This helps optimize camera performance so that you can capture terrific shots of landscapes, family portraits, or sporting tableaus. The responsive Quick-Shift Focus system, meanwhile, makes it easy to instantly shift from autofocus to manual focus. And thanks to the aforementioned ED glass elements, the lens offers superior sharpness and color correction.
