Optical construction of 12 elements in 10 groups includes 1 ED lens, 2 high refractive index lenses and 2 aspherical lenses, all finished with a high-definition multi-layer coating for improved image clarity and reduced flare. The fast f/1.7 maximum aperture combined with a 9-blade diaphragm produces smooth, natural bokeh and a soft, artistic background blur that helps the subject stand out. Autofocus is driven by a built-in STM stepping motor delivering strong, precise AF performance and effective tracking; the lens also supports eye/face AF for faster response, lower latency and reduced vibration during operation.
