Product Description
Simplicity Meets Power
The Sigma BF Mirrorless Camera is a 24.6MP full-frame imaging tool designed to redefine the digital camera experience. With an intuitive interface, hybrid autofocus, and 6K video capabilities, it blends effortless usability with professional-grade performance—allowing photographers and filmmakers to focus on creativity, not complexity.
Redesigned for Intuitive Control
Refined User Interface
The Sigma BF streamlines image-making by simplifying the user experience. Key settings like shutter speed, aperture, ISO, EV compensation, and color modes are seamlessly integrated into the live-view touchscreen, ensuring effortless adjustments while keeping the subject in focus.
Minimalist Physical Design
Breaking from traditional camera layouts, the Sigma BF features just three essential controls: a dial, a shutter release, and a power button, complemented by a pressure-sensitive rear dial pad for navigation. The camera's unibody aluminum construction, carved from a single block, provides a balanced, lightweight feel while enhancing durability.
Professional-Grade Imaging
High-Resolution Sensor & Dynamic Range
At its core, the 24.6MP full-frame, backside-illuminated CMOS sensor delivers exceptional clarity, wide dynamic range, and superior low-light performance.
✔ Native ISO 100-102400, expandable down to ISO 6 for long-exposure and fine-art photography
✔ Hybrid phase and contrast detection autofocus ensures fast, accurate focusing
6K Video & Advanced Recording Features
Catering to videographers, the Sigma BF offers:
✔ 6K recording at 30 fps, with Full HD up to 120 fps for slow-motion capture
✔ L-Log color grading for post-production flexibility
✔ HEVC encoding for efficient, high-quality compression
Expanded Storage & Connectivity
✔ 230GB internal storage—enough for 14,000+ JPEGs, 4,300 RAW files, or 2.5 hours of video
✔ USB-C port for high-speed data transfer and external storage support
