 19, 2007 Advertisement (gone after registration) I brought months ago - from our sponsor Amazon.com - the 7th edition of Leica pocket book. Received it saturday and found it well done. There is however something of not clear. Someone know how the shown MTF curves have been obtained? I suspect at least one of them is wrong. Fernando.

fernando_b Posted March 20, 2007 Author Share #4 Posted March 20, 2007 Duncan, I was pointing at the R180/2.8 2nd version (non APO). I've seen it tested by a lab that usually tests aerospace optics and the results are much different! So I have some suspect about the published curves. Fernando.
