Zoom controllers from VariZoom, Libec, and Bebob can all work with steadicam rigs, though operating a zoom controller while maintaining steadicam stability requires practice and experience.
Bebob controllers support both LANC and Panasonic protocols, providing compatibility with Sony, Panasonic, and Canon cameras, with full function support on most systems except Panasonic which may be limited to zoom and start/stop.
VariZoom controllers work well for focus, iris, and zoom but are generally considered too demanding to operate simultaneously with steadicam balancing.
Libec controllers are compact and smooth-operating compared to bulkier alternatives, with switchable settings for different lens types like Canon and Fuji.
The stock cable on zoom controllers can be problematic for steadicam use due to bulk and weight, but can be replaced with thinner aftermarket alternatives like Mogami shielded cable.
Bebob controllers from several years ago may not fit newer gimbal handle designs due to larger diameter or incompatible screw spacing.
Some newer Canon digital drive lenses present compatibility issues where certain zoom controllers experience uncontrollable zoom creep.
Zoom functionality on steadicam can create dynamic visual effects during motion shots when properly controlled.

Discussion centers on equipment from around 2009, including older controller models whose current availability and specifications are unknown.
Experience described is primarily with specific camera models mentioned: Canon, Panasonic HVX/HMC, Sony HD, Sony EX1/3, and Fuji broadcast cameras.
Fitment compatibility between controllers and specific gimbal models requires verification for each combination, as handle designs vary.
Cable modifications and workarounds mentioned are anecdotal examples rather than standardized solutions.
The discussion does not establish definitive performance rankings or comprehensive testing across all controller types.
