THE BF CAMERA

THE BEAUTY OF A SIMPLE THING

RADICAL SIMPLICITY

The Sigma BF’s most important feature is its simplicity. We wanted to create the easiest camera to use, inspired by the humble beginnings of the camera obscura. While the lens remains the soul of photography, the camera still profoundly shapes the images you take – directly, indirectly, even subconsciously. Without compromising on features or performance, the BF’s design cuts out everything that distracts from your interaction with the image. From its aluminum unibody to its simplified controls and streamlined menu, the BF embodies a pure photographic experience free of frustration.

SEEMLESS INTERACTION

The Sigma BF represents a new, more intuitive way to use a camera. It is streamlined to make the act of photography as effortless as possible. We have replaced the shooting mode dial – itself a holdover from the days of film photography – with direct access to the five elements that decide the photograph. Shutter speed, aperture, ISO, EV compensation and color mode are all immediately available at the touch of a finger. The new Status Monitor displays the currently active setting, so the screen provides an unobstructed view of the subject.

CLEAR VIEW

The BF's high-resolution screen provides a distraction-free view of all necessary information – and nothing more. With one simple setting, it shows only the live view image, with the five key elements – shutter speed, aperture, ISO, EV compensation and color mode – displayed when you are ready to press The center button. All other options and settings are accessed via just three simple menu screens.

AT A GLANCE

The innovative Status Monitor displays the active setting, highlighting exactly what you need to know without distraction.

TACTILE CONTROL

With just three buttons and a dial pad, the BF’s redesigned user interface makes adjustments instant and intuitive, leaving your attention on the scene and not the settings. As the first mirrorless camera*, the BF features pressure-sensitive haptic buttons, resulting in minimal physical wear while still offering the precise and tactile sensation of conventional mechanical buttons.
