About the AP-612

The AP-612 Replacement Foot fits the Sony 300 f/2.8 GM OSS FE lenses and serves three main purposes:

Added Stiffness over the factory tripod mounting foot connected to a lens plate, reducing flex and vibration.
Functions as the Arca-Swiss style quick-release plate for your lens.
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.

Installation And Using Instructions

Installation Instructions

Remove the factory foot from the lens.
Attach the AP-612 plate to the lens using the enclosed 1/4-20 x 9/16”L flat head fastener (Fig. 1).
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 or damage the threaded insert on the lens with the hex key included.
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.

Using Flash Brackets

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 the Optional Safety-Stop Screws

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).

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

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.

3rd Party Clamp Warning

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.
