16 years old. Gear and prices may have changed since.

Dedicated FIZ units that control focus, iris, and zoom simultaneously are available from rental houses starting around $380 per day, with prices negotiable.
Multi-channel wireless follow focus systems allow independent control of different functions, while single-channel units limit simultaneous motor operation.
A full-size steadicam rig with RED camera, zoom lens, and three-motor follow focus system requires significant payload capacity and operator experience.
Two-motor or single-motor follow focus solutions can be adequate for many situations, especially when using prime lenses and planning shots to maintain consistent exposure.
Hiring an experienced steadicam operator who brings their own follow focus system is often more cost-effective and reliable than attempting the setup without professional expertise.
Budget-friendly follow focus units like BFD systems can be layered together to add functionality if needed.

Discussion is from 2010 and equipment options may have changed.
Rental availability and pricing are location-dependent.
The decision between single, dual, or triple motor systems depends on specific shot requirements and whether all three functions must change simultaneously.
No definitive answer provided on whether combining zoom, focus, and iris changes in single shots is common practice.
