Review Excerpt

We haven’t finished our review of the Pentax K-50, but we have extensive sample photos and a hands-on report.
See our Pentax K-50 First Shots

Smaller than SLR/CSC with comparable lenses; Larger sensor than other bridge cameras; SLR-like body without the hassle of changing lenses; Weather-sealed; Constant f/2.8 maximum aperture; Generous zoom range; Great viewfinder; Swift performance; Plenty of enthusiast-friendly features including raw shooting; Wi-Fi and NFC wireless sharing.
Expensive compared to other bridge cameras; Menus respond slowly after burst shooting; Lens doesn't zoom very quickly; High ISO performance doesn't quite match RX100 II.
