Helium BF: an all-aluminium grip designed for the Sigma BF

Helium Design Lab unveils an aluminum grip for the Sigma BF, an accessory that promises to improve the camera’s grip while preserving its minimalist design. The grip features Arca-Swiss compatibility and a dedicated AirTag slot.

An aluminum grip to maintain the aesthetic appeal of the Sigma BF

After grips for the Leica Q3 and Leica M11, Helium Design Lab recently presented a new grip specially designed for the Sigma BF camera, created in collaboration with photographer Hugh Brownstone and designer Ed Palisoc.

The Sigma BF, known for its one-piece aluminum design, appeals to purists with its minimalist approach. However, the absence of a grip can make the experience less comfortable over long sessions. The Helium BF seeks to correct this shortcoming by improving the device’s balance and stability, according to its designers.

Made from “high-quality aeronautical aluminum”, the Helium BF (or He BF) grip is designed to provide a comfortable, secure hold. A look at the 3D rendering video reveals that the grip, instead of being solid, is hollow, so that fingers can be placed inside.

Arca-Swiss and Apple AirTag compatibility

Its compatibility with the Arca-Swiss system and Peak Design Capture Clip makes it versatile and suitable for a variety of uses.

One of the grip’s major assets is its dedicated slot for an AirTag, enabling users to easily locate their device in the event of loss. What’s more, its design allows quick access to the battery, a handy detail for long photo sessions. Nor does it obstruct the USB-C port.

Too bad, the grip doesn‘t seem to add a second clip for attaching a camera strap to either side of the camera, which is currently impossible.

Price and availability

Having just launched the Sigma BF, Helium Design Lab remains cautious about the development of this accessory. Given the niche represented by the Sigma BF, the brand wishes to gauge interest before launching production.

No price or availability has yet been announced. A pre-order form should be shared by Helium Design Lan to assess demand.

Our first impressions on the Helium BF grip

With its minimalist appearance, the Sigma BF – like the Sigma fp and fp L cameras – requires a grip for a more comfortable hold. Its design seems to harmonize perfectly with the Sigma BF, at least in theory. Features such as the Apple AirTag slot and Arca Swiss compatibility are very useful. It now remains to be seen whether demand will be sufficient to bring this project to fruition. To be continued.
