It'll also snap lower-resolution images, which may sound like a step backwards, but the 12.2-megapixel chip should offer superior image quality, along with a sensitivityrangeof ISO 80 through 12, 800.
As a side note, the EOS M offers an image sensitivityrangeof 100 to 25, 600 (up to 12, 800 when capturing video) -- we'll get into that in further detail later on.
