Review Excerpt

  • Excellent image quality with good color and dynamic range; Great high ISO performance for its class; Extremely speedy performer, with fast and accurate autofocus on stationary subjects; Lightweight, compact and ergonomic design; Touchscreen LCD that tilts all the way forward for taking self portraits; Tons of advanced functions and customizable options.

  • Confusing and frustrating menu system takes hours to master; AF isn't optimal for taking fast-motion action shots; LCD viewfinding suffers under direct sunlight; Mediocre HD video quality; No built-in flash (but a small external flash is included).
