Verdict

The Pentax K-S2 is an entry-level DSLR featuring a 20.12-megapixel APS-C CMOS sensor without an anti-aliasing filter, paired with the Prime MII image processor for high sharpness. Its standout characteristics include a fully weather-sealed, dustproof body with over 100 protection points, a 100% field-of-view pentaprism viewfinder, and a 3.0-inch vari-angle 921k-dot LCD screen. Key performance specs include a sensitivity range of ISO 100–51,200, an 11-point SAFOX X autofocus system with 9 cross-type points, and in-body 3.5-stop sensor-shift shake reduction. Main pros are its exceptionally compact, rugged build, built-in Wi-Fi with NFC for remote control, and twin control dials for intuitive manual handling. However, notable cons include poor video quality with limited autofocus, relatively slow startup times, and short battery life compared to other DSLRs in its class.
