Canon FPD-400D
Digital Focus Servo Demand for Canon Lens Control Kits
Canon offers a series of servo controllers for Digital Drive lenses. The ZSD-300D (zoom demand), FPD-400D (focus demand) and FPM-420D (focus servo module) are designed to support the Digital Driver’s unique functions.
They are quickly and easily connected to the “Digital Drive” via a 20-pin one-touch type connector. With the Canon FPD-400D, focus servo operational curve can also be selected, unlike a conventional focus demand. Except for the unique digital functions, the digital series of demands is fully compatible with conventional demands although a conversion cable may be required
