This Wooden Camera E-Mount to PL-Mount Adapter for Sony FS7 adapts the E-mount on your FS7 camera to ARRI PL, which allows you to mount available PL mount lenses on your camera. It features a support brace that attaches to your camera by interfacing with an optional Wooden Camera FS7 top plate. Once mounted to the optional FS7 top plate, the support brace relieves the strain of supporting the lens on the mount alone. The unit includes a set of shims to adjust your flange focal distance if necessary and a PL lens port cap to keep your sensor dust free when no lens is attached. Please note that you are able to use the PL adapter on a variety of E-mount cameras; however, the support ring would not provide any support and would not need to be attached.
