The PC-LR Panning clamp is designed to offer precision horizontal panning as a versatile built-in or modular accessory. Combining our patented lever-release clamp jaw with a lockable 360-degree panning bearing, the PC-LR is a robust yet lightweight panning solution for more convenient single-row panorama shooting. Like all of our lever-release clamps, the PC-LR offers the fastest action for quick-release of plates and rails in and out of the jaw. With a patented stainless-steel lever that flips to three positions: closed, half-open, fully-open - you can be confident in the state of the clamp at a glance.
The PC-LR features a built-in dovetail base, allowing you to mount it onto any Really Right Stuff ball head clamp. This allows using the ballhead itself to level the panning axis, thus eliminating the need for a leveling base in many applications. The increased speed and accuracy offered by the panning clamp makes setup for single-row panoramas a snap. When you're done shooting, just slip the panning clamp back into its neoprene pouch (included) and drop it in your camera bag. This quick-release modularity allows part-time panorama shooters to keep the weight off their tripod setup when it's not needed.
For those who prefer not use the dovetail on the bottom, the clamp features a central 3/8"-16 threaded socket, and also includes cap-head 1/4"-20 and M6 screws for mounting directly to Really Right Stuff and Arca-Swiss ball heads.
