Pentax K-1

Jump to: navigation, search

Pentax K-1 is the flagship full frame digital SLR by Ricoh Imaging introduced in 2016.

The K-1 introduced many improvements over previous cameras. Besides a larger sensor with 36 MP it has a tiltable screen and built-in GPS, Wi-Fi, 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 in astrophotography to follow the stars (Astro-Tracer[1]), simulating an equatorial mount telescope.

An improved version, called K-1 II, was launched in 2018, and while it has the same sensor, it has had many internal improvements, such as Dynamic Pixel-Shift image enhacement, [2] a new processor, extended sensitivity (ISO 819,200) and autofocus algorithms.
