A radically simple camera that evokes the essence of photography

A full-frame mirrorless camera offering an unprecedented intuitive shooting experience

Staying close to the photographer, the Sigma BF captures the beauty that lies hidden in everyday life, and becomes the catalyst to be aware of that beauty. The BF focuses on the joy of photography that a camera as a tool can provide. By simplifying and stripping away all excess elements, this full-frame mirrorless camera redefines the process of taking a photograph as a natural act. The unique user interface, which provides a new sense of connection between the photographer and the camera in a true seamless unibody, is more intuitive than ever with its pressure-sensitive haptic buttons and dial. The high definition expression of the approximately 24-megapixel full-frame sensor and the reliable dual autofocus system bring your vision to life.

Simple, clear, and completely new user interface

The user interface has a completely new information structure compared to conventional digital cameras, with the main shooting-related settings stored on the live view screen, secondary settings in the optional menu, and management functions and detailed settings in the system menu. Users can easily operate the shutter speed, aperture, ISO sensitivity, EV compensation and color mode, along with other important shooting-related elements at the touch of a finger. Combined with the auto setting, the functions of the general shooting mode dial are also covered.

Clear live view and status monitor

The default live view screen displays only the minimum necessary information and can be changed to display no information at all. Since the currently active setting is displayed on the status monitor, the users can concentrate solely on composition and the subject on the live view screen.

Minimal controls and haptics

All controls are integrated into just three buttons, one dial, the shutter release, and the power button. The BF is the first mirrorless camera to incorporate haptics into its Dial, Center button, Option button, and Playback button, resulting in minimal physical wear. The buttons are always accurate and comfortable to press.

Unibody structure

The BF is the first camera in history* to feature a true unibody, which boasts unprecedented rigidity. Each camera is carved from a single, solid block of aluminum ingot over the course of seven hours. The reliable, comfortable weight of its seamless all-metal body harmonizes perfectly with any attached lens.

Internal storage

The BF features 230 GB 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.

Small in size, big on quality. Perfect for carrying anywhere.
