Leica's L-Mount super-telephoto zoom — 100-400mm with Leica optics for the SL system.
The Leica Vario-Elmar-SL 100-400mm f/5-6.3 is Leica's super-telephoto zoom for the L-Mount system. It provides 100-400mm reach with Leica's optical quality standards, targeting wildlife and sports photographers within the Leica SL and L-Mount Alliance ecosystem.
Optically good — sharp in the centre throughout with Leica's characteristic contrast and colour. The variable f/5-6.3 aperture is relatively slow but typical for this focal range. Autofocus is adequate. Image stabilisation via OIS built into the lens.
L-Mount with 72mm filter thread. Approximately 1160g. Weather-sealed construction. Tripod collar included. Compatible with Leica SL, Panasonic S, and Sigma fp bodies via L-Mount Alliance. 1.4x extender compatible.
Available used at luxury prices. The Sigma 100-400mm f/5-6.3 DG DN OS offers similar optical quality at a fraction of the cost for the same L-Mount system. The Leica premium is primarily build quality and branding. For Leica SL system owners wanting a matched telephoto zoom.
