Review Excerpt

Excellent image quality similar to Rebel T4i, T5i and SL1 DSLRs, with 18-megapixel APS-C-type sensor delivering considerable resolution for a mirrorless camera; Solid build and sleek design; Bright, high-resolution 3-inch LCD touchscreen monitor; Full 1080p HD video recording that's virtually silent with an STM lens.
Barely acceptable autofocus speed still lags far behind most mirrorless cameras despite firmware update fix; Limited physical controls and buttons, including no Program, Priority, or Manual on Mode dial; Lacks built-in flash or electronic viewfinder option; Only two compact EF-M mount lenses currently available.
Read our Canon EOS M Review

Pocket-friendly design; Popup electronic viewfinder; Bright lens across the zoom range; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; Wi-Fi wireless networking
Feels a little unbalanced without an accessory grip; Not as much telephoto reach as its siblings; Noise processing is heavier-handed than in earlier models; Quite pricey for a fixed-lens camera
