The 75mm focal length provides a slight telephoto perspective suitable for portraiture and editorial photography. The APO-Summicron-SL line is Leica's highest optical quality tier for the SL system.
On the used market the Leica APO-Summicron-SL 75mm f/2 ASPH is available at Leica SL premium prime pricing. Condition checks: AF response, 67mm front element for marks. Compatible with all L-Mount bodies: Leica SL/SL2/SL2-S, Panasonic S, Sigma FP/FP L.
