Sony 24mm f/1.4 GM Prime - E Mount

The Sony 24mm f/1.4 GM Prime - E Mount lens features 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 class¹, maximizing portability. It also offers fast, precise AF drive, top-level control and reliability. 

This lens features two XA (extreme aspherical) elements in an optical design that meets stringent G Master requirements, contributing 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 minimizes sagittal flare (an unnatural spreading of point light sources that becomes more pronounced towards the image periphery) so that point light sources are accurately reproduced. 

The 24mm f/1.4 features 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), combined with a newly developed DDSSM (Direct Drive SSM) focus drive system to achieve a remarkably light total weight of just 0.98 lb (445 g). The reduced size and weight of this lens makes it an ideal match for compact E-mount bodies. 

The high-power DDSSM 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. A customizable focus hold button, aperture ring, aperture click switch, Linear Response MF, dustproof and moisture-resistant design², and fluorine front-element coating provide professional control and reliability for capturing movies as well as stills.

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' (0.24m) and maximum magnification of 0.17x result in close-up capability that, combined with the wide-angle view of the lens, can produce dramatic perspectives that also make excellent use of deep, attractive bokeh.
