The Canon FPD-400D is a digital focus servo demand designed for
Canon lens controller kits, including the SS-41-20D, SS-42-20D,
SS-41-IASD, and SS-42-IASD. Compatible with both A- and R-type
lenses, this controller provides precision focus control for a
variety of professional broadcast applications, including live
event coverage and sports. The FPD-400D demand includes a pan-bar
clamp mount but requires a separate cable for both A- and R-type
lenses and a servo module for R-type lenses.
The Canon CR-10 clamper is a mounting device for studio zoom
control for Canon video lenses. This unit works with the ZSG-200A
and ZSG-200M studio zoom controls by mounting the control to a pan
arm on tripod heads.
