Simply put, this lens of Sony’s G Master TM line is fast. Its f/1.2 lens combines with an 11-blade aperture for stunning bokeh for portraiture and nature photography. That light-gathering ability is coupled with an advanced optical design that delivers a high degree of sharpness and clarity. The inclusion of three XA (extreme aspherical) elements control and virtually eliminate a variety of aberrations, colour fringing and distortion. The Nano AR coating II is applied a for flare and ghosting suppression, important for strong backlit subjects. Four XD Linear motors ensure quiet, precise and rapid AF that benefits both still and video shooting, plus the lens aperture ring can be “de-clicked” for smooth, silent aperture changes during video shooting.
