The AP-600 Replacement Foot fits 600 f/4 IS III Canon 
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-600 plate to the lens using the four    
enclosed M4 x 14mm 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.
