Canon SUPER E20 Manuel utilisateur

A Higher Standard in Studio Lenses

That Will Not Compromise Your Budget

SUPER E20

E20x8B IE 8-160mm 1:1.5

Canon proudly announces the latest addition to our line of economical yet high quality studio lenses, “SUPER E20”. The “SUPER

E20”, also known as the E20X8BIE, incorporates many of the same features and functions as the J20 Super, the standard of the

broadcast industry with more than 2000 units sold worldwide.

Those features include our exclusive “IF” Internal Focus System and the optional “CROSSOVER” System for seamless 4X3 and

16X9 production on switchable cameras.

When used in conjunction with portable cameras, the “SUPER E20” features a unique Built In Supporter for the lens and camera

combination.

HIGH MTF PERFORMANCE

The height of the 16:9 format is 20%

shorter than that of the current 4:3

format, thus the scanning lines are 20%

greater. As a result, higher resolution is

required for the 16:9 format. In order to

achieve this, the "SUPER E20" Provides

minimum aberrations by the employ-

ment of 3 group IF (Internal Focusing),

Hi-UD glasses (High Index Ultra Low

Dispersion glass) and Canon's unique

fluorite. The "SUPER E20" succeeds in

having higher MTF performance,

correspondent to 6MHz, that is

necessary for the 16:9 format.

3 Group Internal Focusing

In Canon's unique IF system, the front

section is divided into three groups-

concave, convex convex-and the middle

lens moves for focusing. (Fig.1)

By employing the 3 group IF system, the

lens can achieve minimized variation

of aberrations while focusing, minimized

distortion and a high optical performance

even though SUPER E20 has a wide

angle thats starts from 8mm.

CANON"CROSSOVER"SYSTEM

All the Super series of lenses, including

the new SUPER E20 are now optionally

available with "CROSSOVER" compat-

ibility for most 16:9/4:3. The 4 position

extender turret incorporates a 0.8x

"CROSSOVER" unit in addition to the

normal extenders i.e. 1.0x, 1.5x, or 2.0x

(Fig.2). When the camera switches to the

4:3 mode, the extender turret rotates to

the 0.8x position. The 0.8x

"CROSSOVER" unit reduces the

diameter of the image from 11mm to

9mm thus shortening the focal length to

produce an identical picture angle of

view.Inessence,the 0.8x"CROSSOVER"

unit acts as a 1.0x extender for the

switched 4:3 aspect ratio. (Fig.3)

Note ; SUPER E20 for 1/2 inch cameras is also available.
