Review Excerpt

  • Very good image quality at low to moderately high ISOs; Blazing fast single-shot autofocus; Fast 9fps burst with RAW and JPEG files; Built-in Wi-Fi with NFC; Good build quality; Tilting EVF; Articulating touchscreen monitor; Bundled with Adobe Lightroom 5 software; Excellent value.

  • Dynamic range not as good as the best APS-C models; Slow buffer clearing even with fast UHS-I cards; Buffer depth with RAW files is underwhelming; Native lens selection is still fairly limited.
