1. Compatibility: Designed for Bowens style speedrings, with the option to swap to other speedrings. Interchangeable mounting adapters support different bayonets. Mount diameter is 95 mm. 2. Multifunction: The focus ring delivers a clearer projection. You can adjust the projection from narrow to wide angle and manually change the iris size. This makes it well suited for portraits and product photography. 3. Creative options: Gobos and color gels can be used together or separately to create special lighting effects, providing more possibilities for creative shoots. Use scenarios: - Portrait photography: shape and control light to enhance features and create desired falloff. - Product photography: precisely project and sculpt light to emphasize texture and detail. - Creative/Set lighting: deploy gobos and gels to produce mood, patterns, or color effects for scenes.
