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.
