Probably ROLANPRO Waterproof Lens Cover Compatible with Canon RF 200-800mm F6.3-9 IS USM Lens Cover I obtained this from a used camera, but I haven't actually attached it, so I'm saying "probably." Please check the photos for confirmation. - Brand: ROLANPRO - Type: Zoom Lens - Function Ring: Independently rotatable - Lens Hood: Can be stored in reverse - Camouflage Design: Design that blends into the natural environment Easy to attach and remove: Sleeve type for quick attachment and detachment. Smooth access to buttons and dials, without compromising operability or shooting efficiency. Camouflage color for high concealment: Disrupts the outline of the lens outdoors, reducing the subject's wariness. Waterproof rubber cap x camouflage pattern further enhances the blind effect. Full protection & tight fit: Guards against sand, dust, water droplets, impact, and scratches. The tight design prevents slippage, and provides a comfortable, integrated feel after installation. Two-layer structure for waterproof and stain resistance: Surface: Waterproof Oxford/twill fabric. Inside: Non-slip PU + soft brushed lining. Combines cushioning and waterproof properties. Safe materials, no odor, safe to use. Lightweight design & notes on use: Lightweight and easy to carry. It's a bit tight when attaching to ensure a secure fit, but it fits stably after installation. Due to the split structure, we recommend using a one-piece rain cover for long periods of shooting in rainy weather. Thank you for viewing.
