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
Read our Pentax K-3 Review

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.
