GODOX AK-R21 Projection Attachment for Round Head Flashes with 65mm Lens, 8 Gobos, Color Filters, Magnetic Mount

The GODOX AK-R21 Projection Attachment transforms compatible Godox round head flashes into precision optical spotlights, enabling photographers to project crisp patterns, shapes, and colored light effects directly onto subjects or backgrounds. Unlike conventional modifiers that diffuse or soften light, this attachment focuses the flash output through a 65mm aspherical lens system, delivering a defined beam with adjustable focus for creative control in portrait, product, and fine-art photography.

Highlights

• Magnetic mounting system compatible with Godox AK-R1 accessory ecosystem
• 65mm optical projection lens with manual focus for sharp or soft edge transitions
• Includes 8 stainless steel gobo patterns for immediate creative projection
• Integrated color filter slot for adding dramatic color washes or accent lighting
• Robust aluminum alloy and ABS construction with optical glass elements
• Supports both flash and LED modeling lamp use for precise pre-visualization

In daily use

The AK-R21 attaches instantly to the magnetic front of Godox V1, AD100Pro, or AD200Pro flashes (with H200R round head adapter), turning a standard speedlight into a dedicated projection tool. The adjustable focus ring allows you to transition from a hard-edged spotlight for graphic backgrounds to a softer beam for subtle hair or accent lighting. The included gobo holder accepts the eight supplied patterns—ranging from window blinds and foliage to abstract shapes—letting you simulate natural light effects or add texture to seamless backdrops. For color work, the filter slot accepts standard gel filters, enabling you to project saturated hues or correct color temperature on the fly. With a light loss of approximately 1.5–2 stops, the AK-R21 is best used in controlled studio environments where you can compensate with higher flash power or wider apertures. The compact design fits in most lighting bags, and the included storage case keeps all accessories organized.
