The Sigma fp Mirrorless Digital Camera delivers high-spec functionality for stills and video in an extremely compact body that weighs under one pound. Driven by a full-frame 24.6MP BSI Bayer CMOS sensor, 14-bit color depth, electronic image stabilization, and Leica's L-mount lens interface, the fp and its fully electronic shutter provide a maximum resolution for raw and JPEG files of 6000 x 4000 and a shooting rate of 18 fps, while its focus system employs contrast detection and a 49-point selection mode for AF measurement distance, as well as face detection, eye detection, and focus peaking. A base sensitivity of ISO 100-25600 can be expanded to ISO 6-102400, and its video recording capabilities allow for UHD 4K recording at up to 30p, while Full HD recording can be captured at up to 120p. For raw video data, 12-bit CinemaDNG external recording is supported. To help shooters fine tune their video content, Sigma's "Teal and Orange" mode is inspired by the color grading techniques of Hollywood and creates high contrast between orange colors, which are found in human skin tones, and teals (cyan blue), which are their complement. So that users may easily switch between still and video modes, there is a switch on top of the camera.

Also available for video shooters in a "Director's Viewfinder" function, which allows for the simulating of different angles of view and how an image looks in a cinema camera. It supports cameras such as the ARRI ALEXA LF and RED MONSTRO 8K, as well as other commonly-used digital cameras, film cameras, and anamorphic lenses.

Compose and review your shots with a 3.15" 2.1m-dot LCD touchscreen, and media is captured internally to a UHS-II SDXC card slot. Thanks to an effective heat sink and a 42-point seal for dust- and splash-proofing, the fp will function well for long hours of use in a wide variety of environments. If you need to connect to external peripherals, there is a USB 3.1 Gen 1 Type-C port and a micro-HDMI port.
