Perfect for portraiture and a range of other subjects, the F1.8 maximum aperture and optical image stabilization provide impressive picture quality, even in low light. Built-in Optical SteadyShot image stabilization within the lens provides smooth, blur-free photos and videos when shooting handheld. Instead of a standard polygon-shaped lens aperture, this lens features a 7-blade circular aperture for more natural, rounded defocusing, or bokeh. The lens has an innovative optical design to achieve clear, high-quality images by effectively minimizing distortion and chromatic aberration. The internal focusing mechanism means the lens barrel doesn’t move, enabling a more compact design, faster autofocus response, and reduced minimum focusing distances.
