Sigma has introduced the Sigma BF, a 24.6 MP full-frame mirrorless camera designed to allow photographers to emphasize their creativity instead of dealing with complicated controls, thanks to its minimalist approach.
Innovative Design
The journey toward simplicity starts with a body crafted from a single piece of aluminum, marking a first in the camera world. The BF features a streamlined control scheme, consisting of just one dial and three pressure-sensitive haptic buttons at the back, alongside a shutter release on top. The 2.1 M dots screen primarily displays the live view, while a smaller monochrome status monitor positioned above the rear dial shows the chosen settings, like shutter speed.
Modern Functionality
Even with its straightforward design, the Sigma BF packs contemporary functionalities. The 35 mm sensor works hand-in-hand with a hybrid autofocus system that combines contrast and passive autofocus, capable of tracking both human and animal subjects in lighting as low as -5 EV, with an ISO range from 6 to 102,400. It supports full manual settings and offers 13 color modes, allowing for image capture as 6,016 x 4,012 pixel 14-bit RAW or JPEG files at a speed of up to 8 frames per second.
Video Capabilities
For videographers, this camera can record electronically-stabilized 6K and 4K footage at a frame rate of up to 29.97 fps, and 2K videos at rates as high as 119.88 fps. Videos with stereo sound can be saved in H.264, HEVC H.265, or L-Log formats onto 230 GB of built-in storage. In video mode, the camera’s base ISO is set at 1,250. Users can also activate a selectable histogram, zebra pattern, and false color monitors to help with video exposure settings.
Specifications and Compatibility
The dimensions of the camera are 130.1 x 72.8 x 36.8 mm (5.1 x 2.9 x 1.4 in.) and it weighs 446 g (15.7 oz.) including the battery. It is compatible with L-Mount lenses, featuring nine updated Sigma I series prime lenses ranging from 17mm to 90mm, which have been re-released with new color options and product names but maintain the same optical performance.
Availability and Pricing
The Sigma BF is set to launch in April 2025, available in black or silver colors, with a projected MSRP of $1999.
