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.
