The NiSi Ring + Cap Kit for Ricoh GR IV replaces the standard Ricoh GN-3 ring and lens cap with a precision-engineered accessory set made specifically for the Ricoh GR IV.

• 1x NiSi Ring for Ricoh GR IV (Titanium Gray)
• 1x NiSi Ring for Ricoh GR IV (Royal Blue)

Key features

• Complete customization kit: The set includes two premium replacement rings in Royal Blue and Titanium Gray plus a NiSi GR lens cap, so you can personalize your camera while maintaining full functionality.
• Works with NiSi accessories for GR IV: The kit is fully compatible with NiSi and standard GN-3 rings. In addition, it supports the NiSi 49mm Filter Adapter, which gives you flexible filter options when using the GR IV.
• Filter-friendly protection: The lens cap supports many filters mounted on the NiSi adapter, so you can protect the camera even when a filter is in place. However, extra-thick filters like some VNDs and CPLs may not be supported, as they can have a different front diameter.
• Premium build & finish: The rings are crafted from durable aluminum alloy and the cap features a precision coating to match the GR IV’s sleek design and provide a cohesive look.
• Scratch & noise protection: The lens cap incorporates imported damping fabric to prevent scratches and to reduce metal-to-metal noise during installation and removal.
• Enhanced handling: You can install the rings and cap without tools. The stepped edge design improves grip for easier, more secure handling.
• Minimalist design: A subtle unpainted “GR” logo on the cap ensures the accessory blends with the camera without drawing unnecessary attention.

Use cases

Choose this kit when you want to replace the stock GN-3 ring and lens cap with a matching, higher-feel accessory designed for the GR IV. It suits users who want to personalize their camera with color options, protect the lens when filters are attached, or swap rings quickly without tools.
