EF-S 18-135mm f/3.5-5.6 IS USM

The Canon EF-S 18-135mm f/3.5-5.6 IS USM is a versatile zoom lens designed for APS-C-format Canon DSLRs, providing a 28.8-216mm equivalent focal length that covers wide-angle to telephoto perspectives. The lens features a NANO USM autofocus system that combines a ring-type ultrasonic motor with a stepping motor mechanism for quick, accurate, and silent focusing suitable for both photography and video. An optical image stabilizer compensates for up to four stops of camera shake, enabling sharper handheld shooting in challenging lighting conditions.

The optical design incorporates one ultra-low dispersion element and one aspherical element to minimize chromatic and spherical aberrations throughout the zoom range for enhanced clarity and sharpness. Super Spectra coating on individual elements reduces ghosting and flare while maintaining contrast and color neutrality. The lens also features a rounded seven-blade diaphragm that produces pleasing bokeh quality when using selective focus techniques.
