Unsparing application of leading-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. This innovative optical design minimises sagittal flare so that point light sources are accurately reproduced.
A new optical design incorporating two precision XA elements suppresses sagittal flare, a common aberration in large-aperture lenses. Sagittal flare can cause an unnatural spreading of point light sources that becomes more pronounced towards the image periphery.
The new design 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 445 grams (15.7 oz.). The reduced size and weight of this lens makes it an ideal match for compact E-mount bodies, providing outstanding mobility.
