NiSi Wide Conversion Lens Kit for Ricoh GR III

The NiSi Wide Conversion Lens Kit for Ricoh GR III is a complete wide-angle accessory kit designed to help photographers capture more of the scene without compromising the camera’s compact, fast, and discreet shooting experience. Ideal for street, travel, landscape, architecture, and interior photography, the kit components are made of lightweight, durable, and precision-machined aluminum alloy. It includes the NiSi's PR-10 wide conversion lens that boasts 0.78x magnification and the dedicated NiSi PR-11 49mm filter adapter MKII for Ricoh GR III. These provide everything needed to mount the conversion lens securely to the camera. Once attached, the system transforms the GR III's native 28mm equivalent focal length into a wider 21mm equivalent field of view.

Wider Perspective

The NiSi PR-10 0.78x wide conversion lens expands the Ricoh GR III's native 28mm equivalent lens to an ultrawide 21mm equivalent field of view. This wider field of view captures more of the surrounding environment. It is especially useful in tight spaces, busy urban locations, or situations where stepping back is not possible. The conversion lens features a durable aluminum alloy frame and comes with front and rear metal caps for protection when not in use.

Dedicated Adapter

The included NiSi 49mm filter adapter MKII for Ricoh GR III is purpose-built for the GR III body and replaces the Ricoh GN-1 ring adapter. It provides a secure threaded connection for the wide conversion lens while maintaining a clean, integrated profile on the camera. It features NiSi's secure auto-lock mechanism, which is designed to prevent loosening or accidental detachment during use. The adapter is precision-machined from aluminum alloy, providing a lightweight yet reliable connection between the camera and lens.

Macro Mode Compatible

The NiSi wide conversion lens is fully compatible with the Ricoh GR III macro mode. It enables moving from wide-angle scenes to close-up details without removing the lens. This makes the kit suitable for photographers who work quickly and want to keep their camera ready for a wide range of subjects.

Antireflective Nano Coating

The optical elements feature NiSi's advanced multilayer nano coating to help reduce internal reflections, flare, and ghosting. The coating helps maintain cleaner contrast, better clarity, and richer color reproduction across the frame. This is especially useful when shooting in bright sunlight, strong backlight, city lights, or high-contrast environments.

Filter Compatibility

With the wide-angle conversion lens removed, the included adapter provides a standard 49mm filter thread for expanding the camera's creative and protective options. This facilitates two practical shooting setups: use the wide conversion lens for a 21mm equivalent field of view, or remove it and use the standard 49mm filters for light control, protection, or creative filter effects.

Full Functionality Retained

The kit does not interfere with normal camera operations. Autofocus, metering, auto exposure, and shooting modes continue to work as expected, allowing the camera to remain fast, responsive, and ready to shoot. It simply expands the camera's perspective while adding secure adapter integration, macro mode support, and premium optical performance in a compact, purpose-built system.

Durable Build

The lens and the adapter are made from durable, lightweight aluminum alloy. The included front and rear metal lens caps protect the optics from dust, scratches, and damage when the lens is stored or transported.
