Affordable high magnification
The powerful, yet reasonably priced, EF 70-300mm f/4-5.6 IS USM
will appeal to nature and sports photographers looking to achieve
sharper images when shooting handheld. When fitted to an EOS camera
containing an APS-C sized sensor, the lens gives an angle of view
roughly equivalent to a 112-480mm lens on a full-frame DSLR.
Image Stabilizer
The EF 70-300mm f/5-5.6 IS USM features a three-stop Image
Stabilizer (IS), making this an ideal lens for handheld work.
Shutter speeds up to three stops slower than would be otherwise
possible can be used with no perceptible increase in image blur.
When panning horizontally, the IS system can be set to correct only
for unwanted vertical shake, and the system switches off when the
camera is mounted on a tripod.
UD lens element
A UD (ultra-low dispersion) glass lens element corrects for
chromatic aberrations and provides high resolution and contrast
throughout the zoom range. Only environmentally friendly lead-free
glass is used in the lens construction.
Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance
contrast. They also reduce flare and ghosting - a common
problem caused by light bouncing off a camera's sensor.
Pleasing background blur
A virtually circular aperture diaphragm, which is controlled
electromagnetically, gives out-of-focus regions a softer, more even
feel, and lets in-focus subjects stand out against a blurred
background.
Ultrasonic focusing
A ultrasonic motor drives autofocus extremely quickly, and in near
silence. Excellent holding torque ensures the point of focus is
reached accurately, without overshooting.
