Product Features in Detail

NiSi Wide Conversion Lens Kit for Ricoh GR IV
The NiSi Wide Conversion Lens Kit for Ricoh GR IV is a complete wide-angle accessory kit designed to help GR IV photographers capture more of the scene without compromising the camera’s compact, responsive shooting style.

This kit includes the NiSi PR-10 0.78x Wide Conversion Lens and the dedicated NiSi 49mm Filter Adapter for Ricoh GR IV. Together, they provide a secure and practical way to transform the GR IV’s native 28mm equivalent lens into a wider 21mm equivalent field of view.

Designed for street photographers, travel shooters, landscape photographers, architectural photographers, and creative everyday users, this kit expands the GR IV into a more versatile wide-angle system.

21mm Equivalent Wide-Angle Perspective
Mounted on the Ricoh GR IV, the NiSi PR-10 Wide Conversion Lens widens the camera’s native 28mm equivalent focal length to 21mm equivalent. This wider perspective allows you to capture more of the environment, making it easier to photograph large scenes, tight interiors, dramatic architecture, expansive landscapes, and immersive street compositions.

The wider field of view is especially useful when you want to create a stronger sense of space and depth while still working with the compact GR shooting style.

Complete Kit with Dedicated GR IV Adapter
The included NiSi 49mm Filter Adapter for Ricoh GR IV is designed specifically for the GR IV and replaces the Ricoh GN-3 ring. It gives the camera a secure 49mm threaded connection for mounting the wide conversion lens.

The adapter integrates cleanly with the GR IV body, maintaining the camera’s sleek and compact look while adding significant creative functionality.

Secure Auto-Lock Mechanism
The adapter features NiSi’s precision auto-lock mechanism, which helps prevent loosening or accidental detachment during use. Once installed, the adapter stays firmly in place, providing a stable and confidence-inspiring connection for the wide conversion lens.

This is especially important for handheld photography, travel, fast-paced street work, and everyday shooting where reliability matters.

Macro Mode Compatible
The NiSi Wide Conversion Lens is compatible with the Ricoh GR IV Macro Mode, allowing you to shoot close-up subjects without removing the lens. This gives you the freedom to move quickly between wide environmental frames and detailed close-up images.

For photographers who want to keep their setup ready and responsive, this makes the kit highly practical in real-world use.

Advanced Anti-Reflective Nano Coating
The PR-10 Wide Conversion Lens uses NiSi’s advanced multi-layer nano coating to help reduce internal reflections, flare, and ghosting. This improves contrast and clarity when shooting in difficult lighting conditions, such as strong backlight, direct sun, reflective surfaces, or bright night scenes.

The result is cleaner image quality, improved colour saturation, and better overall optical performance.

49mm 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. You can mount ND filters for long exposures or video, CPL filters for reflection control and improved colour saturation, UV or clear protection filters for daily lens protection, and creative filters such as Black Mist or diffusion filters.

This gives the Ricoh GR IV two practical shooting setups: use the wide conversion lens when you want a 21mm equivalent field of view, or remove it and use standard 49mm filters when you want light control, protection, or creative filter effects.

Premium Build Quality
The NiSi Wide Conversion Lens is built with a precision-machined aluminum alloy frame, offering a balance of durability, low weight, and premium handling. The included front and rear metal lens caps protect the optics from dust, scratches, and damage when the lens is stored or transported.

The adapter is also constructed from durable aluminum alloy, providing long-term reliability while maintaining the compact feel of the Ricoh GR IV.

Full Camera Functionality Retained
The NiSi Wide Conversion Lens Kit is designed to integrate seamlessly with the Ricoh GR IV. Autofocus, metering, auto exposure, and shooting modes continue to operate normally, so the camera remains quick, intuitive, and ready to shoot.

There is no complicated setup required. Attach the adapter, mount the lens, and start shooting with a wider perspective.

Expand What the GR IV Can Capture
The NiSi Wide Conversion Lens Kit for Ricoh GR IV is an ideal accessory for photographers who want to go wider while keeping the compact handling and image quality of the GR IV. By expanding the camera to a 21mm equivalent field of view, it opens new creative possibilities for street photography, landscapes, architecture, travel, interiors, and everyday visual storytelling.

For GR IV shooters who want a wider perspective in a secure, premium, and purpose-built system, this kit is a powerful addition to the camera.
