Overview

The Leica SL (Typ 601) represents Leica's entry into the professional full-frame mirrorless market, and it does so with the brand's signature emphasis on build quality, image rendering, and optical excellence. At its core is a 24-megapixel full-frame CMOS sensor paired with the Maestro II image processor, a combination that produces images with rich tonal depth, natural color, and impressive dynamic range. The standout feature is the 4.4-megapixel electronic viewfinder — at the time of its release, it was the highest-resolution EVF on the market, and it remains remarkably sharp and immersive, making manual focus work a genuine pleasure.

For video shooters, the SL records DCI 4K (4096 x 2160) at 24 fps internally, delivering cinema-standard resolution without requiring external recording equipment. The ISO range stretches from 50 to 50,000, providing usable results in demanding low-light situations. The 2.95-inch touchscreen on the rear offers intuitive menu navigation and touch-to-focus functionality. Built from a single block of aluminum with full weather sealing, the body is designed to withstand professional use in challenging conditions. The camera uses the Leica L-mount system, which has expanded considerably through the L-Mount Alliance with Sigma and Panasonic, broadening the lens options available to SL shooters at various price points.
