The Elinchrom OCF Barndoor features four trapezoidal metal wings that can be attached directly to the device to shape the light distribution in all directions or to focus the light into a rectangular beam. The wing system is ideal for targeted light control, allowing for the achievement of any effect without hassle. The Elinchrom wing frame is specifically designed for the OCF system and is compatible with the Elinchrom ONE and FIVE devices, as well as with the Profoto system.
