With the AF drive control program and high-speed communication matched to each lens, fast shooting is performed with high-precision AF control. The lenses are also compatible with AF-C mode.

Lenses are compatible with in-camera image stabilization. The camera automatically detects the focal length of each lens and optimizes image stabilization performance accordingly.

Full compatibility with in-camera aberration correction (correction of vignetting, chromatic aberration and distortion). Since these corrections are matched to the optical characteristics of the lens, this function takes image quality to an even higher level.

The mount has a special seal, making the lens an excellent choice for shooting in a wide range of conditions.

This service converts the mount specifications of Sigma lenses to those for a different camera body: users can have their favorite lenses matched to the camera body when they want to get a new one in the future. This allows long-term use of their favorite lenses, regardless of the camera system.
