Only lead free glass is used in the lens construction. Optimised Super Spectra lens coatings and lens element shaping suppress flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help achieve true colour balance and sharp high contrast images. A circular barrel aperture helps to create an attractive, even background blur when isolating a subject at large apertures. The lens's micro USM motor uses ultra-sonic frequency vibrations to drive rapid auto-focus with near-silent operation. Good holding torque ensures there is no overshoot. A high speed CPU and optimised AF algorithm contribute to AF speed literally faster than the human eye.
