MUST HAVE REQUIREMENTS:
- A center-ball style ball head with an Arca-Swiss style quick-release (QR) clamp. Some examples of ball heads with this style quick-release are the Arca-Swiss Monoball (B1 and Z1 single pan “SP” model with screw knob & single-groove clamp), Kirk Enterprises BH-1, Markins M20 or Q20, Really Right Stuff BH-55, Graf Studioball, Foba Superball and Acratech. The Sidekick is not compatible with standard Gitzo, Manfrotto and Cullman quick-release plates and clamps. It is not recommended for use with Gitzo’s off-center or Bubble Ball heads. A Wimberley QR clamp can be installed on several specific ball heads to make them compatible – see Wimberley’s website for details.
- A ball head with separate panning base adjustment and ball tension knobs. This allows you to loosen a knob and spin the head 360 degrees when the ball is solidly locked (most large capacity ball heads have this feature).
- A lens with a rotation collar and tripod mounting foot (or hole). The lens mount must be fitted with an appropriately-sized, Arca-Swiss style, quick-release plate or QR replacement foot.
