DPReview has a Canon EOS M hands-on preview for those looking for info on the new Canon Mirrorless system.
The EOS M features a compact, magnesium-alloy body, and will be available in four colours - black, white, silver and red. It has no built-in flash, but instead a hot shoe on the top plate, and in many markets (although not the US) it will come bundled with the new AAA-powered Speedlite 90EX unit. There’s neither a built-in viewfinder, nor connector for an external unit - composition is solely using the camera’s rear screen (which is fixed, rather than articulated).
