The RT-1 tripod collar ring enables the AF-S NIKKOR 70–200mm f/4G ED VR lens to be rotated freely through 360-degrees when attached to a camera body. The ring helps improve tripod balance and allows quick, smooth switching between vertical and horizontal orientation when shooting in portrait and landscape format.
