Sigma BF (body) black L-mount

With the Sigma BF, we present an uncompromising new vision for the digital camera. Stripped to the essence but packed with power, innovative yet rooted in the origins of photography, it is designed to accompany you throughout your day and to capture the spontaneous beauty of everyday life. The BF balances performance with simplicity and returns the focus to what matters most: your photographs.

The Sigma BF’s most important feature is its simplicity. We wanted to create the easiest camera to use, inspired by the humble beginnings of the camera obscura. While the lens remains the soul of photography, the camera still profoundly shapes the images you take – directly, indirectly, even subconsciously. Without compromising on features or performance, the BF’s design cuts out everything that distracts from your interaction with the image. From its aluminum unibody to its simplified controls and streamlined menu, the BF embodies a pure photographic experience free of frustration.

Performance

A 24.6MP full-frame, backside-illuminated CMOS sensor powers the camera's high-end imagery. The camera has a wide dynamic range, a native ISO sensitivity of 100-102400 expandable on the low end to ISO 6, and the large sensor which benefits both low-light performance and low depth-of-field effects. Continuous shooting is possible at up to 8 fps, and the camera produces 14-bit DNG lossless RAW files in addition to JPEGs. A hybrid phase detection and contrast detection autofocus ensures quick and accurate focusing. Additionally, remote shutter release is possible with the optional CR-51 cable release.

Internal Storage

One of the notable features of the Sigma BF is its 230GB of internal storage, translating to more than 14,000 JPEG files, 4,300 uncompressed RAW files, or 2.5 hours of video. Additionally, a USB-C port offers data-transfer speeds of 10 Gb/s for external storage.

Video Capabilities

The Sigma BF can record video in up to 6K 30 fps and reaches up to 120 fps when shot in Full HD. The camera also supports L-Log color grading and HVEC encoding. Electronic image stabilization is supported when shooting video, benefitting smooth footage capture, and on a full battery the camera can record continuously for an hour. A built-in microphone atop the camera captures stereo sound, with support for an external microphone or headphone output. The USB-C terminal also allows users to output video and use the Sigma BF as a webcam.

L-Mount Compatibility

Sigma is a member of the L-Mount Alliance, and the BF's L-mount for lenses affords users access to the broad range of high-quality lenses from Samyang, Sigma, Panasonic, and Leica.
