ULTIMATE IN MINIMALISM

SEAMLESS INTERACTION

The Sigma BF represents a new, more intuitive way to use a camera. It is streamlined to make the act of photography as effortless as possible. We have replaced the shooting mode dial – itself a holdover from the days of film photography – with direct access to the five elements that decide the photograph. Shutter speed, aperture, ISO, EV compensation and color mode are all immediately available at the touch of a finger. The new Status Monitor displays the currently active setting, so the screen provides an unobstructed view of the subject. 

CLEAR VIEW


The BF's high-resolution screen provides a distraction-free view of all necessary information – and nothing more. With one simple setting, it shows only the live view image, with the five key elements – shutter speed, aperture, ISO, EV compensation and color mode – displayed when you are ready to press the shutter button. All other options and settings are accessed via just three simple menu screens.

AT A GLANCE


The innovative Status Monitor displays the active setting, highlighting exactly what you need to know without distraction.

TACTILE CONTROL

 

With just three buttons and a dial pad, the BF’s redesigned user interface makes adjustments instant and intuitive, leaving your attention on the scene and not the settings. As the first mirrorless camera*, the BF features pressure-sensitive haptic buttons, resulting in minimal physical wear while still offering the precise and tactile sensation of conventional mechanical buttons.

*As of February, 2025 by Sigma.

ENDURING FORM

The BF is designed to last. It is the first camera in history* to feature a true unibody, with each camera carved from a single, solid block of aluminum ingot over the course of seven hours. The weight of its seamless all-metal body harmonizes perfectly with any attached lens, while its shape, button placement and precision-cut front texture guarantee secure handling.

*As of February, 2025 by Sigma.

DECEPTIVELY POWERFUL

Simplicity does not mean limitation. The Sigma BF is packed with advanced technology to expand your creative possibilities. Its powerful full-frame sensor delivers exceptional image quality, while the fast, reliable hybrid autofocus system keeps subjects in focus.

HIGH RESOLUTION VIDEO

 

Some stories are best told in moving images. With 6k recording, powerful HEVC encoding, L-Log support and up to 120 frames per second, the Sigma BF provides filmmakers with a nimble, versatile camera to capture and refine their vision.

FULL-FRAME SENSOR

 

The BF's 35mm full-frame sensor means stunning details, exceptional image quality, wide dynamic range and brilliant low-light performance. The large sensor size also translates to a shallower depth of field to separate subject and background, and allows the use of high-quality full-frame lenses.

INTERNAL STORAGE

 

The SD card slot is replaced by 230GB of internal memory, capable of storing more than 14 000 JPEG files, 4 300 uncompressed RAW images or 2.5 hours of video at the highest-quality setting, with the USB-C port offering fast charging and data-transfer speeds. 

CAPTURED WITH THE BF

The cameras we make are only part of the photographic story. What really counts are the wonderful images that photographers create with them.

We invited Ola Rindal, Fumi Nagasaka, and Sarah van Rij & David van der Leeuw to produce new work with the Sigma BF. Each artist captures the subtleties of everyday moments with their unique perspective and visual language. We hope you enjoy their photos as much as we did.
