The Canon RF 135mm f/1.8 L IS USM is a fast telephoto prime lens designed for Canon’s full-frame RF mirrorless camera system. Built around a large f/1.8 maximum aperture, it delivers strong background separation and performs well in low-light conditions. The lens features Canon’s Image Stabilizer system, which works in conjunction with in-body stabilization on compatible camera bodies for reduced camera shake. Autofocus is handled by Canon’s Ultrasonic Motor (USM) for quiet and responsive focusing, making it suitable for both stills and video. Constructed to Canon’s L-series standard, it includes weather sealing and is aimed at portrait, event, and general telephoto photography use.
