The compact snapper features a 1.2-inch thick magnesium frame, along with an 18-megapixel APS-C sensor backed by the manufacturer's latest DIGIC 5 processor.
It also includes a 3-inch touch-screen, and is capable of shooting 4.3 frames per second, with an ISO sensitivity up to ISO 12,800, digitally expandable to ISO 25,600. HD video capture is also supported.
Canon's debut mirrorless camera faces stiff competition from Olympus and Panasonic's Micro Four Thirds devices, Sony's NEX range, and Nikon's 1 J1 and V1.
However, the EOS M has the distinct advantage of being compatible with any Canon lens thanks to the EF-EOS M adaptor accessory, increasing its appeal to photographers who already own a Canon-branded device.
The Canon EOS M will be released in October, priced at £770 with an EF-M 18-55mm lens, or £880 with a 22mm f/2 pancake lens and lens adapter.
With both lenses the package comes to £950, while the adapter alone costs £130.
