Pentax K-3 is the flagship APSC-DSLR by Ricoh Imaging introduced in 2014. Like its predecessor (K-5 II/IIs) it has a magnesium alloy body and weather sealing. Among the improvements from the K-5 II are improved resolution, larger display, and better weather sealing and AF system. The native shake reduction system from Pentax has a mode that detects panning and thus produces stabilized images.

An improved version, called K-3 II, was launched in 2015, and while it has the same sensors, its main improvements are built-in GPS instead of the pop-up flash and Pixel-Shift image enhancement[1]. Pixel Shift enhances the resolution of an image, eliminates artifacts, and reduces noise by using microscopic vibrations of the sensor while taking a series of images. The K-3 II was one of only a handful of digital cameras that natively included this technology at their introduction, and it takes four images without closing the shutter, shifting one pixel with each shot. RAW files are 4x the standard size, but the processor manages the conversion.

The third generation of these cameras, Pentax K-3 III, was launched in 2021 with many more improvements.
