BF Mirrorless Camera

    Do you remember the last time you shot with a camera that felt completely different? The Sigma BF is the first of its kind — a single aluminum unibody that’s a marriage of rugged build and sleek design. Tailored for minimalists, the BF features a super simple, foolproof interface with haptic buttons that give you quick access to key settings — shutter speed, aperture, ISO, exposure compensation, and color mode — all designed to keep things as straightforward as possible.

    Its high-resolution 23MP sensor delivers gorgeous photos for enthusiasts yet remains effortlessly approachable for beginners. The compact design means fewer moving parts for those always on the go, and thanks to its internal storage, it even eliminates the need for memory cards. This Sigma BF is a completely fresh shooting experience that everyone's talking about.

    SKU: C47900

    At a Glance: Key Features

    • An image without an alt, whoops

      Simplicity

      The Sigma BF skips the usual dials. Instead, you get a rear thumb wheel and d-pad. Controls run through a dual-screen setup: a mini LCD for settings and a big 3.2” screen for your image and menus. Instead of buttons, it uses touch-sensitive haptics for a slick, multi-function interface.

      Color Modes

      The Sigma BF comes with 13 built-in color modes for JPEGs and previews. If you want your own look, just pick a mode and tweak the settings to create your own custom vibe.

    • An image without an alt, whoops

      Versatile Lens System

      The Sigma BF has an interchangeable L-Mount, so you can use lenses from Lumix, Leica, DJI, Samyang, Sigma, and more. Basically, any current or future L-Mount glass will work perfectly.

      Unique Design

      The Sigma BF stands out with its sleek aluminum unibody and sharp-edged design; it’s as much a statement piece as it is a camera. It has just one strap mount, but you can easily add a shoulder strap using an anchor on the base.

    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.

    High Resolution Video

    Some stories are best told in moving images. With 6k recording, powerful HEVC encoding, L-Log support and up to 120 frames per second, the Sigma BF provides filmmakers with a nimble, versatile camera to capture and refine their vision.

    Full Frame Sensor

    The BF's 35mm full-frame sensor means stunning details, exceptional image quality, wide dynamic range and brilliant low-light performance. The large sensor size also translates to a shallower depth of field to separate subject and background, and allows the use of high-quality full-frame lenses.

    Internal Storage

    The SD card slot is replaced by 230GB of internal memory, capable of storing more than 14 000 JPEG files, 4 300 Lossless compression RAW images or 2.5 hours of video at the highest-quality setting, with the USB-C port offering fast charging and data-transfer speeds.

    Color Modes

    Comes with 13 stunning color modes – here are a few favorites.
