Canon YJ20x8.5B IRS 20X IF (internal focus) Professional 2/3inch zoom lens with 2X extender

This is a successor to the very popular YJ19x9B IRS and, make no mistake, the Canon YJ19x9B IRS was already a superlative lens, but the new YJ20x8.5B IRS takes Canon and the professional even further.

Yet the higher specifications and improved optical quality have been achieved in an even more compact package: a package, moreover, that is 15.9 mm shorter and 210 grams lighter than leading market rivals.

Improved zoom speed and more...

The YJ20x8.5B IRS has a sector-smashing zoom speed of just 1.2 seconds - an improvement on its own Canon predecessor, and twice as fast as others.

It also offers the shuttle-shot, by having the ability to memorise any two focal lengths of your choice. We've also improved both the optical quality and the ergonomic drive unit. But, despite the changes, the YJ20x8.5B IRS will operate happily with the same operational accessories as its predecessor.

Features:

IF Technology
Pro-Video camera people can take advantage of Canon's breakthrough technology that broadcasters have enjoyed for years-Internal Focus (IF).
Internal Focus technology was pioneered by Canon and first introduced into their Broadcast ENG lenses.
It has since become the industry-standard. Internal Focus is a system where the front end of the lens remains stationary and does not rotate. Only internal elements move when focusing.
 
Internal Focus enhances optical performance and provides several user benefits: 

  • IF improves chromatic aberrations, thus increasing resolution. 
  • IF is not sensitive to change in object distances.  
  • IF decreases flare by use of square food. 
  • IF enables a higher level of creative filter work. 
  • Even heavy optical accessories attached at the end of the Lens does not affect the focusing operation.  

   
New Ergonomic Drive Unit
The new ergonomically designed Drive Unit achieves an ideal balance and comfort by having it tilt to an angle. In addition, the size of the unit has been minimized to comfortably fit in the palm of the hand. Overall, it improves the feeling of unity between the user and the lens.
 
Shuttle Shot Switch
The Shuttle Shot function ON/OFF switch can also be allocated to either the VTR or RET switches by means of a DIP switch.
 
Ribbed Surface
The ribbed surface on the bottom of the Drive Unit provides better handling control.
  
Grip Support
Allows a user to securely grip the Drive Unit without pressing on the VTR or Shuttle Shot buttons.
