Scheduled to go on sale in early July the new lens extends the range of dedicated lenses for Canon’s only mirrorless camera to date and features a compact and lightweight design to match the camera. It includes a new type of five-group zoom system that utilises short back focus and an aspherical lens. A UD (ultra-low dispersion) lens element is included to correct chromatic aberration. Autofocusing is driven by a stepping motor and lead screw that operates smoothly and quietly, making this lens suitable for recording movies. Fast autofocusing is achieved for shooting stills through a combination of a rear focus system, high-speed CPU and optimised AF algorithm.

The built-in stabiliser provides a claimed 3.5-stop compensation in shutter speeds. Seven aperture blades close to a circular diaphragm for attractive bokeh and the lens design and coatings are optimised to minimise ghosting and flare. For more information, visit www.canon.com.au.
