Review Excerpt

  • Excellent image quality; Good grip; Full HD video recording; Swiveling LCD; Very fast autofocus; HDMI output.

  • Slow frame rate for sports shooting; Tendency to overexpose in bright sunlight; Live View AF is slow; No microfocus adjustment.

  • 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.
