Signal-to-noise ratio

Not surprisingly, the Canon M put in a very similar performance to the Canon 650D in our lab tests.

JPEG Files

Canon EOS M review

The JPEGs from the M don't quite match those from the Olympus E-PL5 and the Nikon J2 from ISO 800 upwards, indicating the benefit of shooting raw images (see below) that you process yourself using Canon's excellent Digital Photo Professional software which is supplied or a third-party raw converter.

Canon EOS M review

The M's raw files (after conversion to TIFF) compare well for signal-to-noise ratio with those from the Olympus E-PL5, Panasonic GF5 and Nikon J2.

JPEG Dynamic range

Canon EOS M review

None of the cameras compared here can quite match the Olympus E-PL5 for dynamic range, though the Nikon J2's JPEGs come closest at around ISO 1600-3200.

Canon EOS M review

Raw files (after conversion to TIFF) with a dynamic range of around 12EV at ISO 100, dropping to about 9.5EV at ISO 3200 means the Canon M can certainly hold its own and images have a good tonal range.
