NiSi Wide Conversion Lens Kit for Ricoh GR III

The NiSi Wide Conversion Lens Kit for Ricoh GR III is a complete wide-angle camera accessory kit designed to expand the creative shooting capabilities of the Ricoh GR III while preserving the camera’s compact, fast, and discreet shooting experience. Built for photographers who want a broader field of view without changing camera systems, this kit transforms the GR III’s native 28mm equivalent focal length into a wider 21mm equivalent perspective.

This complete kit includes the NiSi PR-10 0.78x Wide Conversion Lens and the dedicated NiSi PR-11 49mm Filter Adapter MKII for Ricoh GR III. Once installed, the system gives street photographers, travel shooters, landscape photographers, architecture photographers, and interior photographers a wider angle of view for capturing more context, depth, and environmental detail in every frame. It is especially useful in tight spaces, busy city scenes, indoor locations, and situations where stepping farther back is not possible.

The included 49mm Filter Adapter MKII is purpose-built for the Ricoh GR III body and replaces the Ricoh GN-1 ring adapter. It provides a secure, clean, integrated connection for the wide conversion lens while also supporting standard 49mm filters when the wide-angle lens is removed. This makes it possible to use ND filters, CPL filters, UV filters, protection filters, diffusion filters, Black Mist filters, and other creative filter effects with the Ricoh GR III.

Designed for dependable everyday use, the wide conversion lens features advanced multi-layer nano coating to help reduce flare, ghosting, and internal reflections while improving clarity, contrast, and color reproduction. The aluminum alloy construction keeps the kit durable and lightweight, while the secure auto-lock adapter helps prevent loosening or accidental detachment during handheld shooting, travel, and fast-paced street photography. The kit also retains normal camera functionality, including autofocus, metering, auto exposure, and shooting modes.
