Canon EOS-1 - Manual (Page 27)

EF80-200 mm //2.8L
is a super wide-angle zoom lens
which remains bright during zooming.
These new L series lenses use
aspherical elements manufactured
with Canon’s high-level polishing
technology in order to achieve an
image quality that is virtually free of
the spherical aberrations that can
cause distortion in large aperture
lenses. The optical system employs a
floating element construction to
compensate aberration alterations
during focusing and ensure high
image quality at all shooting dis­
tances. Good color balance is
attained through the use of a new,
exclusively-developed multi-layer
coating for the high-refractive index
glass. Designed for full-aperture
photography. Canon’s new L series
lenses offer superlative image
quality, brightness and blur effect,
plus great wide-angle coverage with
the EF 20-35mm f/2.8L.

The large aperture EF 80-200mm
f/2.8L features an outstanding
zoom range for high image quality
and superior operability to meet the
needs of professionals. During
zooming the aperture does not
change, making it ideal for a variety
of applications — from outdoor
photos to studio shots that require
flexibility. The optical system con­
sists of three elements of UD glass
that maintain high image quality and
compensate for the chromatic aber­
rations which often occur with large-
aperture telephoto lenses.
