Leica's video-optimised L-Mount mirrorless — 24.6MP BSI sensor, 5K video, Dual ISO, IBIS.
The Leica SL2-S was released in December 2020 as the video-optimised variant of the SL2, using a 24.6MP full-frame BSI CMOS sensor optimised for higher video frame rates and lower-light performance rather than the SL2's 47.3MP resolution. 4K/60fps and 5K video are available. 5-axis IBIS provides approximately 5.5 stops of stabilisation. The L-Mount provides full compatibility with the Leica, Panasonic LUMIX S, and Sigma FP lens ecosystems. Body weight approximately 850g.
The 24.6MP full-frame BSI CMOS sensor is optimised for video frame rate and low-light performance. 5-axis IBIS provides approximately 5.5 stops of compensation. 4K video records at up to 60fps; 5K video is available. L-Mount native communication for full IBIS coordination with L-Mount lenses. BP-SCL4 battery — shared with the Leica Q2. Body weight approximately 850g without battery and card.
The SL2-S's lower 24.6MP resolution versus the SL2's 47.3MP reflects the video-first design: lower pixel count reduces data rate and heat output for sustained 4K/60fps recording, and improves rolling shutter at high frame rates. The 5.5-stop IBIS enables handheld video in low-light conditions without gimbal stabilisation. For Leica system photographers who prioritise cinema-quality video and documentary work over maximum still resolution, the SL2-S is the practical choice over the SL2.
On the used market the Leica SL2-S commands a significant premium reflecting the Leica L-Mount system positioning. Condition checks: IBIS operation, BP-SCL4 battery health — shared with the Q2 and SL2 — weather sealing at port covers, and EVF display quality. L-Mount lens compatibility spans Panasonic LUMIX S, Sigma FP/FP L, and all Leica SL lenses. Leica M lenses are compatible via the M-Adapter L.
