67mm Filter Size f/4.5-5.6 Aperture IS Stabilized EF-S Mount The Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens is a wide-angle zoom lens that 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. Wide Angle Zoom This Canon EF lens is specifically designed for APS-C-sized sensors and provides a 35mm-equivalent focal length range of 16-28.8mm. The four-group optical zoom system helps achieve a compact, lightweight form factor. STM Stepping AF Motor The STM stepping AF motor features smooth, almost-silent autofocus, which is further enhanced by a rear focus system, advanced AF algorithms, and a high-speed CPU for fast AF performance. Optical Image Stabilizer Minimizes the appearance of camera shake by up to four stops for improved usability in difficult lighting conditions. Seven-Blade Circular Diaphragm Helps create an aesthetic out-of-focus or bokeh effect. Manual Focus Full-time manual focus provides crucial focusing precision, even in AF mode. Aspherical Elements One UD element, one aspherical element, and one large-diameter element have been incorporated into the optical design to minimize minimize chromatic aberrations throughout the zoom range, offering better clarity and image sharpness. Enhanced Lens Coating Enhanced lens coatings have been applied to lens surfaces to reduce flare and ghosting to maintain image contrast and color purity.
