July 23, 2012 - Canon has announced two lenses for the EF-M mount used for the first time by its EOS M mirrorless camera. The first lenses will be a EF-M 22mm F2.0 STM 'pancake' prime and an EF-M 18-55mm F3.5-5.6 IS STM stabilized standard zoom lens.
Both are built around a STM linear stepping motors to drive focus. The EF-M 22mm F2.0 offers a field-of-view equivalent to a 35mm lens on a 135 film camera, while the 18-55mm offers around 29-88mm equivalent coverage. Both feature metal lens barrels and focus-by-wire manual focus.
In addition to compatibility with Canon’s existing EF lenses1, accessories and Speedlites, the EOS M launches with its own bespoke range of compact accessories. Two new EF-M lenses offer portability and high performance when using the new model – the EF-M 18-55mm f/3.5-5.6 IS STM standard zoom and the EF-M 22mm f/2 STM pancake lens.
Both feature new Stepper Motor technology for exceptionally smooth AF performance, as well as precision Canon optics, while their compact designs offer the perfect form-factor to complement the camera’s pocket-sized body.
