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"‎‎.‎

Wide‎-angle zoom lens specifically designed for APS‎-C‎-sized sensors provides a 35mm‎-equivalent focal length range of 16‎-28.8mm‎.‎ Four‎-group optical zoom system helps to realize a compact‎,‎ lightweight form factor‎.‎ One UD element‎,‎ one aspherical element‎,‎ and one large‎-diameter element have been incorporated into the optical design to minimize aberrations and distortion throughout the zoom range‎.‎ Enhanced lens coatings have been applied to lens surfaces to reduce flare and ghosting for maintained image contrast and color fidelity‎.‎ An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four stops for improved usability in difficult lighting conditions‎.‎ An STM stepping AF motor realizes smooth‎,‎ near‎-silent autofocus that is complemented by a rear focus system‎,‎ advanced AF algorithms‎,‎ and a high‎-speed CPU for fast AF performance‎.‎ Full‎-time manual focus permits critical focusing precision‎,‎ even in AF mode‎.‎ A seven‎-blade circular diaphragm helps to produces an aesthetic out‎-of‎-focus quality‎.‎
