The Wimberley Sidekick attaches to a ballhead, converting it into a gimbal head for use with large telephoto lenses. The ballhead used must have an Arca-Swiss type quick release plate. We recommended using them for lenses up to 500mm f4 IS and smaller telephoto lenses. Keep in mind the ballhead must be pretty heavy duty, such as the Markins Q20 Heavy Duty Ballhead w/ Knob Release.
Please Note: This item does not include an arca-swiss type plate, which is required to use this tripod head. We do rent the plates separately, but the size plate you’ll need will vary depending on what size lens you’re using. We rent 4 different sizes to give you the most flexibility.
