Frequently Asked Questions (FAQ)

Which flashes are compatible with the Godox AK-R21? The AK-R21 is designed for versatility. Out of the box, it includes the adapter for round-head flashes like the Godox V1, V1P, V1N, V1S and AD100Pro. With the optional AK-R25 adapter, it can also be used with traditional rectangular Fresnel flashes like the V860III, V850III, and TT685II.

Can I adjust the sharpness of the projected image? Yes. By sliding the lens barrel forward or backward, you can precisely control the focus of the projection, ranging from razor-sharp lines to a soft, diffused glow.

Do I need special slides for this attachment? The AK-R21 uses Godox-specific slides. While it comes with two demo slides, Godox offers several sets (sold separately) featuring various creative patterns and scenic backgrounds.

Does it get hot during use? The AK-R21 is built with heat-resistant materials; however, when using a powerful modeling light on flashes like the AD200Pro, it is recommended to monitor the heat levels during extended sessions.
