The Kirk NC80-400 Replacement Lens Collar is a replacement lens collar specifically designed for the Nikon 80-400mm f/4.5-5.6 VR lens. It is designed to provide maximum lens support, with quick, accurate and smooth rotation, and positive locking in any position.

Precisely machined from lightweight 6061T6 aluminum, the base is made to fit any Acra Swiss-type quick release clamp. In addition, instead of only one point of support, the NC80-400 provides an additional point of support for the lens at the other end of its plate.
