gtownby Posted February 3, 2021 Share #1  Posted February 3, 2021 Advertisement (gone after registration) I noticed in the specs that the SL 24-90mm f/2.8-4 Vario-Elmarit ASPH has 11 elements (out of 18) with anomalous partial dispersion glass. Yet Leica does not advertise this as an "APO". I recall that the M 50mm f/1.4 Summilux ASPH also has "APO" glass but Leica chose to not promote it as such. I know this is a bunch of "angels dancing on the head of a pin" - but any thoughts on this? Link to post Share on other sites More sharing options...
