Canon EF-S 55-250mm f/4-5.6 IS STM Telephoto Zoom Lens offers high magnification in a compact and lightweight EF-S telephoto
zoom lens with an Optical Image Stabilizer for up to 3.5 equivalent
stops for shake correction. It's created to be the perfect companion lens for the EOS 70D, EOS Rebel SL1
and EOS Rebel T5i Digital SLR cameras, the EF-S 55-250mm f/4-5.6 IS STM
lens expands Canon's line of Stepping Motor (STM) lenses to six models -
the EF-S 18-135mm f/3.5-5.6 IS STM, the EF 40mm f/2.8 STM, EF-S 18-55mm
f/3.5-5.6 IS STM, EF-M 18-55mm f/3.5-5.6 IS STM, EF-M 22mm f/2.0 and
the new EF-S 55-250mm f/4-5.6 IS STM lens. Canon's Stepping Motor
lenses allow for the capture of high-quality still and video images and
reduce motor noise from the lens so cameras, such as the new EOS 70D,
will capture the sound of the video scene being recorded without the
interruption of noise by the focusing motors.
The EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens features one UD
lens element, reducing chromatic aberration throughout the zoom range
for excellent image quality with high resolution and contrast. It
features enhanced lens coatings to help ensure superb color balance
while minimizing ghosting and flare and a 7-blade circular aperture
creates beautiful, soft backgrounds. For outstanding performance, a new
compact six-group zoom system provides a maximum magnification of 0.29x
at the telephoto end. Full-time manual focus is available in AF mode.
The front element does not rotate during focus, which is beneficial when
using polarizing filters. Minimum focusing distance is 2.79 ft./0.85m.
The lens' rear focusing system, high-speed CPU and improved AF algorithm
allow for high-speed autofocusing.
