The Leica S2 camera is a professional medium format digital camera produced by Leica Camera AG. It was first introduced in 2008 and represents Leica's foray into the medium format market. The S2 is designed to deliver exceptional image quality and is targeted towards professional photographers who require high-resolution images and precise control over their photography.

The Leica S2 features a large 37.5-megapixel (30x45mm) CCD sensor, which is significantly larger than those found in typical full-frame DSLRs. The camera employs the Leica S-System lens mount, specifically designed for the S-series cameras, which offers a range of high-quality lenses optimized for the large sensor size.

In terms of construction, the Leica S2 boasts a robust and weather-sealed body, constructed from a combination of magnesium alloy and high-quality materials. It features a comfortable ergonomic design with intuitive controls and a large, bright optical viewfinder for accurate framing and composition.
