Canon HJ18ex28B IASE A 产品宣传册

Whether you own or plan to buy any Sony 1/2-inch XDCAM HD Camcorder, you’ll want

to make sure it’s outfitted with a Canon HDgc lens. HDgc lenses  deliver HD optical

quality and feature many of Canon’s remarkable high-end advances. The HDgc line’s

lenses for 1/2-inch CCD cameras include: the KH21ex5.7 IRSE (telephoto lens),

the KH10ex3.6 IRSE (wide-angle lens), and the KH16ex5.7 IRSE (standard

lens). Canon’s exclusive Digital “eDrive” is included in all three

of these lenses, and is a principal difference (along with zoom

speed range and a built-in 2X extender) between these

models and the more economical 1/2-inch KH20x6.4 KRS,

KH13x4.5 KRS  and KH19x6.7 KAS lenses.

(available on the 

KH20x6.4 KRS and new 

wide-angle KH13x4.5 KRS ), 

an advanced servo system that

facilitates zooming back and forth

between any two focal length

positions and brings an entirely

new range of value-added creativity

to hand-held acquisition systems.

The KH19x6.7 KAS lens is compatible

with Sony’s Auto-Focus

system.

a new,

smaller drive

unit that not

only

comfortably

fits into the palm

of the user’s hand, but

also improves the feeling of unity between the drive unit and your

hand. These drive units, featuring a grip support and ribbed surface,

are tilted at an ideal angle in order to achieve a better balance and to

provide more comfort and reduce operator fatigue.
