    The world's smallest and lightest “pocketable full-frame” camera is here.

    Impressive portability and power

    With overall dimensions of 4.4" x 2.75" x 1.8" (112.6×69.9×45.3mm) and a body weight of 13oz (370g), the SIGMA fp is the world's smallest and lightest interchangeable lens camera equipped with a full-frame sensor. Sigma fp employs a back-illuminated 35mm full-frame image sensor with 24.6 effective megapixels and a full-time electronic shutter, enabling to shoot virtually without sound, and no camera shake due to shutter shock. Even when shooting in quick succession at a frame rate of 18 frames/sec., it eliminates the tiniest of shakes. In addition, as opposed to conventional mechanical shutters, it does not cause irregularities on the screen display in a high-speed shutter setting.

    Furthermore, the absence of a mechanical shutter makes the SIGMA fp's camera structure simpler, which in turn improves its reliability.

     HDR Shooting

    The environment that surrounds shooting and art creation is undergoing radical changes. In this day and age when one user may have both a high-performance interchangeable lens camera and a smartphone camera, using them flexibly according to specific purposes and settings, SIGMA stopped and questioned the inherent value of a digital camera.

    As a result, SIGMA set itself to develop a user-oriented digital camera that reflected the idea of “how a camera can be” in a more flexible and true-to-life manner, without conforming to manufacturers' ideas of camera-centric categories and hierarchy.

    fp Development Concept

    Pocketable Full-frame | Impressive portability and power

    The “smallest and lightest body possible” with which one can express their creative ideas whenever they want, combined with a “full-frame sensor” that is suitable for serious occasions without compromising on image quality, and “superb build quality” that makes the camera the perfect linchpin of a high-performance lens system.

    Scalable | Versatile scalability

    An “open system” that allows one to pair the camera with not only SIGMA lenses but also other lenses and accessories, whether from SIGMA or other brands, using a variety of attachments, complete with “ultimate versatility and scalability” that makes the camera adaptable to any scenes.

    Seamless | Full-fledged, liberating shooting functions

    A “highly intuitive UI” that allows one to move between full-fledged still and video shooting modes with just one finger, making for a “seamless and truly creative tool” that goes beyond style and genre differences.

    Making it a top priority to realize these three concepts all at once and without requiring any trade-offs, SIGMA selected only the elements and mechanisms that were truly needed with no compromise to create the SIGMA fp as the embodiment of an “entirely new digital camera that SIGMA can offer to the world right now.”

    It's a camera body that changes its shapes with great flexibility centered around the user.

    It's a tool that gives the user the joy of a new camera life that they themselves are yet to discover.

    It's a new system camera that will overturn the paradigm of “digital cameras.”

    The SIGMA fp is here to broaden the potential of “image shooting” ad infinitum.


    The SIGMA fp is the world's smallest and lightest full-frame mirrorless camera*. It employs a back-illuminated 35mm full-frame Bayer sensor with 24.6 effective megapixels for high-quality images. Covered on the front and back sides with die-cast aluminum alloy for its superior robustness and thermal conductivity, the compact body of the SIGMA fp is built with a signature heat sink structure and sealing on 42 points for a dust- and splash-proof structure, making it a perfect camera to use for long hours under all types of environments. With its small body and great adaptability, the SIGMA fp enhances the joy of full-frame image quality, no matter what one's shooting settings may be.

    * As of July, 2019.

    Full-frame sensor

    Equipped with a back-illuminated 35mm full-frame Bayer sensor with 24.6 effective megapixels, the SIGMA fp is capable of taking high-resolution still and moving images.

    Robust & lightweight aluminum body

    A body covered with die-cast aluminum on the front and the back ensures superior robustness and heat dissipation while keeping the body weight light.

    Large heat sink

    Designed and inspired by those used on professional cinema cameras, a large-size heat sink is mounted between the LCD and camera body. Combined with a heat dissipation coating applied to the outer surface, the SIGMA fp achieves highly effective heat dissipation. It prevents overheating at high temperatures or in long hours of use.

    Dust & splash-proof structure

    The SIGMA fp is protected with the dust- and splash-proof sealing on a total of 42 points over the camera body. When combined with a dust- and splash-proof lens, the SIGMA fp is capable of shooting in rain, sandstorms, and other challenging conditions.

    Same screw threads for strap fittings and tripod

    The SIGMA fp is fitted with 1/4-inch threads for both the strap holder on either side of the body and a tripod. This provides greater freedom in how one use the camera, from mounting it on a tripod in portrait orientation with the fixing removed, to attaching a strap for use in portrait orientation after screwing the fixing into the hole on the base.

    Full-time Electronic shutter for a variety of settings

    Shutter shock, sound, and lags: these are disadvantages of mechanical shutters. The SIGMA fp is designed to minimize them in pursuit of a system to adapt to a variety of different shooting scenes. Shooting that requires precision where even the tiniest shake is to be eliminated; shooting without ruining the ambience of the scene; and shooting with good response, without missing the perfect shot. These types of shooting will open new horizons in video creation.

    Furthermore, the absence of a mechanical shutter makes the SIGMA fp's camera structure simpler, which in turn improves its reliability as a camera.

