The K-1 introduced many improvements over the previous cameras, besides a larger sensor with 36 MP it has a tiltable screen and built-in GPS, WiFi and Bluetooth. Like most other Pentax DSLRs it has a magnesium alloy body and weather sealing. The internal movement of the Sensor, used for image stabilization is also used to follow the stars (Astro-Tracer) simulating an equatorial mount telescope.

An improved version called K-1 II was launched in 2018 and while having the same sensor, it had many internal improvements such as Dynamic Pixel-Shift image enhacement, new processor, extended sensitivity (ISO 819,200) and AF algorithms.
