Large-sensor image quality. Sharp lens with useful zoom range. Tilt/swivel LCD. Twin dials. Smaller than competing interchangeable-lens cameras with a similar lens. Lots of photographer-friendly features.
Not as small as you might hope. Mediocre burst shooting and autofocus speed. Far too easy to accidentally change exposure compensation. Viewfinder is of surprisingly little use. Battery life could be better.
Comfortable ergonomics and solid build; Versatile EVF and tilt-swivel, touch-screen LCD; Good image quality; Great performance for its class; New C-RAW format saves on raw file size; 4K video is an M-series first.
Somewhat limited dynamic range; JPEGs a little soft at base ISO, and more so at higher ISOs; Warm white balance under incandescent light; Poor battery life; Raw buffer is still shallow (but C-RAW helps).
