pgk Posted March 19, 2020 Share #2  Posted March 19, 2020 Welcome. I would try posting this in the Leica Collectors & Historica section where you are more likely to get a helpful response - or ask a moderator to move it for you. Link to post Share on other sites More sharing options...

luigi bertolotti Posted March 19, 2020 Share #4  Posted March 19, 2020 Here's the glass schema of Fat Elmar : classic 4 element Elmar design quite similar to 35 - 50 - 135 ; unchanged for many years, with variations in lenses' curvatures and probably glass formulas ; "stripped" to 3 elements in the last series of Elmar 90.
