The Canon EF 70-300mm f/4-5.6 IS USM telephoto
zoom lens has been developed to meet the high-performance standards that
today's photographers demand. The telephoto effect can make the picture
look compressed or have excellent background blur. At the 300mm focal
length, you can fill the frame with a postcard from 4.9' away. Ideal for
sports, portraiture, animals, etc.
Improved Image Stabilizer Technology
provides up to three stops of "shake" correction, and the
"Mode 2" option stabilizes images while panning with a moving
subject. Compared to the original Canon EF 75-300mm IS zoom lens, this
telephoto lens has faster autofocus, and overall the lens is lighter and
has a smaller diameter than the original.
Key Features
• IS Image Stabilizer
Image Stabilizer allows photographers to use shutter speeds up to 3-stops
slower with no perceptible increase in image blur. For stabilized panning,
IS Mode 2 only corrects for unwanted vertical shake by switching off IS in
the horizontal direction. IS is ideal for low light conditions, fast paced
scenes and for shooting from moving vehicles. IS switches off
automatically when the camera is mounted on a tripod.
• Micro USM Motor
The Micro USM motor uses ultra-sonic frequency vibrations to drive rapid
auto-focus with near-silent operation. Good holding torque ensures there
is no overshoot. A high speed CPU and optimised AF algorithm contribute to
AF speed literally faster than the human eye.
• UD Lens Element
A UD (ultra-low dispersion) glass lens element corrects chromatic
aberration to achieve high resolution and contrast throughout the zoom
range without colour fringing on subject outlines. Only lead free glass is
used in the lens construction.
• Super Spectra Coatings
Optimised Super Spectra lens coatings and lens element shaping suppress
flare and ghosting, more prone to occur with digital cameras due to
reflection off the image sensor. Coatings also help achieve true colour
balance and sharp high contrast images.
• Pleasing Background Blur
Circular aperture (8 blades) provides pleasing background blur.
• Secure Transport
The zoom ring can be locked at the 70mm position, making this lens easy
and more secure to transport.
