Thank you for purchasing and using our products.
When using AF-S mode and shooting in telephoto range, it could occasionally display the shot is in focus, although it may not be spotted properly on the subject.
We are afraid of this inconvenience caused to the customers who use these products.
We are now investigating the phenomenon and will make a further announcement on the website shortly.
We appreciate your continued support for our company.
For further information, please contact your nearest authorized SIGMA subsidiary / distributor.
