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

Versatile all-in-one replacement for a DSLR or mirrorless camera; Great handling and build; Excellent image quality; Spectacular zoom reach; Swift performance with generous buffer depths; Extremely capable video capture; Comprehensive remote control; Quick-and-easy image sharing
Extremely expensive for a fixed-lens camera; Fairly heavy for fixed-lens camera; Somewhat soft in the corners at wide-angle or tele; Noise reduction intrudes at higher sensitivities; No built-in ND filter; Not as fast when shooting raws; Slow buffer clearing
