The Pano Elements Packages combine the two basic pieces needed for single-row panorama shooting into one convenient package: a panning device for rotating and a nodal slide for positioning your lens at the proper point to eliminate parallax. This package can mount via its built-in dovetail on top of your ball head or leveling base. 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 to use the dovetail on the bottom, the clamp features a central 3/8"-16 threaded socket and 1/4"-20 screws for mounting directly to RRS Dovetail Standard
compatible ball heads.
