The KP delivers high-quality imagery through an advanced 24.3MP APS-C CMOS sensor that is designed to create detailed images with minimal noise at sensitivities up to ISO 819200. Guaranteeing maximum resolution, the sensor lacks an anti-aliasing, or optical low-pass, filter though this will cause a higher chance of aliasing and moire. For situations at risk of these artefacts, users can leverage an AA Filter Simulator function that slightly moves the sensor in order to mimic the effects of a physical filter. This sensor combines with the power of the PRIME IV 14-bit image processing engine with accelerator unit to create large images with ease and speed. Improving upon the past generation, the PRIME IV can deliver photographs at up to 7 fps in raw format for up to 8 frames. This processor also helps control numerous advanced features, including Pixel Shift Resolution and more. Durability has always been one of Pentax's strong suits, and the KP is no exception with a magnesium alloy body that is tough and lightweight. Also, the KP is sealed to ensure no rain or dust will take your camera out of commission. The camera is designed to handle freezing temperatures as well, with a rating down to 14°F. This durability is maintained when the optional battery grip is in use, as the grip is also sealed in numerous places.
