If you're going to go all out on a camera and we mean ALL OUT then you probably should look no further than Alpa. The Swiss company's cameras are built with the kind of precision reserved for the finest of watches and their latest model continues that theme with the Alpa 12 Plus. Carefully milled from an entire aluminum block, the camera is incredibly adjustable with details like brass shift guides and is optimized for use with digital backs, though a film back can be partially used with an adapter tube.
