This new lens is quite modestly priced for a Leica, certainly compared to the 24-90/2.8-4.0; could it be based on the Sigma 24-70 DN Contemporary or even the Panasonic 24-70 which it is priced quite close to. Odd move by Leica. Do SL/SL2 owners feel they have to have Leica lenses or do some mix Leica, Sigma and Panasonic lenses?
