NiSi Wide Conversion Lens for Ricoh GR Series (GR III, GR IIIx, GR IV)
Introducing the NiSi Wide Conversion Lens for Ricoh GR Series (GR III, GR IIIx, GR IV), a 0.78x wide-angle conversion lens built for street photography, travel, architecture, and everyday carry when you want a wider frame without giving up the GR’s speed and simplicity. On Ricoh GR III / GR IV, it widens your view to a 21mm equivalent. On the Ricoh GR IIIx, it delivers a 31mm equivalent focal length for a natural wide street look, with more context in every frame. And because it retains Macro Mode and doesn’t interfere with autofocus, metering, or shooting modes, you can keep your normal GR workflow and shoot without compromises. To keep your images clean in harsh light, it features a multi-layer anti-reflective nano coating to reduce flare and ghosting, and it’s built with a durable aluminum alloy frame plus front and rear metal caps for protection in the bag. Adapter Required (Important): To mount this lens, you’ll need the NiSi 49mm Filter Adapter for your specific GR model (sold separately). NiSi Wide Conversion Lens key features:
- 0.78x wide conversion: 28mm→21mm equiv (GR III/IV), 40mm→31mm equiv (GR IIIx)
- Macro Mode compatible + full camera functionality retained (AF, metering, modes)
- Nano coating reduces flare/ghosting for cleaner contrast in tough light
- Aluminum alloy build + metal caps for daily carry protection
NiSi JetMag lens hood kit for Ricoh GR IV
The NiSi JetMag Lens Hood Kit for the Ricoh GR IV is a purpose-built hood-and-adaptor system designed to keep your GR IV setup clean, compact, and ready for everyday carry. Built for street and travel shooters, this kit adds practical protection and better control in harsh light without turning your GR IV into a bulky setup. The result is a more refined, premium look with real functionality you’ll actually use. The included 49mm adaptor lets you use standard 49mm filters (CPL, ND, effects), and its auto-lock keeps everything secure while you shoot. The hood fits right over your filter, allowing you to control flare in harsh light without compromising your creative vision, and the magnetic lens cap snaps on fast for quick protection between shots.
