According to Pentax’s description of the feature, “Pixel shift technology uses the camera’s in-body Shake Reduction mechanism to move the image sensor at single pixel increments, capture 4 separate images, which are subsequently combined into a single high definition image. Benefits include higher resolving power, reduced false color and improved overall image quality of non-moving subjects.”
As for the rest of the camera’s specs, the Pentax K-3 II will feature a 24MP APS-C sensor, a 27-point AF system, image stabilization, built-in GPS, a gyro-sensor-based panning detection, and automatic horizon correction. The only thing that seems to be missing is a built-in flash, meaning that photographers will have to get their own flash units.
The body of the Pentax K-3 II has also been designed to be both dustproof and water-resistant and has also been designed to take a bump or two. It is priced at $1,100 and is expected to be made available in the US come May 2015.
