The Nikon RT-1 Tripod Collar Ring for the 70-200mm f/4G Lens is an optional tripod ring designed specifically for the AF-S NIKKOR 70-200mm f/4G ED VR lens. The RT-1 allows you to mount your lens on the tripod rather than attaching the camera's body. This makes it quick and easy to rotate your between portrait or landscape position while also offering additional support and balance.
