Special Purpose Lenses.
16 additional AFD-type EF lenses
cover a wide range of focal
lengths, providing flexibility and
versatility without sacrificing
necessary quality. 7 fixed focal
length lenses from this group will
be of particular interest to
professional photographers:
The 15mm £/2.8 is a full frame
fisheye providing a 180 degree
angle of view on each diagonal. The
optical performance of this new
formula lens exceeds that of the FD
15mm f/2.8, providing increased
resolution as well as reduced
distortion.
The EF 24mm £/2.8 and EF28mm £/2.8
are excellent general purpose wide-
angles. Both lenses have been
updated with new optical formulas
which deliver better performance
than their FD predecessors. The
24mm lens is distinguished by rear
group focusing and an exclusive
scalloped hood while the 28mm lens
employs a glass-molded aspherical
front element for superb quality at
a very pleasant price.
The EF 50mm f/I.8 is the standard
lens for the entire EOS line. With
its light weight, high speed, and
excellent optical performance, you
won't find any other lens which
offers more for your money.
The EF 50mm £/2.5 Compact Macro has
the fastest aperture of any true
macro auto focus lens, making it a
very useful ' dual purpose optic. Its
floating element design provides
optimum performance at all working
distances, with flat-field corner-
to-corner sharpness at all
apertures. The 50/2.5 focuses from
infinity to 1:2 Life Size with no
attachments.

The EF Li£e Size Converter is made
specifically for the EF 50/2.5
Compact Macro lens. Its 4-element
optical formula acts as a close-
focusing 1.4X extender, converting
the effective focal length of the
Macro to 70mm. The focusing range
of the 50/2.5 with the Life Size
Converter extends from 1:4 to Full
Life Size.
The Life Size Converter has the
advantage of increased auto-
focusing speed over other AF
macros. This is particularly useful
with moving subjects such as small
animals or insects where even a
slight change in subject distance
can cause a great change in focus
at the film plane.
The EF 135mm £/2.8 is a high
performance medium telephoto lens
with Soft Focus capability. Its
rear group focusing system is
quick, smooth, and nearly silent.
Tack sharp at its standard setting,
the EF 135/2.8 can be adjusted for
two degrees of soft focus as a
special effect.
