The Wimberley has devised adapters for telephoto lenses that take the place of the tripod collar foot and convert the collar to Arca-style clamp capability without the need for additional quick release plates. Critical mass is reduced & the profile of the lens is lowered, which makes it well suited to use with the Wimberley Sidekick.
Every adapter plate is complete with both 3/8"-16 & 1/4"-20 holes to directly attach the lens directly to a monopod or tripod (without an Arca-style clamp) if desired. Drilled holes necessary to attach any of the flash brackets from Wimberley, Really Right Stuff & Kirk Enterprises are also incorporated into the design. Each adapter comes complete with all the necessary hardware and tools to make the conversion, as well as retaining screws to prevent the lens from falling to the ground should you mistakenly unscrew the clamp.
