The Pentax K-1 is the first production Pentax full-frame digital SLR camera. As the flagship model of the Pentax K-mount system, it includes several new and improved features, including a five-axis SR II in-body image stabilization system, newly designed flexible tilt articulating screen mounted on four metal struts allowing for rotation about the optical axis in addition to upward and downward tilt, and improved autofocus and metering systems.
The camera was officially announced on February 5, 2016,[1] launched on February 17, 2016[2] and first shipped on April 28, 2016.[3]
Ricoh has continued to update the camera after release through free downloadable firmware updates. These have added features including, in v1.40, a night vision mode and a timer for bulb mode.[4]
A Silver Limited Edition was announced on 24 August 2017, with 2000 units available worldwide.[5]
On 22 February 2018, Ricoh announced the Pentax K-1 Mark II with availability from the end of April 2018.[6] Changes and improvements are the use of the newer imaging processing unit from the KP model as well as faster and more accurate autofocus.[7]
In 2018, Pentax offered an upgrade for owners of the K-1 which replaces the mainboard and includes the Image Processing Unit of the K-1 II.[8]
The K-1 achieved the German iF Design Award 2017[9] and Winner status in the German Design Award 2018.[10]
