1. Remove the factory foot from the lens. Use the en-

closed hex key to remove all four small mounting screws on
the underside of the lens foot (Fig. 1).

2. Attach the AP-554 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 (see note on page 2).

Made in USA

The AP-554 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.

Using the Optional Safety-Stop Screws

Top Load

(Required with Safety Stop screws)

Safety Stop Channels We recommend using clamps with safety stop channels.

These channels allow a full range of forward and backward motion but will not let

the plate slip out if the clamp is inadvertently loosened.

Wimberley replacement feet have a double dovetail cross-section.
The upper dovetail allows you to attach Wimberley Flash Brackets

as well as other 3rd party quick-release style brackets.

Using Flash Brackets

Top Loading is less convenient,
but you can be certain that your lens
will not slide out of the clamp.

Safety Stop
Channels

Your clamp must have
safety stop channels

3rd Party Clamp Warning: Our safety stop screws work with most 3rd party quick-release clamps, but clamps that do

not have channels and are too wide to be straddled by the safety stop screws will not work.

Arca-Swiss Z1

The safety-stop security
feature of this foot does not work
when used with an Arca-Swiss
“double-decker” quick-release clamp.

If this foot safety feature is important to you, we recommend
replacing the clamp with a Wimberley C-12 QR Clamp.

Thank you for your interest in Wimberley products. If you have any questions or comments please feel free to contact us.

be short enough to allow the
foot to straddle the clamp

Clamps without safety stop
channels (or those without
adequate clearance) will
insecurely clamp the foot
at an angle

Your Wimberley foot comes with two safety stop screws and a matching 2.5mm hex key. Two of these screws are
intended to be screwed into the small bottom threaded holes in the front and back of the foot (Fig. 3) to serve as stops
that prevent the foot from accidentally sliding out of the quick-release clamp. If you opt to use both stops, you must
open the jaws of the quick-release clamp wide enough to load your lens from the top (instead of sliding it in).

Using the AP-554 without using a quick-release

The 3/8 and 1/4 inch holes in the middle section

of the plate can be used to attach the foot
directly to the threaded stud of a

monopod or other lens support
equipment, without needing
a quick-release clamp.

Wimberley plates are also made to accommodate older Really
Right Stuff (RRS) and Kirk screw-mount flash brackets
