Ronkonkoma, N.Y. - Sigma revealed Tuesday that a free firmware upgrade is available for photographers using Nikon mount Sigma lenses with their Nikon model D5300 cameras.
The company said it has discovered that when paired with the D5300, Sigma Nikon mount lenses containing internal motors do not properly operate the optical stabilization (OS) and Live View Auto Focus functions.
The issue is specific to lenses used with this particular camera.
The free firmware update will be available starting Nov. 20. For discontinued products, Sigma said users should contact their nearest authorized Sigma distributor.
For lenses that are compatible with the SIGMA USB DOCK, users may update their lenses via the Sigma Optimization Pro software.
Sigma customers who own a Nikon D5300 can contact their nearest authorized Sigma distributors, from the provided link, to receive the firmware update.
Going forward, all Nikon mount Sigma lenses leaving the factory will be made fully compatible with the D5300 and will carry a "D5300 compatible" tag, the company said.
