The Canon 9519B002 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.
The Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens is a wide-angle zoom lens designed specifically for EOS APS-C DSLRs, where it provides a 35mm-equivalent focal length range of 16-28.8mm. The optical design incorporates one aspherical element, one UD (Ultra-low dispersion) element, and one large-diameter element to minimize chromatic aberrations throughout the zoom range and contribute to notable image sharpness and clarity. Enhanced lens coatings have also been applied to lens elements to minimize lens flare and ghosting for maintained image contrast and color neutrality.
Benefitting working in difficult lighting conditions, an Optical Image Stabilizer has been integrated into the lens design to minimize the appearance of camera shake by up to an effective four shutter speed steps. Pairing well with Canon's EOS Movie Servo AF, an STM stepping AF motor produces smooth, near-silent focusing performance that is further benefitted by a rear-focus design, high-speed CPU, and intelligent AF algorithms for quickened focusing. Full-time manual focus override can also be utilized for fine-tuned focusing precision as closely as 8.7".
