This lens cap is custom-designed for the Ricoh GR IV (GR4) camera, ensuring a perfect fit and excellent compatibility. Crafted from premium aluminum alloy and genuine leather, it offers durable, all-around protection against scratches, dust, and accidental impacts without adding bulk to your camera. The interior is lined with soft flannel to safeguard the lens surface from scratches. Installation is effortless—simply place the cap directly onto the lens; no rotation is needed. Its non-interference design ensures that the cap smoothly and automatically detaches when the camera is powered on and the lens extends.
