– New Summilux-SL 50mm is significantly smaller and lighter (584g vs 1,065g).
– Reduced minimum focus distance (0.5m vs 0.6m) and smaller filter thread (E67 vs E82).
– Slightly less sharp wide-open than its predecessor despite new optical design.
– Improved autofocus and splash protection, but no specific data provided.
– Priced at €4,500 (€1,550 cheaper) with a late 2026 release.
The Leica Summilux-SL 50 mm f/1.4 ASPH. is now already a decade old. While the lens still offers competitive image quality, at 12.4 cm long, 8.8 cm in diameter, and weighing 1,065g, it is larger than most of its direct competitors. Many photographers have stuck with it due to its rendering but the size was always a compromise for travel.
New Dimensions and Optical Design
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. This makes it a fair bit smaller for everyday carry.
Performance and Build Updates
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. This might disappoint some pixel peepers but for most it will be fine.
Pricing and Release Timeline
The new Leica Summilux-SL 50 mm f/1.4 ASPH. is expected to be released in late 2026 at a suggested retail price of €4,500. This makes the lens €1,550 cheaper than its predecessor. Its a significant price drop for a Leica product wich is unusual in there lineup. Many will find this attractive despite the slight sharpness trade-off.
