Description

Beauty is Radically Simple

An intuitive tool designed to radically simplify image making, the 24.6MP full-frame Sigma BF Mirrorless Camera, 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.

Sleek, Intuitive Design

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.

Streamlined UI

The primary user interface of the live-view rear touchscreen has been redesigned for distraction-free shooting, where exposure 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, while a small status monitor above the rear dial pad clearly displays the active settings. All other options and settings are accessible via three simple menu screens.

Physical Design

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.

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 Sigma, Panasonic, and Leica.

Color Modes

The Sigma BF comes pre-loaded with 13 different Color modes, allowing users to apply color filters to their imagery for expanded creativity: Standard, Rich, Calm, Powder Blue, Warm Gold, Teal and Orange, FOV Classic Blue, FOV Classic Yellow, Forest Green, Sunset Red, Cinema, 709 Look, and Monochrome.
