Portrait, fashion, wedding and event photographers now have an exciting technology available for enhancing their work in a classic portrait focal length lens. Available in two versions, a standard and DS version incorporating Canon’s new vapor-deposited coating applied on two lens elements, dubbed Defocus Smoothing, has the effect of smoothing the edges of out of focus areas. This results in images made at wider apertures that display smooth bokeh free from bothersome artefacts that are uniquely beautiful.
