Thank you very much for purchasing and using Sigma products. Sigma has found that the current firmware of our Nikon mount interchangeable lenses may not work properly with the Nikon D5300’s OS and Live View Auto Focus functions.
For those customers who own Sigma lenses in Nikon mount, Gentec International will provide a free firmware update service. Please note that all products Sigma dispatches from the factory going forward will have the latest firmware and full compatibility.
Nikon D5300 Compatibility
Without the latest firmware, the OS and Live View Auto Focus functions do not work properly when it is used with the Nikon D5300 only.
Concerned Sigma Products
Nikon mount interchangeable lenses that incorporate an internal motor.
* Firmware upgrade cannot be applied to the lenses that do not have an internal focusing motor.
* For some discontinued products, we may not be able to offer the firmware update due to the discontinuation of related repair parts. Please contact Gentec International for the further details.
