Longer stills battery life

Review Excerpt

Rugged construction; 51-point AF system capable of sophisticated AF tracking; Large, bright optical viewfinder; 7 fps JPEG or 12-bit RAW burst mode; HD Video capture.
14-bit RAW mode slows continuous shooting from 7 fps to 2.7 fps; Somewhat slow AF for a camera at this level, especially in 51-point auto-area mode; Video capture tops out at 720p24.
Read our Nikon D300S Full Review

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
