Introduction

The EF 16-35mm f/4L IS USM is a new professional ultra-wide zoom lens for Canon’s full-frame and APS-C DSLRs. Featuring an ultrasonic motor for smooth, precise and quiet continuous auto-focusing, a Subwavelength Coating and an Air Sphere Coating (ASC) on the lens elements to reduce flare and ghosting, and 9 rounded diaphragm blades for smoother bokeh, the weather-resistant Canon EF 24-105mm f/4L IS II USM is ideal for landscape or architecture photography. The Canon EF 16-35mm f/2.8L III USM is available now for £2349 / €2999 / $2199 in the UK, Europe and the USA respectively.
