The JVC Professional HZ-FR15G is a dedicated manual control unit engineered to restore tactile, precise lens operation to JVC's compact GY-HM series camcorders. It addresses a key need for cinematographers and videographers who require fine, repeatable control over focus and iris when using compatible Canon or Fujinon broadcast-style zoom lenses. By connecting directly to the camera's lens port, this module effectively bypasses the default servo-driven controls, providing a traditional manual lens gear system. This allows operators to execute smooth focus pulls, make subtle iris adjustments, and achieve a more filmic, deliberate shooting style that is often difficult or impossible with small motorized controls.

Constructed with professional ergonomics in mind, the unit features large, durable control wheels with adjustable tension for both focus and iris, giving the operator a direct mechanical feel. Its robust mounting system securely attaches to the camera body, creating an integrated and balanced rig. The HZ-FR15G is specifically designed to unlock the full creative potential of higher-end lenses on JVC's handheld platforms, making it an indispensable tool for documentary production, event filming, and any scenario where critical focus and exposure control are paramount.
