 Notice to end users of Sigma's HSM equipped lenses with the Nikon D200 Camera

To our valued customers,

Sigma HSM equipped lenses do not operate when the "AF operation button" on the back of the body of Nikon "D200" digital SLR camera (recently introduced to the market by Nikon) is used. We have determined that this problem is caused by a firmware "bug" in our HSM equipped lenses.

We deeply regret any inconvenience this may cause our customers who own D200 cameras and we are committed to correcting this situation. We will start updating the firmware of these lenses free of charge in the near future.

Please contact your nearest authorized Sigma Service Center for further information >>

Please also note that if the camera's shutterbug is used for AF operation of HSM equipped lenses, such camera and lens combination functions normally.

This problem occurs with HSM equipped lenses only. Non-HSM models of Sigma lenses function properly with the D200 camera.

Following is a list of HSM equipped lenses which would require an update for the D200 camera:
