The AP-551 Replacement Foot fits a variety of Nikon
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.
1. Remove the factory foot from the lens. Use the
enclosed hex key to remove all four small mounting screws
on the underside of the lens foot (Fig. 1).
2. Attach the AP-551 plate to the lens using the four
enclosed M3 x 12mm screws (Fig. 2).
3. Drive the screw in until you first meet resistance,
then turn it about 30° farther to establish appropriate, but
not excessive, torque. Do not over tighten; it is possible to
shear the head off the fastener with the hex key included.
4. Install safety stop screws as shown on page 2 (Fig. 3).
Safety stop screws are not required, however they keep
your lens and camera secure when using a compatible QR
clamp.
