Canon RF135mm F1.8 L IS USM Lens
The RF135mm F1.8 L IS USM is a fast telephoto prime built for portrait, wedding, and event shooters who want tight compression and a razor-thin plane of focus. Wide open at f/1.8 it isolates a subject cleanly against a soft, creamy background, and a 17-element formula with three UD elements holds sharpness and controls color fringing right from the maximum aperture. A 9-blade aperture keeps out-of-focus highlights round and clean.
Dual Nano USM drives autofocus quickly and quietly for both stills and video, and optical image stabilization steadies the long focal length for handheld shooting in low light. It focuses as close as 0.7 m for a 0.26x magnification, tighter than most 135mm primes, and uses common 82mm filters. At roughly 935 g it balances well on EOS R bodies for all-day portrait work.
