"The lenses are only incompatible with the 'Quick AF' custom function on the Nikon D200 camera. D200 owners can get the firmware upgraded free of charge if this is a problem."

Sigma lens owners who purchased their lens in the UK can contact service@sigma-imaging.uk.com for further details and to arrange a firmware upgrade.
