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.

  • Super compact and lightweight; Excellent image and print quality that rivals much more expensive CSCs and DSLRs; Solid low-light (high ISO) performance; Touchscreen LCD responsive and useful once you get used to it; Speedy and accurate AF on still subjects; Tons of advanced shooting features and customizing options.

  • Maddening menu system; No physical Mode dial; Motion AF not quite up to par; Mediocre HD video quality; No built-in flash (but a small external flash is included).
