To optimize the benefit of the α7R II’s amazing high-resolution capability, especially when shooting unpredictable action or while you’re in motion, the act of shooting should be as steady as possible—otherwise, even slight camera shake can risk blurring the shot. The 5-axis image stabilization system is carefully fine-tuned to match the 42.4-megapixel performance of the α7R II, so you can zoom in on faraway subjects, shoot close-ups and capture night scenes with minimal camera shake blur to achieve maximum clarity.
