Sigma BF Camera Body Silver L-Mount

Close to the photographer, the Sigma BF captures the beauty hidden in everyday life and becomes the catalyst for awareness of that beauty.

The Sigma BF focuses on the joy of photography that a camera can provide as a tool. By simplifying and eliminating all unnecessary elements, this full-frame mirrorless camera redefines the process of shooting as a natural act.

The unique user interface, which offers a new sense of connection between photographer and camera in a true one-piece body, is more intuitive than ever thanks to its pressure-sensitive haptic dials and buttons.

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 features a completely new information organization compared to conventional digital cameras, with
the main shooting-related settings located on the live view screen, the secondary settings in the option menu, and the management functions and detailed settings in the system menu. Users can easily control shutter speed, aperture, ISO sensitivity, EV exposure compensation, and color mode, as well as other important shooting-related items, with the touch of a finger. Combined with the automatic setting, the functions of the general shooting mode dial are also available.

Live view and precise status screen
The default live view screen displays only the minimum information needed and can be changed to display no information at all. Since the current setting is displayed on the status screen, the user can concentrate solely on the composition and subject on the LCD screen.

Minimal Controls and HapticsAll controls are integrated into just three buttons, a dial, shutter release, and power button. The Sigma BF is the first mirrorless camera* to integrate haptics into its dial, center button, option button, and playback button, allowing for minimal physical input. The buttons are still precise and comfortable.

Monobloc Structure
The Sigma BF is the first camera in history* to feature a true monobloc structure, giving it unprecedented rigidity. Each camera is sculpted from a single block of solid aluminum for seven hours. This monobloc camera features a weight distribution that harmonizes perfectly with any lens.

Internal Memory
The Sigma BF features 230GB of internal memory, capable of storing over 14,000 JPEG files, 4,300 uncompressed RAW images or 2 hours and 30 minutes of video at the highest quality setting, with the USB-C port providing fast charging and data transfer speeds.

Various Colour Modes
Thirteen different colour modes are available to open up new avenues for creativity. These modes range from unique options such as Teal and Orange, Powder Blue and Warm Colour to creative and versatile options such as Vivid and Soft.

Advanced Autofocus
A hybrid autofocus system combining phase detection and contrast detection uses the latest generation of algorithms to capture subjects accurately and reliably. In addition to people, dogs and cats can be detected in subject detection mode.

Video Shooting (6K, L-Log)
The Sigma BF supports high-resolution 6K and L-Log recording, allowing you to produce videos that take advantage of the wide dynamic range of the full-frame sensor.

Equipped with an L-Mount
The L-Mount lens mount allows the camera to be used with a wide variety of interchangeable lenses for mirrorless cameras from Sigma and other L-Mount Alliance partners.
