Sigma BF Review: A Bold Step Towards Simplicity in Photography

In the world of modern cameras, the Sigma BF stands out as a daring and unconventional creation. With its aggressively minimalistic design, sharp edges, and a near-buttonless interface, this camera challenges traditional photography norms. However, does its simplicity enhance or hinder the user experience? Let’s dive into the details to determine whether the Sigma BF is a game-changer or just a niche experiment.

A Design Unlike Any Other

The first thing that catches your eye about the Sigma BF is its radical design. It strips away many standard camera features—no viewfinder, no flip or tilt screen, no external storage, and not even a traditional hot shoe mount. The body itself is sharp-edged, which at first glance might seem uncomfortable to hold. However, despite these drastic choices, the design surprisingly works well for its intended purpose.

This camera isn’t built for professional studio work or high-intensity shooting environments. Instead, it positions itself as an “everyday camera,” perfect for street photographers and enthusiasts who want a premium yet simple shooting experience. Think of it as an alternative to the Leica Q, Nikon ZF, or Fujifilm X100 series—a camera meant to be paired with your favorite lens and carried everywhere.

Handling and Ergonomics: Not Perfect, But Functional

While the design is striking, it does come with a few ergonomic drawbacks. The lack of a second strap link makes single-handed operation challenging. However, despite its boxy shape, it doesn’t feel outright uncomfortable during use.

A bigger concern is battery life. The Sigma BF requires frequent charging, sometimes up to twice a day with heavy use. The battery indicator, displayed in percentages, adds to the anxiety by making battery drain more noticeable. Additionally, the absence of in-body stabilization means that users must rely on lenses with optical stabilization, which may limit their shooting options.

Innovative Controls and User Experience

Sigma has taken an unconventional approach to controls by relying heavily on a single multifunctional dial. This dial replaces multiple traditional buttons and, when paired with the small sub-monitor above it, makes adjusting settings intuitive.

Pressing left or right cycles through settings, while rotating the dial adjusts parameters such as white balance, shutter speed, and ISO. Users can experiment freely with aspect ratios, film simulations, and exposure settings without digging through complex menus. One particularly clever feature is the dial’s secondary function—it automatically switches to exposure compensation when the shutter button is half-pressed, allowing for quick adjustments on the fly.

Additionally, the interface is one of the cleanest in the industry. The menu system is streamlined, easy to navigate, and free from unnecessary clutter. While customization options are limited, the simplicity makes the Sigma BF an enjoyable camera to use.

Internal Storage: A Double-Edged Sword

One of the most controversial aspects of the Sigma BF is its storage solution. Instead of using SD cards, the camera features 230GB of built-in SSD storage. While this contributes to the camera’s fast performance and eliminates concerns about forgetting an SD card, it also introduces some serious drawbacks.

First, if the internal storage fails, there’s no easy way to replace it. Unlike swapping out a corrupted SD card, a failure in the built-in SSD could render the camera unusable. Second, transferring photos is more cumbersome than it should be. With no dedicated mobile app and no wireless transfer options, users must rely on a physical cable to move files—a surprisingly outdated approach for a camera designed with modern simplicity in mind.

Image Quality: Stunning Yet Simple

At the heart of the Sigma BF is a 24.6MP full-frame back-illuminated sensor. Paired with the 50mm f/2 lens, the camera produces stunningly sharp and detailed images. High ISO performance is excellent, with minimal noise and vibrant color reproduction. Autofocus is reliable for photography, though it struggles with video, often exhibiting focus breathing and drifting issues.

The built-in film simulations add another layer of creative control. With 13 different looks to choose from, users can experiment with various styles straight out of the camera. The “Warm Gold” simulation, for instance, delivers warm tones and muted reds, while “Rich” enhances contrast and deepens blues. Unfortunately, there’s no way to create custom film simulations, limiting users to Sigma’s pre-defined styles.

Video Capabilities: An Afterthought?

While the Sigma BF technically supports 6K recording at 30fps and 1080p slow motion up to 120fps, video feels like an afterthought. There’s no 4K 60fps option, which is a notable omission in a $2,000 camera. Additionally, the electronic-only shutter lacks the satisfying mechanical feel of traditional shutters and can introduce issues under fluorescent lighting.

For those primarily interested in video recording, the Sigma BF is not the ideal choice. It’s clear that the focus of this camera is still photography, with video included merely as a secondary feature.

Final Verdict: A Camera That Wins You Over

The Sigma BF is not for everyone. It lacks many features that photographers have come to expect, and its high price tag makes it a tough sell for casual users. However, for those who appreciate its simplicity, innovative design, and high-quality image output, it has the potential to be a beloved everyday camera.

This camera is a bold experiment that embraces minimalism in a way few others do. While it may not be a commercial hit, it is certainly a statement piece—one that will leave a lasting impression on those who give it a chance. If you can look past its limitations, the Sigma BF might just redefine the way you experience photography.
