Please mouse over each part of the nomenclature to see it explained.


FEATURES AND TECHNOLOGIES

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
  • A new ergonomic grip specially designed to reduce operator fatigue during long shooting schedules.
