Ricoh Lens Holder

Street photographers using the Ricoh GR III or GR IIIx often want to expand their creative options with wide-angle or tele conversion lenses, or simply protect the front element with a filter. This Ricoh Lens Holder provides a secure, precision-machined bayonet mount that snaps onto the camera's lens barrel, then offers a standard 49mm screw thread on the front. That means you can attach the Ricoh GW-4 Wide Conversion Lens, the GT-2 Tele Conversion Lens, or any 49mm filter or accessory. Made from lightweight yet durable aluminum alloy with a black finish, it matches the camera's minimalist design and adds minimal bulk. The adapter includes front and rear lens caps to keep everything clean when not in use. No optical elements are involved, so image quality remains unchanged. It's the essential bridge between your GR camera and a world of lens accessories.

Why choose it

The Ricoh Lens Holder is the only adapter that guarantees perfect alignment and secure attachment for conversion lenses on your GR III or GR IIIx. Unlike generic third-party adapters, it's engineered to the exact flange distance and bayonet geometry of the camera, ensuring sharp, corner-to-corner performance with the GW-4 and GT-2. The 49mm thread opens up a huge ecosystem of filters—UV, polarizers, ND—for creative control. Its lightweight design won't upset the camera's pocketable balance, and the included caps protect both the adapter's threads and your camera's front element when stored.

Ideal use cases

• Attaching the Ricoh GW-4 wide conversion lens for 21mm equivalent ultra-wide shots.
• Mounting the Ricoh GT-2 tele conversion lens for 75mm equivalent portraits or details.
• Adding 49mm filters such as circular polarizers or neutral density filters for landscape and long-exposure work.
• Protecting the camera's built-in lens with a UV filter when shooting in dusty or sandy environments.
• Using the adapter as a lens hood base for custom hoods or step-up rings.

Good to know

The adapter installs by aligning the bayonet lugs and rotating until it clicks into place—no tools required. It is not weather-sealed, so avoid use in heavy rain or blowing sand. The adapter adds approximately 10mm to the camera's depth, which may affect fit in some tight cases. Always remove the adapter before retracting the camera's lens (when powered off). The 49mm thread is compatible with most standard filters and accessories from major brands. For best results with conversion lenses, ensure the adapter is fully seated and the accessory is screwed on snugly but not overtightened.
