Kirk Replacement Lens Foot for Canon 300mm f/2.8 IS II USM & 400mm f/4 DO IS II USM Lenses

The Replacement Lens Foot from Kirk connects directly to the lens collar mount and locks into place with four stainless steel screws and the included T-hex wrench. The lens foot is specifically designed for the Canon 300mm f/2.8 IS II USM and 400mm f/4 DO IS II USM Lenses and is compatible with most Arca-type clamps and heads. The double-dovetail design allows other Arca-type accessories to attach to the bottom or the top of the foot, and the 6061-T6 aluminum foot has a black anodized finish, which makes it resistant against scratches and corrosion. Additionally, safety stops located on the bottom of the foot prevent the lens from accidentally being pulled out when the clamp is partially open.
