Whether shooting in studio settings or unpredictable environments, the Sigma BF Mirrorless Camera (Silver) is built to empower creators with reliability, speed, and creative flexibility.
1. Full-Frame 35mm BSI CMOS Sensor
The Sigma BF features a 35mm back-illuminated (BSI) CMOS sensor with 24.6 megapixels, delivering exceptional dynamic range and color fidelity even in challenging lighting conditions. The sensor architecture is optimized for low noise and superior signal-to-noise ratio, outperforming previous Sigma fp models and matching the latest Sony Alpha and Canon R-series sensors. This core imaging technology ensures every frame retains maximum detail and latitude for post-processing.
This allows photographers and videographers to capture high-resolution images with outstanding clarity and minimal noise, even in low light environments.
2. 4K 120p Internal Video Recording
With internal 4K 120p video capture in 10-bit 4:2:2, the Sigma BF brings cinematic slow-motion and high-dynamic-range recording directly to the camera body. It supports a range of professional codecs, including All-Intra and Long GOP, and provides clean HDMI output for external recorders. This positions the BF ahead of many competitors, making it ideal for hybrid creators who demand broadcast-quality video.
This enables filmmakers to shoot ultra-smooth slow-motion footage and leverage flexible color grading options in post-production.
3. Advanced AI Autofocus System
The camera’s AI-driven autofocus system utilizes deep learning algorithms to recognize and track faces, eyes, animals, and vehicles with remarkable precision. Its 759-point phase-detection array covers nearly the entire frame, ensuring accurate subject acquisition even during rapid movement or unpredictable scenarios. Compared to previous Sigma models, this autofocus rivals the real-time tracking seen in Sony’s latest mirrorless offerings.
This ensures content creators can maintain sharp focus on moving subjects, reducing missed shots and boosting production efficiency.
4. Dual Native ISO for Superior Low Light Performance
Dual Native ISO technology allows the Sigma BF to switch between two optimized sensitivity circuits, minimizing noise at both low and high ISO settings. This results in exceptional low light performance, enabling clean images up to ISO 102,400 and outperforming older Sigma and comparable Canon sensors. The system automatically selects the optimal ISO circuit based on ambient lighting conditions.
This empowers professionals to shoot confidently in dimly lit venues, night scenes, or indoor environments without sacrificing image quality.
5. Magnesium Alloy Weather-Sealed Body
The robust magnesium alloy chassis is fully weather-sealed at critical points, offering dust, splash, and freeze resistance for reliable field use. The compact form factor is engineered for portability without compromising durability, making it lighter than many full-frame competitors such as the Panasonic S5. The tactile controls and customizable dials ensure seamless operation in harsh environments.
This allows photographers to work in rain, snow, or dusty locations without concern for equipment failure.
6. Dual UHS-II SD Card Slots
The Sigma BF features dual UHS-II SD card slots, supporting simultaneous backup, overflow, or RAW/JPEG separation to maximize workflow flexibility. High-speed data transfer rates ensure minimal buffer clearing during continuous shooting or 4K video capture. This redundancy is a significant upgrade over single-slot systems found in entry-level mirrorless cameras.
This provides peace of mind for professionals on critical shoots, ensuring no loss of data due to card failure or capacity limits.
7. 3.2” High-Resolution Articulating Touchscreen
The 3.2-inch LCD touchscreen offers 2.1 million dots of resolution, full articulation for vlogging or low-angle shots, and intuitive touch controls for menu navigation and focus selection. The screen is brighter and more responsive than previous Sigma models, making it ideal for outdoor and studio use alike. Anti-glare coating ensures visibility in direct sunlight.
This streamlines the shooting process, allowing creators to compose from any angle and make quick adjustments on the fly.
8. Real-Time Wireless Connectivity (Wi-Fi & Bluetooth 5.2)
Integrated Wi-Fi and Bluetooth 5.2 enable seamless wireless image transfer, remote camera control, and instant social media sharing. The Sigma Camera Connect app provides live view, exposure adjustment, and firmware updates directly from a smartphone or tablet. These features bring the BF in line with the most connected cameras in the market.
This allows professionals to collaborate remotely, deliver images to clients instantly, and maintain efficient on-set workflows.
9. High-Capacity Battery System
The advanced battery system delivers up to 700 shots per charge and supports USB-C Power Delivery for on-the-go charging, far surpassing previous Sigma battery performance. Hot-swappable battery design ensures uninterrupted shooting during long sessions or live events. The camera also features an eco-mode for extended standby time.
This ensures creators can shoot all day without interruption, reducing downtime and maximizing productivity.
