Review Excerpt

Excellent handling in a compact, weather-sealed body; Crisp, roomy electronic viewfinder; Image quality that can take the fight to APS-C DSLRs; Unique high-res mode lets it bat far above its weight for static scenes; Extremely fast 10 fps burst shooting, Excellent video feature set
Control dials are easily bumped; Below-average battery life at default settings; Buffer depths for raw shooters are a bit limited; 16-megapixel sensor resolution feels dated; Weak bundled flash strobe
