Sigma Unveils Minimalist BF Full-Frame Camera with Built-In SSD

The $1,999 camera features a sleek unibody aluminum design, simplified controls, and 230GB of internal storage, launching in April 2025.

The Sigma BF is a 24.6-megapixel full-frame mirrorless camera with a minimalist design and no memory card slot, relying instead on a built-in 230GB SSD.
Its unibody chassis is carved from a single block of aluminum over seven hours, making it the first camera of its kind to feature such a design.
The BF emphasizes simplicity with just four touch-sensitive controls, a single dial, and a fixed 3.15-inch touchscreen, prioritizing an intuitive user interface.
Photographers can directly access key settings like shutter speed, aperture, ISO, EV compensation, and color modes without traditional dials or cluttered menus.
The camera is compatible with L-Mount lenses and supports 6K video recording, but lacks a viewfinder, articulating screen, and audio input/output options.
