Review Excerpt

  • Very good image quality and excellent high ISO performance. Premium build quality. In-body image stabilization. Lots of creative features. Full HD movie capture with manual exposure control.

  • Barely any smaller than a standard SLR, but lacks viewfinder and phase-detect autofocus. Contrast-detect AF is slow and unreliable. Body design is clumsy and uncomfortable. Very slow raw burst shooting.
