Universal Ring Flash Adapter RF 165 for Speedlight Flashes – 165 mm Diffuser for Macro & Portrait Photography

The RF 165 ring flash adapter transforms an ordinary hot-shoe speedlight into a professional ring light, delivering soft, shadowless illumination with the signature circular catchlight that defines high-end macro and fashion imagery. Unlike bulky dedicated ring flashes, this lightweight adapter mounts directly onto your existing flash head in seconds, preserving full TTL and manual control while adding a new creative dimension to your lighting kit.

Highlights

• Universal fit: adjustable strap/clamp accommodates flash heads from approximately 60 to 85 mm wide, covering most Canon, Nikon, Sony, Godox, Yongnuo, and other standard speedlights.
• 165 mm outer diameter produces a generous ring of light, ideal for close-up work, portraiture, and beauty photography.
• High-quality ABS plastic body with white diffuser panel ensures even light distribution and attractive circular catchlights in the subject's eyes.
• Reflective internal surfaces maximize light efficiency, with light loss limited to approximately 1.5–2 f-stops.
• Compact and rigid non-collapsible construction offers durability without adding significant weight to your camera setup.

In daily use

Attach the RF 165 to your flash, point it at your subject, and instantly achieve the flattering, wrap-around light that is difficult to replicate with traditional modifiers. For macro photography, the ring light eliminates harsh shadows and reveals fine details with even illumination. Portrait and fashion photographers will appreciate the distinctive circular catchlights that add a professional polish to every shot. The adapter works with both TTL and manual flash modes, and because it mounts directly to the flash head, you retain full mobility without extra stands or cables.
