Helping to support the weight of long, telephoto lenses when shooting from a tripod, this Long Lens Y-Support Package from Really Right Stuff steadies the lens and helps to prevent unwanted shake. This package includes a pair of quick release clamps—a B2-Duo and a B2-mAS Mini—to afford precise control over both the X- and Y-axis points of contact in order to accommodate a wide variety of lens sizes. The two bars—the CB-YS Y-Support and CB-10 Camera Bar—both have Arca-type compatible dovetails for mounting flexibility, and the base CB-10 bar features an engraved index scale for repeatable positioning and a bubble level for accuracy.
