Still taping filters? Not anymore! -- Shipping Worldwide 🌍Designed in Amsterdam

24/02/2026

BSC Expo 2026, here’s the recap!

We launched the CGA-138, caught up with familiar faces, and introduced the Bun-G-Ring to plenty of people who hadn’t seen it before. The response to both products made the trip worth every minute.

Thanks to everyone who stopped by. A specific thanks to , and for demonstrating the system the way it was meant to be used.

The CGA-138 is now available via our webshop.

Closer focus: without a bulky matte box.

With the Circular Glass Adapter, working with diopters no longer relies on tape or improvised solutions when a traditional matte box is too large or in the way. By design, the CGA lets you work extremely close to the subject.

Multiple CGAs can be stacked when additional diopter magnification is needed. Rectangular filters can be positioned in front of or between the CGA and the Bun-G-Ring, depending on your magnification needs, while an integrated silicone Grip Seal protects the glass.

Now available to order via our webshop for a limited BSC Expo introductory price.
Expected to ship in week 12.

Spotted in Berlin 🎬
Focus puller Gemma Probst () needed to keep the setup tight for a high-speed car stunt. No loose components inside the vehicle. On this new project with cinematographer Robbie van Brussel ( , the matte box stayed off, but a clear filter still protected the lens, held firmly in place by the Bun-G-Ring.

🎥 When every millimeter counts.

On set with Dutch focus puller Luuk, where the Sony Venice in Rialto mode on a Cinebot Mini had to glide just above a table. A matte box? Too big. Casting unwanted shadows.
No problem for the Bun-G-Ring.
