Every camera released in the last decade looks roughly the same: a black rectangle bristling with dials, buttons, and ports. The Sigma BF doesn’t. It has three controls - a shutter release, a dial, and a power button - all pressure-sensitive haptics rather than mechanical clicks. The body is machined from a single block of aluminium over seven hours. No seams, no panels, nothing to rattle loose.
The sensor is a 24.6MP full-frame BSI CMOS without an anti-alias filter, native ISO to 102,400, and the camera shoots 6K video with L-Log support. The SD card slot is gone entirely, replaced by a 230GB internal SSD: enough for 4,300 RAW files or two and a half hours of top-quality video, offloaded fast through USB-C. The L-Mount means you have access to the full Sigma, Panasonic, and Leica lens ecosystem.
What Sigma is arguing with the BF is that the modern camera has accumulated complexity it doesn’t need. The haptic buttons feel immediate without mechanical wear. The 3.15-inch touchscreen handles the rest. Shooting with it forces a certain intentionality: you can’t tweak seventeen settings mid-shoot because they’re not there to tweak. Whether that’s a feature or a flaw depends on how you work.
At £1,869 it’s a meaningful investment for something that deliberately does less. But it does what it does with unusual conviction, and nothing else looks remotely like it.
