Review Excerpt

  • Rugged build; Excellent controls; Extremely high resolution; Dual cards; Surprising high ISO performance.

  • Very large files; Slower frame rate; Custom white balance gives a greenish tint; Battery life lower than D700.

  • Excellent image quality on par to more expensive full-frame DSLRs (including the 5D Mark III); Responsive all-around performer; Superior HD video-shooting chops; Built-in Wi-Fi with remote control and sharing features, Built-in GPS and geotagging.

  • Lacks a built-in, pop-up flash; No external headphone jack; Rather basic 11-point autofocus system; Mediocre burst speed.
