Six-Part Composition: The Rolanpro lens coat for Nikon Z 800mm F6.3 VR S is composed of six parts, providing comprehensive protection for your lens. | Seamless Integration: Designed to preserve lens functionality, the lens coat does not affect autofocus or lens hood reverse mounting. All switches and buttons operate normally, ensuring uninterrupted control. | Independent Ring Rotation: Enjoy enhanced flexibility with the lens coat installed, as the function ring, focus ring, and support ring can rotate independently for precise adjustments. | Waterproof and Protective Fabric: The lens coat features a water-repellent ChunYa textile exterior and a non-slip cushioning PU lining, providing reliable moisture resistance and a soft protective layer. | Convenient and Secure Attachment: With a Velcro fastening system, the lens coat is simple to assemble and disassemble. The edges of the openings are wrapped to prevent fraying or detachment. Plus, specific openings on the left side allow direct operation of the L-Fn button, Memory Set button, focus range setting switch, focus mode switch, and L-Fn2 button.
