Setup:

1. Installation of the  PX4, PX6 and PX8 Arca Compatible Lens Plates is quick and 

easy! Your package includes (1) Lens Plate (2) 1/4-20 Screws and (3) Allen Keys. The 

smallest key is for removing the safety stop screws explained below, the medium sized 

wrench is for adjusting the anti rotation pins and the other 5/32 key is used to attach the 

screw to the lens plate.

2. Gently cradle your lens with the lens foot facing upwards. Next locate the (2) tall 

anti-rotation screws, this is the top of the plate that lays flat onto your lens foot. You may 

select to put the anti-rotation pins toward the front or back of the lens foot depending on 

the balancing point of your lens / camera combo. The flat top of the lens plate should 

rest flat onto your lens foot of your lens and run parallel with your lens. The anti-rotation 

pins push up against the lens foot and are adjustable for various balance points. 

Now, insert the 1/4-20 screw(s) into the bottom of your lens. Using the supplied allen 

key tighten until snug. Some lenses only require 1 screw and some use both screws. In 

this case slide the plate into a position that will allow access to both screw holes. Using 

2 screws creates 2 points of contact and will eliminate the need to use the anti-rotation 

screws. They may be removed if desired. If 3/-8-16 screws are required for your lens 

they are available to purchase at www.ProMediaGear.com.

3. The PX4, PX6 and PX8 (Updated October 2017) are equipped with our SS2 Quick 

Release Strap Adapter System. This plunger based carrying system is designed around 

a hardened stainless steel insert and allows you to carry your camera and lens with 

ease and confidence.
