The Sigma BF features simplified controls on the back, a redesigned user interface, and 230GB of built-in storage.

The Sigma BF looks like a luxury tech company’s bid to enter the imaging industry. Either that or a prop from 2001: A Space Odyssey – I’ve never seen a full-frame camera like it!

The BF has 230GB of internal memory instead of any removable media cards and uses the USB slot to transfer data off the camera. Sigma says this is sufficient for 14,000 JPEGs, 4300 uncompressed DNG Raws or 2.5 hours of video shot in its highest quality settings.

That’s according to PetaPixel, which during a tour of Sigma’s Japanese HQ, was told that making the Sigma BF’s aluminum housing requires seven hours of milling by two machines. That amounts to a production output of about nine cameras per day.

It’s less minimalist on the inside, although to maintain that sleek look Sigma has opted for 230GB of internal storage instead of using memory cards, which might put some shutterbugs off, but should be enough to store around 14,000 JPEGs captured by the 24MP full-frame sensor.

Sigma has unveiled the Sigma BF, a new mirrorless offering that represents the brand’s uncompromising new vision for the digital camera. Rooted in the origins of photography yet innovative in design, the BF is intended to accompany users throughout their day, capturing the spontaneous beauty of everyday life.

Sigma has introduced its latest full-frame camera called the BF, which features a minimalistic design and doesn't offer a memory card slot.
