The Kirk LP-58 Arca-Type Quick Release Lens Plate for Canon f/2.8 400mm Lens is designed to take the place of the original tripod collar foot of a Canon Canon EF 400mm f/2.8L IS II USM lens. It converts the collar to make it directly compatible with Arca-type quick release clamps, without the need for additional quick release plates. Critical mass is also reduced.
Each plate comes complete with all the necessary hardware and tools to make the conversion.
Machined from 6061T6 aluminum, and anodized to an unscratchable black satin finish
