Review Excerpt

  • 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).
