The AP-555 Replacement Foot fits a variety of Nikon: AF-S 400/2,8E FL, AF-S 600/4 E, AF-S 800/5,6E FL
Lenses and serves three main purposes:
1. Added Stiffness over the factory tripod mounting foot
connected to a lens plate, reducing flex and vibration.
2. Functions as the Arca-Swiss style quick-release plate
for your lens.
3. Creates a more ideal geometry for using your lens on
the Wimberley Sidemount Head and Sidekick, allowing
the lens to balance optimally.
Wimberley lens plates are compatible with Arca-Swiss style
quick-release clamps such as those made by Wimberley,
Kirk Enterprises, Really Right Stuff, Arca-Swiss, Markins,
and others.
