The Leica S (Typ 007) is a medium format DSLR offering high-resolution still and video recording capabilities. Revolving around a 37.5MP 30 x 45mm CMOS sensor and Maestro II image processor, this camera is notable in its ability to produce image quality with remarkable sharpness, clarity, and dynamic range. The omission of an optical low-pass filter from the sensor's design further enables enhanced detail and resolution, that pairs well with the optimized Leica S lenses. Furthermore, on-sensor microlenses work to produce consistent and even light distribution to ensure edge-to-edge sharpness and illumination for a high degree of overall clarity. Beyond advanced still image recording, the S is also capable of producing 4K video files, as well as full HD, with a variety of options for audio and video recording. Utilizing the large sensor to the fullest extent, the S (Typ 007) is a versatile imaging device designed to deliver the utmost quality to both photographers and videographers.

Combining the sensor and processing prowess of the camera, a top sensitivity of ISO 12500 is afforded as well as the ability to record up to 32 consecutive DNG files at a rate of 3.5 fps. A predictive autofocus system, using a central cross-type phase-detection point, helps to maintain critical focus in a variety of lighting conditions. Additionally, if working in a live view, focus peaking serves as a useful alternative for ensuring image sharpness with manual focus techniques.

Complementing the advanced imaging capabilities of the Leica S is an equally refined body design, which takes on a minimalist structure with a focus on the most essential shooting controls. A large, 3.0", 921.6k-dot, LCD monitor serves as a clear means for image review and menu navigation while the large 0.87x-magnification, pentaprism viewfinder acts as a bright tool for image composition. A weather-sealed, magnesium alloy, body construction protects the system from dust and moisture, including the series of interface ports and lens mount. Additionally, built-in Wi-Fi connectivity enables remote camera control and wireless transferring of files to mobile devices, and a GPS module enables the recording of location information to the EXIF data of image files.
