Review Excerpt

  • Top-notch image quality; Great ergonomics in a compact body; Unique on-demand low-pass filtering; Broad sensitivity range; Large and bright viewfinder for an APS-C camera; Dual card slots; Optional Wi-Fi remote control

  • AE Lock button is poorly located; Below-average battery life for a DSLR; Rather dated-looking menu system; Requires a different battery grip accessory than its predecessors; Less third-party support than some rivals

  • 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.

  • AA-filterless sensor makes it more prone to moire; Burst speed slows with highest quality 14-bit RAW images; Live View mode not as good as some competitors; No external headphone jack; GPS receiver not very sensitive.
