Additional Features <Optical Performance>
Canon is proud to introduce the YJ13x6B, which has emerged from Canon’s exceptional
Pro-Video Wide Lens YJ12x6.5B. The new YJ13x6B surpasses Pro-video Wide lenses by
offering the Widest focal length (6mm), the Highest zoom ratio (13x), and the Fastest zoom
speed (1.2 sec from wide end to tele end). In addition to having Canon’s innovative 3-group
Internal Focus (IF) Technology and exclusive Shuttle Shot Function, its new ergonomically
designed drive unit accounts for its ideal balance and comfort.
The Widest Pro-Video Zoom Lens: Setting a New Standard
High and Flat MTF
●
Achieves a higher MTF by increasing the
resolution at the edges and corners of a picture.
Reduced Chromatic
Aberration and Distortion
●
Although chromatic aberration and
distortion are common as a result of
front lens movement, they have been
greatly reduced.
Creative Filter Work
●
Re-indexing is no longer necessary due
to the filter attaching to the front of the
lens and therefore remaining stationary.

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.
