Notice to end-users using Sigma's HSM equipped lens with Nikon D200 camera

Sigma has issued a service notice for the use of their HSM lenses on the new Nikon D200 digital SLR. HSM or HyperSonic Motor lenses use a motor driven by ultrasonic waves to provide a quiet, high-speed autofocus (AF). Due to a firmware bug in these lenses, this function does not operate when the AF operation button on the back of the body of Nikon D200 digital SLR is used. In case the shutter button is used for AF operation, the camera and lens combination works without any problem. Sigma is committed to correct this situation and will start updating firmware of these lenses free of charge today...

PRESS SUMMARY

Internet link to the Sigma notice on HSM lenses on the Nikon D200 digtal SLRTo our valued customers,

AF function of our HSM equipped lenses do not operate when "AF operation button" on the back of the body of Nikon "D200" digital SLR camera (recently introduced to the market by Nikon) is used. This problem is caused due to a firmware "bug" of our HSM equipped lenses.

We deeply regret any inconvenience this may cause our customers who own D200 camera and we are committed to making this situation right. In this respect, we will start updating firmware of these lenses free of charge today.

Please also note that if "shutter button" is used for AF operation of HSM equipped lenses, camera and lens combination works without any problem.

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