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 the Sony 24mm f1.4 GM Lens' remarkably light total weight of just 445 grams (15.7 oz.). The reduced size and
the weight of this lens makes it an ideal match for compact E-mount bodies, providing outstanding mobility.
The Sony 24mm f1.4 GM Lens' 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 newly designed high-power DDSSM optimized for the Sony 24mm f1.4 GM 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.
In the Sony 24mm f1.4 GM Lens 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 a 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,
