Capture sharp, shake-free images. The lens's integrated optical SteadyShot image stabilization ensures razor-sharp, 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, smooth bokeh. Aspherical lens elements provide minimal distortion, while ED glass elements (extra-low dispersion) ensure outstanding contrast, resolution and colour depth. Internal focusing ensures that the lens barrel does not move, allowing a more compact design, faster autofocus response and shorter minimum focusing distances.
