Leica's new 50 mm f/1.4 Summilux is 45% lighter, €1,550 cheaper

The new Summilux-SL 50 mm f/1.4 ASPH. aims to change that. With a length of 7.55 cm, a diameter of 7.4 cm, and a weight of 584g, the lens is said to be the smallest of its kind. These more compact dimensions are made possible by a completely new optical design featuring eleven elements in six groups, as well as improved manufacturing processes, and the lens is still “Made in Germany.” The minimum focusing distance has been reduced from 0.6 to 0.5 meters, and the filter diameter has shrunk from E82 to E67.

Leica also hints that the autofocus motor and splash protection have been improved, though it does not provide specific figures. The new Summilux replaces the previously available model in Leica’s lineup. As the comparison of the MTF charts embedded below shows, however, the significantly smaller dimensions also mean that the lens no longer produces images quite as sharp at wide-open aperture as its predecessor did.
