About This CameraThe Sigma BF is a 24MP full-frame mirrorless camera offering distinctive design and unconventional user interface. It is an idiosyncratic camera where every aspect of its design is both innovative and clever. Explicitly designed for 'everyday' photography as an elegant object to carry with you. It is not trying to be a do-everything camera, as Sony's a7C II exists at a similar price point with more features. | |
