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.
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 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.
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 0.24 meters (0.79 ft.) and maximum magnification of 0.17x mean close-up capability that, combined with the lens’s wide-angle view, can produce dramatic perspectives that also make good use of deep, lush bokeh.
A newly designed high-power DDSSM optimized for this lens, delivers approximately three times greater thrust than the previous focus drive system. The increased power of the new DDSSM system provides faster, more precise, quieter autofocus drive capability, for outstanding performance when shooting stills and movies.
Customizable focus hold button, aperture ring, aperture click switch, Linear Response MF, dust and moisture resistant design, and fluorine front-element coating adds up to fully professional control and reliability for movies as well as stills.
