Thanks to an autofocus drive control program tuned for each new Sony FE Art lens and high-speed data transmission, the lenses offer high-speed autofocus at the same performance level as that of a lens designed exclusively for mirrorless cameras. In particular, in E-mount cameras offering Sony’s Fast Hybrid AF, AF-C mode will deliver exceptional subject following performance. Moreover, autofocus will remain extremely precise even in those E-mount cameras offering only contrast AF.
Compatible with in-camera image stabilization
This lens is compatible with Sony's in-camera image stabilization. The E-mount camera senses the focal length of the lens and automatically optimizes image stabilization performance.
Excellent correction of chromatic abberation
The SIGMA 50mm f/1.4 DG HSM Art lens incorporates an SLD (Special Low Dispersion) glass element to minimize chromatic aberration of magnification which is mainly visible around the edge of the image. Moreover the power layout ensures the correction of axial chromatic aberration. Without any color blur, it achieves high image quality throughout the entire focusing range, thus achieving sharp and high contrast image rendering.
Designed to minimise flare & ghosting
Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
Large maximum aperture of f/1.4
This lens achieves extraordinary expressive power at the aperture value of f/1.4. For wide angle photography, it ensures excellent brightness with the large f/1.4 aperture and a beautiful bokeh effect.
Data loaded for compatibility with in-camera aberration correction
This lens is fully compatible with in-camera aberration correction, which includes corrections for peripheral illumination, chromatic aberrations, and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.
Floating inner focusing system
This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance for close-up photos.
Native mount for a more rigid & stable feel
Making the mount native to the lens makes possible a more rigid and stable feel to the lens. Featuring a special surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.
