NiSi Wide Conversion Lens for Ricoh GR3, GR3x & GR4
Mounted on the Ricoh GR III or GR IV, the 0.78x conversion factor shifts the native 28mm-equivalent lens to an effective focal length of 21mm, creating a significantly wider angle of view for landscapes, architecture, interiors, and environmental portraits.
On the GR IIIx, the 40mm-equivalent is reduced to approximately 31mm, delivering a natural wide-angle perspective well suited to street photography and documentary work. The wider angle of view adds depth and context to every image without the distortion commonly associated with dedicated wide-angle lenses.
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-ups without removing the lens, streamlining your workflow and ensuring you never miss a moment. The optical design retains sharpness and contrast even at short focusing distances.
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 artefacts. The result is cleaner contrast, richer colour saturation, and improved clarity across the entire image.
The NiSi wide conversion lens is crafted from precision-machined aluminium alloy, making it both lightweight and exceptionally durable. The robust metal housing protects the internal optics against knocks and wear, making it a reliable companion for everyday street photography, 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 away.
The NiSi PR-10 does not modify or interfere with any camera function. Autofocus, automatic exposure, metering, and all shooting modes continue to work exactly as intended. No manual adjustments or firmware settings are required, making the lens a true plug-and-play accessory that integrates seamlessly 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 firmly in place and maintains a sleek, integrated profile consistent with the compact design of the GR series.
Whether you're capturing sweeping cityscapes, expansive landscapes, immersive interiors, or spontaneous street scenes, the NiSi wide conversion lens for the Ricoh GR series delivers the broader perspective and optical quality that professionals demand. It expands the creative possibilities of your GR camera while preserving the handling, speed, and image quality that have made the series so beloved by discerning photographers worldwide.
