Interchangeable lenses for the Sony E-mount digital camera series with full-frame image sensors are added as members of the Art line.
While offering the same high-performance optical design as other lenses in the Art line, the new E-mount models will feature a newly developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses will be compatible with Sony’s Continuous AF (AF-C) and high-speed autofocus, which are not addressed by MOUNT CONVERTER MC-11.
Autofocus tuned for each lens
Thanks to an autofocus drive control program tuned for each lens and high-speed data transmission, the lenses will 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
The lenses will be compatible with in-camera image stabilization. The E-mount camera senses the focal length of the lens and automatically optimizes image stabilization performance.
Data loaded for compatibility with in-camera aberration correction
The lenses will be 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.
Native mount for a more rigid and 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.
