Pixel shift / multi-shot is one of the most sophisticated weapons in the megapixel arms race. What is pixel shift? In short, it drastically increases the native resolution of your camera by anywhere from fourfold to tenfold.
By leveraging the in-body image stabilization (IBIS) systems of modern cameras, pixel shift literally shifts the image sensor multiple times per second to capture more pixels. It then merges these separate frames into a single image – resulting in a much higher resolution image than the camera could take with its native sensor alone.
