There's no doubt that mirrorless cameras are on the up, but one company's been conspicuously late to the party — the world's largest DSLR maker, Canon. That's set to change soon if rumors are to be believed, as an image of a camera called the EOS M has sprung up on Japanese site Digicame Info, which claims it came straight from a retailer. The camera looks to use a new lens mount called EF-M, and is pictured with a 22mm f/2 STM macro lens.

The all-important sensor size remains unclear. Canon Watch's sources claim the EOS M will employ an APS-C sensor, but it's possible that Canon could reuse the slightly smaller 1.5-inch chip found in the G1 X. Otherwise it looks to be a small, simple, and accessible camera — there's no mode dial or viewfinder in sight, and the design is decidedly closer to the Nikon J1 or Panasonic GF5 than the enthusiast-focused Sony NEX-7 or Fujifilm X-Pro1. There doesn't appear to be a pop-up flash, either, though it does have a hotshoe mount. Of course, the image could turn out to be a well-done fake, but with the official reveal said to be coming on Monday we might not have long to find out.
