Overview — Pentax K-1

The Pentax K-1 is a full-frame DSLR built around a 36MP full-frame (35mm) sensor paired with a PRIME IV image processor. It supports an ISO range of 100 to 204,800, giving photographers considerable flexibility across a wide range of lighting conditions. The camera uses the Pentax K lens mount, opening it up to a broad ecosystem of Pentax-compatible glass.

Autofocus is handled by a phase-detection system with 33 points, 25 of which are cross-type, delivering solid subject acquisition performance in the optical viewfinder — an eye-level pentaprism design. For keeping shots sharp, the K-1 features 5-Axis In-Body Stabilization, which works with any compatible lens on the mount. The body is fully weather-sealed, making it a dependable option for outdoor and challenging-environment shooting.

Burst shooting reaches 4.4 fps in full-frame mode and 6.5 fps in APS-C crop mode. Storage is handled by dual SD/SDHC/SDXC card slots with UHS-I support. A 3.2-inch tilting LCD with 1,037,000-dot resolution aids with composing from varied angles.

Connectivity includes Wi-Fi, USB, HDMI output, and a microphone jack. Video tops out at 1080p at up to 60fps. The body weighs 1,010g and measures 137 x 110 x 86mm.
