An intuitive tool designed to radically simplify imagemaking, the 24.6MP full-frame Sigma BF Mirrorless Camera (Silver), reimagines the high-end digital camera interface to emphasize ease of use. The L-mount, hybrid-AF body also boasts 6K video capabilities, resulting in a camera that produces high-quality imagery at will.
The Sigma BF marks a turning point in mirrorless camera design. Every point of user interface from body to screen has been reconceived to streamline the image creation process, allowing users unprecedented access to the beauty unfolding in front of the lens.
The primary user interface of the live-view rear touchscreen has been redesigned with shooting in mind, where shooting-related settings like shutter speed, aperture, ISO sensitivity, EV compensation, and color mode all find their natural home. The live-view itself has been streamlined to allow shooters maximum focus on their subject.
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 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. A hybrid phase detection and contrast detection autofocus ensures quick and accurate focusing.
The Sigma BF can record video in up to 6K 30 fps and reaching up to 120 fps when shot in Full HD. The camera also supports L-Log color grading and HVEC encoding.
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 fast data-transfer speeds for external storage.
The Sigma BF comes pre-loaded with 13 different Color modes, allowing users to apply color filters to their imagery for expanded creativity.
