Pentax K-3 Mark III

2021 · 25.73 MP · 23.3 x 15.5 mm · 820 g · 4K 30p (3840 x 2160)

The Pentax K-3 Mark III is an APS-C DSLR for photographers who prefer a bright optical viewfinder and button-rich handling for nature and outdoor work. Three things matter: a 25.7 MP sensor, 5-axis in-body Shake Reduction that works with every K-mount lens, and bursts of up to 12 fps. Autofocus uses a 101-point SAFOX 13 module with 25 cross-type points, and video reaches 4K at 30p. The 820 g body is rated for about 800 shots per charge.
