Unsparing application of cutting-edge technology achieves refined G Master performance with consistently high resolution and soft, natural bokeh even at the widest F1.4 aperture setting. The lens is both compact and the lightest in its class, maximizing portability. It also offers fast, precise AF drive, top-level control and reliability.
Two XA (extreme aspherical) elements in an optical design that meets stringent G Master requirements contribute to consistently high resolution throughout the image area. Three ED (Extra-low Dispersion) glass elements are also included to effectively suppress chromatic aberration. These innovative optical design that minimizes sagittal flare so that point light sources are accurately reproduced.
A new optical design that reduces overall lens diameter by employing two XA elements, one for the front element that is normally the largest in a lens, combines with a newly developed DDSSM (Direct Drive SSM) focus drive system to achieve a remarkably light total weight of just 15.7 oz (445 g). The reduced size and weight of this lens makes it an ideal match for compact E-mount bodies, providing outstanding mobility.
An 11-blade circular aperture enhances soft, natural looking bokeh achieved through advanced design and a manufacturing process that includes precise control of spherical aberration. A minimum focusing distance of 0.79 ft (0.24 m) and maximum magnification of 0.17x mean close-up capability that, combined with the wide-angle view of the lens, can produce dramatic perspectives that also make good use of deep, lush bokeh.
