Leica's fast 50mm for SL system — Summilux f/1.4 with AF for L-Mount professional use.
The Leica Summilux-SL 50mm f/1.4 ASPH. launched in 2014 alongside the original SL as the system's fast normal prime. The Summilux-SL designation indicates f/1.4 with Leica's ASPH correction — the premium fast 50mm for L-Mount.
Optically outstanding — Leica Summilux quality at f/1.4 with aspherical correction. Autofocus with Leica's dual-synchro-drive — the first AF Summilux. L-Mount provides access to Panasonic and Sigma bodies via the Alliance.
L-Mount with weather sealing. Approximately 1065g — very heavy for a 50mm. All-metal premium construction. AF with Leica's drive system. L-Mount Alliance compatible. Minimum focus distance 50cm.
Available used at professional to luxury prices. The weight is the main practical concern — 1065g makes this one of the heaviest 50mm primes available. The Sigma 50mm f/1.4 DG DN Art is lighter and sharper for much less. For Leica SL system purists wanting the matched Summilux experience.
