LAKE SUCCESS, N.Y., August 17, 1995<br><br> Canon U.S.A., Inc. is 
introducing the first interchangeable lens with optical image 
stabilization designated specifically for EOS SLR cameras.  The Canon EF 
75-300mm f/4-5.6IS USM lens uses gyro sensors and a counteracting, 
image-stabilizing lens group moving in parallel to achieve this 
milestone in imaging technology.  Until now, this technology was 
available only in Canon 8mm camcorders, dedicated lenses for its L2 Hi-8 
camcorder and its 12 x 36 IS binoculars.<br><br>
	The new lens allows photographers to extend hand-held exposure 
range by up to two EV steps, allowing greater mobility by avoiding the 
need for a tripod.  Incorporated into an EF lens for the first time, a 
high-speed, 16-bit microcomputer is used to control the image 
stabilizing feature, autofocusing and the aperture.  When the image 
stabilizer is turned off, a center-locking mechanism locks the image 
stabilizing lens-group in place.<br><br>
	"Canon's new Image Stabilizing lens for EOS System cameras 
illustrates the company's commitment to offer the most advanced imaging 
technology to photographers to help them realize their visions through 
photography," said Hank Maeda, vice president and general manager for 
Canon's Camera Division.  "We feel we have developed a lens that will 
answer the needs of thousands of photographers worldwide," Mr. Maeda 
explained. <br><br>
	The new image stabilizing lens 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 should be set faster than the reciprocal focal length in use.  For 
example, using a focal length of 200mm, it is recommended to use a 
shutter speed of 1/250 second or faster to achieve sharp results.  In 
many cases, photographers are forced to reduce the depth-of-field to 
gain a faster shutter speed or to use a tripod in situations where its 
use can become quite cumbersome.<br><br>
	The EF 75-300 f/4-5.6 Image Stabilizing lens allows photographers 
to hand-hold the camera using long focal length lenses up to two stops 
beyond the "focal length = shutter speed" formula.  Photographers can 
now enjoy shooting at a 200mm focal length hand-held at 1/60 second.  
This process is attributed to a 16-bit micro-computer which controls a 
series of gyro sensors and micro-motors designed to shift one of the 
lens groups to compensate for camera shake.  The Image Stabilizing 
feature can be activated and deactivated using a switch located on the 
lens barrel.  The stabilizing effect can actually be viewed through the 
viewfinder.<br><br>
	Powered by Canon's exclusive Ultrasonic (USM) motor for 
autofocusing, the lens is silent and very quick to focus, even in low-
light conditions.  The powerful 4:1 zoom ratio makes it an ideal lens 
for a number of shooting situations including sports, portraits, 
landscapes and photojournalism.  Extended to its maximum focal length, 
the lens provides a magnification of 0.25x making it a good choice for 
close-ups.  The new lens also uses environmentally-safe lead-free glass 
throughout the lens' optical system.<br><br>
	The Canon EF 75-300mm f/4-5.6IS USM Image Stabilization lens 
weighs 23.5 ounces and measures 5-7/16 inches in length.
