Review Excerpt

  • Excellent 18-megapixel sensor with impressively low noise and superb detail; Very good high ISO performance, especially for 18-megapixel subframe sensor; Rugged construction with magnesium body and weather sealing; Fast autofocus and fast burst rate of 8 fps; Full HD (1920x1080) movies at 30/25/24p, 60/50p at 1280x720.

  • No dedicated AF-assist lamp (flash is used), and AF-assist adjustment is buried in the Flash Settings menu; Kit lens (28-135mm) isn't quite up to the resolving power of the 18-megapixel sensor, odd focal length for subframe DSLR; No continuous autofocus in Movie mode.

  • Fast f/2 lens at wide angle; Decent image quality for its class; Excellent waterproof and rugged specs; Solid feature set, including the cool Microscopic Macro function for super closeups; Aperture priority mode; Peppy performance and good battery life; Accepts conversion lenses.

  • Tendency to underexpose shots in Auto mode; Aggressive noise reduction smudges fine detail; Poor video quality with lots of artifacts; No built-in Wi-Fi.
