  • Three significant technologies converge to produce the new YJ20x8.5B Pro-Video production lens system:
  • Optical Technologies

    Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings - that produce an unsurpassed pristine imaging system. The IFpro logo identifies the deployment of the Internal Focus technology in the lens.

    • Combination of specialized optical materials, contemporary optical design, and multilayer coatings produce the superb imagery
    • Internal Focus - a Canon design innovation that uses a floating optical system to better control chromatic aberrations
    • Minimum Object Distance (MOD) of 0.9 meter (10mm with Macro)
  • Shuttle Shot

    Advanced servo systems introduce entirely new value-added creativity to handheld acquisition systems

    • Servo control that facilitates zooming back and forth between any two focal length positions.
    • In addition to the normal Shuttle Shot button, the feature may also be allocated to either the VTR or RET buttons by means of a DIP switch.
    • Maximum Zoom speed is now faster, 1.2 seconds
  • Mechanical Technologies

    Ergonomic mechanical design that produced this Pro-Video lens