    Superior options in artistic picture & video creations

    Color mode “Teal and Orange”

    Color grading is a process of altering the color of a video and is an important step in filmmaking that will change the “mood” of a film or other types of work significantly. One color grade style that has been widely used in Hollywood films has inspired a new color mode introduced in the SIGMA fp, called “Teal and Orange.”

    This new color mode is about creating high contrast between orange colors, which are found in human skin tones, and teals (cyan blue), which are their complement, for visuals that are highly vibrant and deeply dramatic.

    It can be used in both the Still mode and Cine mode.

    Fill Light

    A function formerly available only in SIGMA Photo Pro, SIGMA's proprietary image development software, Fill Light has now been incorporated into the body of SIGMA fp. Using Fill Light allows adjustment of the brightness of an image by adding extra light energy into the shadow regions without altering the exposure of highlight regions. This provides greater control in producing an image with great details, even with areas that are hard to control using the exposure adjustment settings.

    The adjustment range, which was formerly ±2.0, has been expanded to ±5.0, making it possible to fine-tune the brightness even more.

    * Still mode only

    Tone Control & Color mode

    The Tone Control menu now has a manual setting option in addition to the two auto options available in previous models (Strong/Mild), which allows users to adjust the tone curve by themselves.

    The SIGMA fp is also the first SIGMA camera to come with an "effect" slider in its color mode menu. It can be used to set the strength of an effect to apply in 11 levels, from -5 to +5, which enables the fine-tune of the color mode.

    It has also newly introduced "TONE" and "COLOR" buttons for a quick access to the tone control and color mode menus. With these enhancd functions and a variety of operation elements, the SIGMA fp makes it simple and easy to create an image, in-camera with great details, be it still or video.

    Advanced picture & video generating technologies

    HDR shooting

    The HDR shooting takes advantage of an electronic shutter to take multiple pictures of different exposures (3 frames for still photography and 2 frames for video) at once, which can then be merged into a single picture or video with a great dynamic range that could not have been achieved in normal shooting.


    SIGMA fp comes with a feature to make "Cinemagraph", which are animations that are a hybrid between still photography and video. With this function, the SIGMA fp is capable of creating unique imagery, where parts of a still image keep moving, in-camera.

    Face/Eye Detection AF

    The Face/Eye Detection AF function allows the SIGMA fp to focus automatically on the eyes of a human subject. It can bring the eyes of the model into focus instantly and precisely, even when shooting portraits using a large-diameter lens with a shallow depth of field.

    Focus peaking

    The focus peaking function highlights the edges of the parts of a scene that are in focus in a particular color. It is designed to help focusing the lens manually.


    L-Mount* is a mount optimized for mirrorless cameras, characterized by a short flange focal length, large diameter, and superior durability.

    In 2018, Leica Camera AG, Panasonic Corporation and SIGMA launched the L-Mount Alliance, and announced that the three companies were to develop their own camera systems based around the same L-Mount standard. As an L-Mount camera, the SIGMA fp can be used with various L-Mount lenses offered by Leica and Panasonic, in addition to SIGMA lenses.

    The L-Mount realizes a camera system that goes beyond the boundaries between manufacturers, with unprecedented levels of scalability and possibilities.

    * The L-Mount Trademark is a registered Trademark of Leica Camera AG.

    Supports full-fledged filmmaking

    Accessories and compatibility

    In addition to genuine accessories designed exclusively for the SIGMA fp, the camera supports cinema camera-like user interfaces. It has solid compatibility that makes it a perfect camera that fits right into filmmaking settings.

    Supports RAW video data recording

    Aside from professional cinema cameras, the SIGMA fp is the first interchangeable-lens mirrorless type digital camera that supports external recording in 12-bit CinemaDNG format. With up to 4K UHD/29.97fps recording, it produces video data that can be used even in filmmaking.

    It also supports All-I (All-Intra) recording, which makes it possible to maintain high image quality while reducing file size, allowing light data available for recording and editing. The record format that best suits the purpose of the video can be selected.

    * The feature of playing CinemaDNG footages in-camera is to become via firmware update scheduled at a later date.

    * The CinemaDNG logo is either a registered trademark or trademark of Adobe Systems Incorporated in the United States and/or other countries.

    Director's viewfinder

    The SIGMA fp has a director's viewfinder function that allows the user to simulate different angles of view and how an image looks, on cinema cameras. It supports cameras by major manufacturers commonly used in filmmaking. It supports not only the latest large format cameras such as ARRI ALEXA LF and RED MONSTRO 8K but also filmcameras and anamorphic lenses as well.

    Cinema cameras supported:







    Special functions comparable to professional cinema cameras

    The SIGMA fp's Cine mode comes with a variety of special functions that are comparable to those of professional cinema cameras. From shutter angle display and waveform display for exposure and color information, to zebra patterning, it comes with the functions and screen displays that can be used in the same way as with conventional cinema equipment.

    Seamless transition between Still and Cine modes

    UI optimized for different shooting modes

    Preserving the distinctive “feels” of SIGMA cameras including dials and QS (Quick Set) buttons, the SIGMA fp has a specially designed operation system and displays for each of the Still mode and the Cine mode. At the flick of a special switch, it can move back and forth between the two modes. This presents a new shooting experience that goes beyond the boundaries of traditional cameras that are designed either for stills or videos.
