Sigma BF Mirrorless Camera (Silver)

The Sigma BF’s forward-looking physical design concentrates all controls into just three buttons: a dial, a shutter release, and a power button. A rear dial pad allows further navigational control. All of these physical controls are pressure-sensitive haptics-driven, giving the user intuitive response to their touch. The camera also features a first-of-its-kind “unibody” build, as each camera is carved from a single block of aluminum, yielding a balanced, uniform weight distribution. A thumb grip in the upper right corner adds a small but crucial ergonomic element for handling the camera.

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.
