Capture sharp, shake-free images. The lens's integrated optical SteadyShot image stabilization ensures crisp, shake-free photos and videos during handheld shooting. Instead of a standard polygonal aperture, this lens features a circular aperture with seven blades for a natural, soft bokeh. Aspherical lens elements minimize distortion, while ED (Extra-low Dispersion) glass elements ensure outstanding contrast, resolution, and color depth. Internal focusing means the lens cylinder does not move, allowing for a more compact design, faster autofocus response, and shorter minimum focusing distances.
