NiSi Wide Conversion Lens Kit for Ricoh GR IIIx

Description

Overview

The NiSi Wide Conversion Lens Kit for Ricoh GR IIIx is designed for photographers who want to widen the perspective of the GR IIIx while keeping the camera compact, fast, and intuitive to use.

This kit combines the NiSi PR-10 0.78x Wide Conversion Lens with the dedicated NiSi PR-12 49mm Filter Adapter MKII for Ricoh GR IIIx, giving you a complete mounting solution for expanding the GR IIIx’s native 40mm equivalent lens to approximately 31mm equivalent.

The result is a natural wide-angle field of view that feels highly versatile for street photography, documentary work, travel, lifestyle, and everyday shooting.

A Wider, More Flexible GR IIIx

The Ricoh GR IIIx is known for its 40mm equivalent perspective, offering a tighter and more natural field of view than the GR III. With the NiSi PR-10 Wide Conversion Lens mounted, the camera shifts to approximately 31mm equivalent, giving you more breathing room in the frame while still retaining a natural look.

This makes the kit especially useful for GR IIIx photographers who want extra context without switching to a different camera. It is ideal for street scenes, environmental portraits, city walks, travel, interiors, and documentary-style photography where a little more width can make the image stronger.

Complete Kit with Dedicated GR IIIx Adapter

The included NiSi 49mm Filter Adapter MKII for Ricoh GR IIIx is purpose-built for the GR IIIx body and replaces the Ricoh GN-2 ring adapter. It provides the secure 49mm threaded connection required to mount the wide conversion lens while maintaining a clean and integrated fit.

The adapter is precision-machined for a flush, gap-free, and play-free connection, so it feels like a natural part of the camera rather than an add-on accessory.

Secure Auto-Lock Mechanism

The adapter features a mechanical auto-lock system that keeps it firmly seated on the camera body. This helps prevent loosening or accidental detachment during handheld shooting, travel, or fast-paced street photography.

For GR IIIx users who rely on the camera’s speed and portability, the secure locking design provides the confidence needed for everyday shooting.

Macro Mode Compatible

The NiSi PR-10 Wide Conversion Lens is fully compatible with the Ricoh GR IIIx Macro Mode. This allows you to shoot close-up subjects without removing the conversion lens, keeping your workflow fast and flexible.

From details and textures to food, flowers, objects, and travel scenes, you can move between wider framing and close-up compositions with less interruption.

Advanced Anti-Reflective Nano Coating

The wide conversion lens features NiSi’s multi-layer anti-reflective nano coating to help minimise flare, ghosting, and internal reflections. This is particularly useful when shooting into strong light, reflective environments, or night scenes with bright light sources.

The coating helps maintain image clarity, contrast, and colour accuracy, allowing the GR IIIx to retain the clean image quality photographers expect.

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 IIIx two practical shooting setups: use the wide conversion lens when you want an approximately 31mm equivalent field of view, or remove it and use standard 49mm filters when you want light control, protection, or creative filter effects.

Premium Aluminum Alloy Construction

The NiSi Wide Conversion Lens features a durable aluminum alloy frame for strength, low weight, and long-term reliability. Front and rear metal lens caps are included to protect the optics from dust and scratches when stored.

The included adapter is also made from durable aluminum alloy, giving the kit a solid, premium feel that suits daily carry, travel, and professional use.

Full Camera Functionality Retained

The kit does not interfere with normal camera operation. Autofocus, metering, auto exposure, and shooting modes continue to work as expected, allowing the GR IIIx to remain fast, responsive, and ready to shoot.

There is no need for complicated setup or changes to your shooting workflow.

Expand the Creative Range of the GR IIIx

The NiSi Wide Conversion Lens Kit for Ricoh GR IIIx gives photographers a wider, more flexible perspective while preserving the compact handling and image quality that make the GR IIIx such a powerful everyday camera.

By converting the GR IIIx to approximately 31mm equivalent, the kit adds valuable creative flexibility for photographers who want more context, more space, and more versatility from their fixed-lens compact camera.
