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

Compact coat-pocket friendly body with plenty of dedicated controls; Great electronic viewfinder; Impressive image quality for its class; Generous performance; Decent battery life.
Too big for a pants pocket; No articulation for LCD; Relatively short zoom range compared to some rivals; Can't use full sensor area at any aspect ratio; Not the best choice for video.
