Overview

The Profoto 101040 OCF II Gel Ring is a purpose-built accessory for photographers who want to introduce color effects into their lighting setups quickly and without fuss. Designed to work with Profoto's flat front flash heads — including the B10, B10 Plus, and B1X — this gel ring uses a magnetic attachment system that snaps securely onto the OCF II Grid and Gel Holder or the OCF II Barndoor. This means you can swap gels in seconds between shots, keeping your creative momentum going whether you're in the studio or on location.

Where the OCF II Gel Ring really earns its place in a kit bag is in its stackability. By layering it with OCF II Grids, you can combine precise beam control with color effects in a single, compact modifier stack. The ring is built to handle the demands of professional use while remaining lightweight enough for travel. It's a focused, single-purpose accessory that does one job well: holding your gels securely and letting you change them fast. Just keep in mind that gels and a compatible holder or barndoor are purchased separately.
