SIGMA Sony E-mount LensーAF-C Mode

The new SIGMA Art line prime lenses for Sony E-mount full frame camera system are compatible with Sony’s AF-C (Continuous AF) mode, which is not available when using SIGMA’s Canon and SIGMA mount lenses via MC-11.

These lenses are optimized to all AF systems making the operation of AF feel much smoother and quieter, perfect for a wider variety of customers including those who use Sony E-mount cameras mainly for video shooting.


The face-priority AF shifts to eye AF rapidly when the subject comes near to the camera. The compatibility with Sony’s AF-C mode ensures nimble tracking of moving subjects.


The AF shifts to face-priority AF instantly when the subject moves in from outside the frame and turns to face the camera.
