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 similar to more expensive DSLRs (like the D7100); Great dynamic range; Responsive all-around performer; Excellent Full HD video-shooting quality; Built-in Wi-Fi with remote control and sharing features; Built-in GPS; Compact and lightweight size; 18-140mm kit lens performs well for its type and has a very versatile focus length range.
