The EF-S 10-18mm f/4.5-5.6 IS STM lens combines optical excellence with
cutting-edge performance, providing an ultra-wide angle of view in a compact,
portable package, perfect for EOS cameras with an APS-C sensor. It has a 4 group
optical zoom system and includes a large-diameter element, an aspherical lens
element, a UD lens element and enhanced lens coatings for high-contrast,
high-resolution images with minimal glare and aberration. A circular, 7-blade
aperture helps ensure fine background blur and the Canon Optical Image
Stabilizer system provides up to four equivalent stops of shake correction.
The lens has a stepping motor (STM) and a refined focus mechanism for smooth
and continuous AF during video recording. It also has a rear focusing system,
plus a high speed CPU and improved AF algorithm for high-speed AF; and offers
full-time manual focus for quick adjustments. The EF-S 10-18mm f/4.5-5.6 IS STM
delivers reliable, speedy and quiet wide-angle performance, making it an ideal
lens for everyday photography, travel, stills and video recording.
