Weight (g) 545 A large-aperture ultra-wide-angle zoom lens with a focal length of 17mm on the wide end. It employs two aspherical lenses, including a ground aspherical lens as the first element, to effectively correct distortion, which tends to occur in wide-angle zoom lenses. The adoption of an inner focusing system maintains high image quality from infinity to the minimum focusing distance. The ring USM is used for AF drive, realizing silent, high-speed AF. Furthermore, the lens is also excellent in usability due to features such as full-time manual focus, which allows manual focusing even in AF mode, and a rear gelatin filter holder.
