Overview

The NiSi Wide Conversion Lens Kit for Ricoh GR IV is a complete wide-angle solution designed for photographers who want to expand the creative flexibility of the Ricoh GR IV while maintaining the camera’s compact form factor, fast operation, and portable everyday-carry design. By transforming the GR IV into a 21mm equivalent wide-angle camera, the kit enables users to capture broader scenes, more immersive perspectives, and increased environmental context without changing camera systems or sacrificing the discreet shooting experience that makes the GR series so popular. Designed specifically for the GR IV, the kit combines the NiSi PR-10 Wide Conversion Lens with a dedicated NiSi 49 mm Filter Adapter, creating a secure and seamlessly integrated setup suited to street photography, travel, architecture, landscapes, interiors, and documentary work.

Expanded Creative Perspective

The 21mm equivalent field of view allows photographers to capture wider street scenes, expansive landscapes, interiors, architecture, and immersive environmental compositions while preserving the intuitive handling and speed of the Ricoh GR IV.

Purpose-Built Adapter Design

The included NiSi 49 mm Filter Adapter replaces the Ricoh GN-3 ring and provides a secure threaded mounting point for the wide conversion lens. Precision machining delivers a stable, gap-free fit that integrates naturally with the camera body.

Creative Filter Flexibility

When the conversion lens is removed, the adapter retains a standard 49 mm filter thread for attaching ND, CPL, UV, Black Mist, and other specialty filters. This provides additional creative control for photography and video shooting applications.

Advanced Optical Performance

NiSi’s multi-layer nano coating technology helps suppress flare, ghosting, and internal reflections in difficult lighting conditions such as direct sunlight, reflective environments, and nighttime city scenes. The result is improved contrast, sharpness, and colour accuracy.

Built for Everyday Carry

The conversion lens and adapter are both constructed from lightweight aluminum alloy for durability during daily use and travel. Included front and rear metal caps help protect the lens during transport and storage while complementing the premium finish of the GR IV system.
