"1. 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.
2. Compatible with in-camera image stabilization
The lenses will be compatible with in-camera image stabilization. The Sony E-mount camera senses
the focal length of the lens and automatically optimizes image stabilization performance.
3. 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.
4. 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.
5. Available Mount Conversion Service
This service converts the mount of SIGMA lenses to that of a different camera body, allowing photographers to continue using their favorite lenses over the long term regardless of camera system."
