Canon is introducing a new Zoom Demand for Digital Drive, the ZSD-300D. This new Digital Zoom Servo Demand for Digital/Analog ENG/EFP Lenses will be able to operate the Shuttle Shot (Shtl), Speed Preset, and Frame Preset (F.P) functions. The ZSD-300D will be connected to the lens via a new one-touch 20-pin connector. All current analog controllers are compatible with Digital Drive lenses. |
