    Overview

    The Canon EF 135mm f/2.8 SF is a compact, lightweight telephoto lens with a unique adjustable soft-focus feature. Optically, it is sharp and contrasty when soft-focus is off, but corner sharpness trails center. The soft-focus effect, strongest at f/2.8, adds a dreamy glow but can be overdone. Build quality is plastic, with a loose manual focus ring but fast AF. It suits portrait photographers seeking an in-camera soft-focus effect, though digital post-processing offers similar results.
