EF 300mm f/4L IS USM, EF 200mm f/2.8L II USM and EF 24-85mm f/3.5-4.5 
USM Supplement World's Largest Selection of Autofocus SLR Lenses

NEW ORLEANS, LA., February 20, 1997 ~ Canon U.S.A, Inc. is once again 
expanding its line of EF lenses for EOS cameras with the introduction of 
three new products:  the EF 300mm f/4L IS USM, EF 200mm f/2.8L II USM 
and EF 24-85mm f/3.5-4.5 USM.  These new lenses join 48 other EF-series 
lenses currently available to provide EOS owners with the world's 
largest selection of autofocus SLR lenses.

Canon Adds Popular Image Stabilizer Technology to New EF 300mm f/4L IS USM

Canon made photographic history in 1995 by introducing the world's first 
SLR lens with a built-in image stabilizer, the EF 75-300mm f/4-5.6 IS 
USM.  This lens incorporates innovative technology that measures camera 
shake and corrects it with a built-in compensate optical system.  As a 
result, photographers are able to shoot sharp hand-held photos at 
settings up to two full shutter speeds slower than conventional lenses. 
The market has swiftly and positively embraced this technology, making 
the EF 75-300mm IS lens one of the best-selling models in the history of 
the EF line.

"The overwhelming response to Canon's EF 75-300mm image stabilizing lens 
has confirmed that consumers have a genuine need and desire for this 
type of technology," said Ted Ando, director and general manager for 
Canon's Camera Division.

Following the success of the EF 75-300mm IS, Canon is now introducing 
the second EF lens with a built-in image stabilizer, the EF 300mm f/4L 
IS USM. The new image stabilizing lens uses gyro sensors and a 
counteracting, image-stabilizing group moving in parallel, allowing 
photographers to extend hand-held exposure ranges by up to two full 
shutter speeds.  Moreover, the new lens includes a "mode 2" stabilizer 
switch permitting lens stabilization when follow-focusing or panning 
subjects.  This is especially beneficial for sports, nature and wildlife 

Similar to the existing EF 75-300mm IS lens, the EF 300mm f/4L IS 
incorporates a high-speed, 16-bit microcomputer to control image 
stabilization, autofocus and aperture functions.  When the image 
stabilizer is turned off, a center-locking mechanism secures the image 
stabilizing lens-group. This unique technology dramatically reduces the 
risk of getting blurred images, especially when shooting at long focal 
lengths with slow shutter speeds.

The traditional rule for preventing blurred images when photographing at 
long focal lengths is that the shutter speed be set faster than the 
reciprocal focal length in use.  For example, using a focal length of 
300mm, it is recommended to use a shutter speed of 1/350 second, or 
faster, to achieve sharp results.  Photographers can now enjoy 
photographing with a 300mm focal length lens, hand-held at 1/90 second.

As with all Canon EF fixed focal length lenses, the 300mm f/4L IS lens 
accepts the 1.4x and 2x extenders.  The image stabilizing feature can be 
used in conjunction with the extenders and most EOS System cameras.

New EF 200mm f/2.8L II USM Re-Designed with Detachable Lens Hood
 The EF 200mm f/2.8L II USM replaces the original EF 200mm f/2.8L 
 USM lens which had been available since 1991.  Though optically 
 identical to the original, the newer lens is distinguished by the deep, 
 detachable Bayonet mount lens hood.  This supplied accessory offers 
 greater protection from flare caused by stray light than the small hood 
 built into the original lens.  The EF 200mm f/2.8L II USM shares the 7-
 group, 9-element optical formula of the original lens, with two, ultra-
 low dispersion (UD) glass elements that thoroughly correct chromatic 
 aberration to produce crisp, colorful, high-resolution photos.  
 Autofocus is swift and silent, thanks to an advanced rear-focus optical 
 design and Canon's original ring USM.  A selector switch on the lens 
 barrel allows the photographer to set the usable distance range from 
 either 1.5m/4.9 ft. or 3m/9.8 ft. to infinity.  This feature helps to 
 speed-up AF performance when working with subjects at long range.
 The EF 200mm f/2.8L II USM is also fully compatible with Canon's EF 1.4x 
 and 2x extenders, which provide significantly increased magnification at 
 a minimal increase in size and weight.
 EF 24-85mm f/3.5-4.5 USM Lens is Smallest and Lightest Zoom in its 
 Class; Now Available Separately

 The EF 24-85mm f/3.5-4.5 USM covers a broad range of focal lengths from 
 extreme wide-angle to moderate telephoto in an ultra-compact size.  At a 
 minimum length of just 2-3/4 inches and a weight of just 13 ounces, the 
 EF 24-85mm is the smallest and lightest zoom lens in its class, making 
 it very attractive for photographers who wish to combine small size with 
 high image quality.  The new lens features a sophisticated 12-group, 15-
 element optical formula including a large-diameter aspherical element 
 that improves sharpness while reducing distortion.

 Other features include Canon's original ring USM (Ultrasonic Motor) for 
 high-speed silent AF with full-time manual focus override. Close focus 
 is 0.5m/1.6 ft at all focal lengths.  Previously available exclusively 
 in a silver-finish special version as part of a kit with the EOS IX 
 Advanced Photo System SLR, the new black-finish version will be 
 available separately to all EOS owners as an individual lens.

 The EF 300mm f/4L IS USM weighs 42.3 ounces and measures 8.7 inches in 
 length and will have a suggested list price of $2,500.

 The EF 200mm f/2.8L II USM weighs 26.8 ounces and measures 5-3/8-inches 
 in length will have a suggested list price of $1,280.

 The EF 24-85mm f/3.5-4.5 USM weighs 13 ounces and measures 2-3/4-inches 
 in length at its widest angle.  It has a suggested list price of $620.  
 All three lenses will be available at dealers nationwide in March.
