Sigma has launched the Sigma BF, a 24.6MP full-frame mirrorless camera that focuses on simplicity, ease of use, and modern design. Unlike traditional cameras, the Sigma BF features a minimalist unibody design, intuitive controls, and built-in storage, making it a unique addition to the camera market.
Instead of a memory card slot, the Sigma BF includes 230GB of built-in storage. This lets users save up to 14,000 JPEG photos, 4,300 RAW images, or 2.5 hours of high-quality video.
Built-in Storage Instead of Memory Cards
With a sleek, lightweight unibody aluminum design, the camera measures 5.1 x 2.9 x 1.4 inches and weighs 388 grams. Instead of multiple buttons and dials, it features a minimalist layout with just four buttons, a dial, and a touchscreen.
Unlike traditional cameras, the Sigma BF does not have a memory card slot. Instead, it comes with 230GB of built-in SSD storage, allowing users to store 14,000+ JPEG images, 4,300 RAW images, and 2.5 hours of 6K video. Moreover, the files can be transferred via USB-C, which also serves as the charging port or interface.
Camera Performance and Features
The Sigma BF is a user-friendly camera built for photographers and designed for a hassle-free experience. It has a 24.6MP full-frame sensor that captures high-quality images and an ISO range of 100 to 102,400 (expandable to ISO 6) for great low-light shots or say photography.
For video recording, the camera supports 6K video at 30 fps and Full HD at 120 fps. Its hybrid autofocus system ensures fast and accurate, quick focusing on people, dogs, and cats. The lightweight aluminum body is durable and has simple controls: just four buttons, a dial, and a touchscreen.
With 13 built-in color modes like Forest Green, Warm Gold, Teal, and Monochrome, allowing users to add or create unique creative styles without editing. The BF has a USB-C port for charging and file transfers (it doesn’t use memory cards) and works with Sigma, Panasonic, and Leica lenses through the L-Mount system.
Limitations
While the Sigma BF offers a modern and easy-to-use design, it lacks an electronic viewfinder (EVF), a fully adjustable screen, and microphone and headphone jacks, making it less ideal for professional videographers. The battery lasts about one hour for video recording, and users must rely entirely on the internal SSD for storage.
Who Is It For?
The Sigma BF is aimed at photographers who prefer a simple, stylish camera without complicated settings. It may also appeal to smartphone users looking to upgrade to a full-frame camera without a steep learning curve.
Pricing and Availability
The Sigma BF will be available in black and silver for $1,999, with shipments starting in April 2025. However, the price does not include a lens, and users will need to buy L-Mount compatible lenses separately.
Alongside the BF launch, Sigma is also updating its I Series compact prime lenses, introducing a silver finish to match the silver BF model and adding magnetic lens caps to the 45mm f/2.8 DG lens. These updates will be available in April for L-mount and May for Sony E-mount.
With its simple design, built-in storage, and high-quality sensor, the Sigma BF offers a fresh approach to camera design. While it may not replace professional video cameras, it challenges traditional camera features and provides a modern option for photographers who value ease of use.
