The Replacement Lens Foot for Nikon 70-200mm f/2.8E FL ED VR and AF-S NIKKOR 500mm f/5.6E PF ED VR Lens from Kirk Enterprises attaches directly to the lens collar and locks into place by tightening the locking knob. Moreover, the replacement lens foot is compatible with most Arca-type clamps, ball and gimbal heads. Meanwhile, the double-dovetail design allows Arca-type accessories to attach to the bottom or the top of the foot.
The lens foot is made from 6061-T6 aluminum and has been black and satin silver anodized, which makes it resistant against scratches and corrosion. In addition, safety stops located on the bottom of the foot prevent the lens from accidentally being pulled when the clamp is partially open. The tightening knob on the foot is also captive, which does not allow the knob to come loose from the foot.
