We are pleased to inform you that Sigma Imaging UK will provide a free firmware update service for customers who own Sigma lenses in Nikon mount and the Nikon Df digital SLR camera. This is a similar firmware update that is being provided for the Nikon D5300 cameras regarding the OS and Live View Auto Focus functions however for the Nikon Df cameras it includes those lenses that do not have an internal AF motor as shown in the list below.
The firmware update will be provided to Sigma customers as a FREE service and will require the adjustment by our Service Support staff. For our customers that own the latest Global Vision lenses and the Sigma USB Dock, it is possible to download the update using the Sigma Optimization Pro software. This update will be included in all future dispatches from our Japan factory and will be properly marked as D5300 / Df compatible. The firmware updates cannot be applied to some discontinued Sigma products as we may not be able to offer the update due to the unavailability of related repair parts.
