Review Excerpt

  • Very small body, with solid feel; Fast AF; No-nonsense interface. Excellent video capture, Good picture quality.

  • Body could be smaller for sensor size; High ISO isn't as good as other compact system cameras; Battery life below average; Weak flash; Confusing controls.

  • Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Sharp, detailed images with very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.

  • Can seem intimidating at first; Fewer autofocus points than competitors; Doesn't take advantage of high-speed UHS-I flash cards; Movie feature set is very dated and file sizes huge.
