The Nikon RT-1 Tripod Mount Ring is an optional accessory tripod collar ring designed specifically for the AF-S NIKKOR 70-200mm f/4G ED VR lens.
When shooting with a D-SLR and the AF-S NIKKOR 70-200mm f/4G ED VR lens, the RT-1 can be used to attach the lens to a tripod instead of attaching the camera's body directly to the tripod.
Attaching the lens to the tripod instead of the D-SLR body can be done when additional support is desired, such as when shooting with a teleconverter.

Due to its weight, when the lens is mounted with a camera on a tripod, the center of gravity is shifted to the lens.
The ring attaches to the tripod and can be shifted to any position on the lens, ensuring the weight is evenly distributedRotation - Having the camera secured with a ring around the lens makes it possible to rotate the lens between landscape and portrait modes without removing the camera from the tripod.
The position of the camera distinguishes portrait or landscape mode, not the position of the lens.
The friction thumbscrews can then be tightened to secure the camera in the desired position. When not needed, the ring can be rotated to an out of the way positionHinged Design - The hinge provides the ability to keep the lens attached to the camera while disconnecting the lens from the tripod.
