Helium Design Lab unveils anti-theft grip for Leica SL3 series

Leica SL3 owners who have been waiting for a smarter native-style grip got an answer from an accessory maker built around the same complaint: premium cameras still leave room for better handling, better balance and better security. Helium Design Lab’s HeSL3 is aimed at the Leica SL3 series, including the SL3-S, and it went up for preorder at $320 with shipping expected in the second week of June.

The pitch is not just about adding a place to hold the camera. Helium framed the HeSL3 as an anti-theft, anti-futz interface plate that preserves the SL3’s original form while addressing the kind of workflow friction that matters once heavier lenses go on the body. The grip is made from fully CNC’d 6061-T6 aluminum, is hand-assembled and individually inspected, and still leaves battery and SD-card access open without removing the grip. It also accommodates an Apple AirTag securely and invisibly, a small but practical answer for photographers who move expensive bodies through airports, rentals or crowded locations.

Helium added more detail that makes the accessory feel built for working shooters rather than display shelves. The HeSL3 is compatible with Peak Design Capture Clip and Travel Tripod without an adapter plate, and it uses an anti-tamper approach for the AirTag and securing screw. A retaining clip is there to keep the mounting screw from getting lost, and a centerline mark helps align the optical axis. Those are the kinds of details that matter when a grip has to improve balance and ergonomics without turning the camera into a cumbersome rig.

The company behind it is small and specialized. Helium Design Lab identifies Hugh Brownstone and Ed Palisoc as the team behind the brand, with Brownstone known to many photographers through Three Blind Men and an Elephant and his workshops, and Palisoc bringing an architect’s eye to the product design. That background fits the company’s earlier work on Leica Q3, Q2 and M11 grips, as well as its Sigma BF accessory. Helium’s Q3 grip page says its design covers the Q3 28, Q3 43 and Q3 Monochrom, while the Q2 grip is not fully compatible with the Q3 because the bottom compartment layout is different.

The timing also fits Leica’s own system history. Leica announced the SL3-S on January 16, 2025, and the SL-System dates back to 2015 on the L-Mount standard. For a platform this expensive, the aftermarket keeps proving that comfort, security and balance are not luxury extras. They are the missing pieces that make the camera easier to live with, and the HeSL3 is built to solve exactly that.
