Canon will next month launch an 11-22mm lens for its compact system camera, the EOS M.

The EF-M 11-22mm f/4-5.6 IS STM, priced £379.99, is designed to deliver the 35mm viewing angle equivalent of an 18-35mm zoom.

It has an 12-elements-in-nine-groups construction, seven diaphragm blades and weighs 220g.

Features also include a full-time manual focus ring and a retractable lens design – claimed to be a first for the EF lens series – which is locked in place by a switch and designed to allow users to retract the lens back into the barrel when not in use.

‘This keeps the body slim and compact, reducing the lens length by 13mm’, said the firm in a statement.

Meanwhile, a built-in Optical Stabilizer delivers a 3-stop shutter speed advantage, according to Canon.

• Canon is set to release a firmware update for the EOS M which it claims will speed up the camera’s hybrid AF system, following feedback from customers. The version 2.0.0 update, which is free, is due for release in mid-June
