Canon's dedicated grip for the EOS R5, R5 C, R6 and R6 Mark II, holding two LP-E6 series batteries to roughly double the shooting you get from a single cell. A duplicated shutter release, dials and controls make portrait-orientation work far more comfortable, and the extended body balances larger telephoto lenses. Built to the same weather-resistant standard as the camera bodies, so it does not become the weak point in bad conditions.
