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.

Sigma's CEO says BF unofficially stands for 'beautiful foolishness,' a nod to Japanese tea ceremonies. Indeed, the camera leaves a lot of stuff out, including features enthusiasts may miss.

If you're going to compare the BF to anything, it should be the iconic Leica TL – a similarly breathtaking camera, similarly machined from a single ingot of aluminum and similarly "smooth" to shoot with. Because make no mistake, whatever else this camera promises, the way it looks and the way it operates will always come first.

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

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.
