What is the sensor size of the Pentax K-1?
The Pentax K-1 is a digital camera that has a full frame sensor at its core. This imager measures 35.9mm in width and 24.0mm in height, so that the total imaging area of the sensor amounts to 862 mm2.
The K-1 provides an image resolution of 36.2 megapixels, based on 7 360 horizontal pixels and 4 912 vertical pixels.
Sensor size comparison with a film slide
The sensor diagonal measures 43.2mm, which gives rise to a format factor (or crop factor) of 1.0. Therefore, the Pentax K-1 is a full-frame camera, as its sensor size corresponds to that of a traditional 35mm film slide or negative.
Sensor specs and performance
The table below compares the sensor specs of the Pentax K-1 to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
