This is Canon’s first zoom lens for the EOS M mirrorless cameras and the company has made it compact and lightweight to match the M-series bodies. The lens measures 86.5mm(L) x 60.9mm(D) and weighs about 260g. The lens utilizes a glass-moulded aspherical element offering high-quality images throughout the zoom range. The stepping motor makes auto-focusing smooth and quiet. It also offers an image stabilization function.
