NiSi PR-10 Wide Conversion Lens for Ricoh GR Series

The NiSi Wide Conversion Lens (PR-10) is a precision-engineered 0.78x wide-angle adapter designed for the Ricoh GR series of compact cameras. Built for street photographers, travel shooters, and creative professionals who want to expand their field of view without sacrificing the GR's legendary image quality, this conversion lens transforms your fixed-lens compact into a wider, more versatile tool for capturing expansive scenes.

Wider Perspectives for GR Shooters
Mounted on the Ricoh GR III or GR IV, the 0.78x conversion factor shifts the native 28mm equivalent lens to an effective 21mm focal length, opening up significantly wider framing for landscapes, architecture, interiors, and environmental portraits.

On the GR IIIx, the 40mm equivalent is brought down to approximately 31mm, delivering a natural wide-angle perspective that suits street photography and documentary work. The wider field of view adds depth and context to every frame without introducing the distortion often associated with dedicated wide-angle lenses.

Seamless Macro Mode Integration
Unlike many third-party conversion lenses, the NiSi PR-10 is fully compatible with the GR series Macro Mode. This means you can switch between wide-angle perspectives and close-up detail shots without removing the lens, streamlining your workflow and ensuring you never miss a moment. The optical design maintains sharpness and contrast even at close focusing distances.

Advanced Anti-Reflective Nano Coating
The lens elements feature NiSi's multi-layer nano coating, which significantly reduces internal reflections, flare, and ghosting. This is particularly valuable when shooting into strong backlight or near bright light sources, where uncoated or poorly coated optics would produce unwanted artifacts. The result is cleaner contrast, richer color saturation, and improved clarity across the frame.

Premium Build Quality
Constructed from precision-machined aluminum alloy, the NiSi Wide Conversion Lens is both lightweight and exceptionally durable. The robust metal housing protects the internal optics from impact and wear, making it a reliable companion for daily street shooting, extended travel, or demanding outdoor conditions. Both the front and rear metal lens caps provide additional protection against scratches and dust when the lens is stored.

Full Camera Functionality Retained
The NiSi PR-10 does not alter or interfere with any camera functions. Autofocus, auto exposure, metering, and all shooting modes continue to operate exactly as intended. There is no need for manual adjustments or firmware settings, making the lens a true plug-and-play accessory that integrates naturally into your shooting routine.

Adapter Required
To mount the NiSi Wide Conversion Lens on your Ricoh GR camera, a compatible NiSi 49mm Filter Adapter is required for each model: GR III, GR IIIx, or GR IV (each sold separately). The adapter replaces the standard lens ring and provides the secure threaded connection needed to attach the conversion lens. Once mounted, the lens sits securely and maintains a clean, integrated profile consistent with the compact design of the GR series.

A Serious Tool for Serious Photographers
Whether you are shooting wide cityscapes, sweeping landscapes, immersive interiors, or candid street scenes, the NiSi Wide Conversion Lens for Ricoh GR Series delivers the wider perspective and optical quality that professionals demand. It extends the creative reach of your GR camera while preserving the handling, speed, and image quality that make the series a favorite among discerning photographers worldwide.
