What's in this update

It has improved the phenomenon whereby t​he lens’s optical stabilizer effect differs depending on the shutter type and drive mode used. It has corrected the phenomenon whereby the lens firmware cannot be updated via the camera.

  • C​ustomers cannot update to lens firmware Ver.02 by themselves. After the lens has been updated to Ver.02 by SIGMA, the user can then update all future lens firmware via the camera.
