The Kirk NC-300 Replacement Lens Collar is specifically designed for the Nikon 300mm f/4 AF-S lens. It is designed to provide maximum lens support, with quick, accurate, smooth rotation and positive locking in any position.
Precisely machined from lightweight 6061T6 aluminum, the base is made to fit a Kirk Arca Swiss-type quick release clamp. In addition, instead of only one point of support, the NC-300 provides an additional point of support for the lens at the other end of its plate.
- Smoother rotation
- Easier grip and larger locking knob
