Profoto OCF Speedring, code 101210, is an adapter ring designed to mount Profoto OCF softboxes and beauty dishes on compatible Profoto off-camera flashes. It is the required component for connecting modifiers such as OCF Softboxes, OCF Beauty Dish, and dedicated accessories to Profoto flash heads with LED modeling lights, while maintaining a lightweight and quick-to-assemble system for location productions, portraiture, fashion, events, and commercial photography. The compact structure uses materials such as aluminum and silicone, with a quick mounting system designed to simplify softbox rod installation and reduce setup time on set. The color-coded holes help insert the rods correctly, while the rubber collar allows 360° rotation of the modifier on the flash head, useful for positioning rectangular or strip softboxes vertically, horizontally, or diagonally. The weight is approximately 240 g according to Profoto specifications, with a format designed for transport together with the OCF system. Profoto OCF Speedring is suitable for photographers using Profoto flashes such as B1, B1X, B2, B10, and compatible models who need a dedicated adapter for OCF modifiers. It is not a universal adapter for all Profoto modifiers and should be used with compatible OCF accessories, avoiding flash heads or modeling lamps that generate high heat.
