Notice to Sony a77 and a65 owners using Sigma's Sony fitting lenses

After thorough investigation, we have ascertained that auto focusing does not work properly when some Sony fitting Sigma lenses are used with Sony α77 and α65 interchangeable lens digital cameras. To overcome this, we will be supplying a free update to our customers. This phenomenon will only occur with the combination of any lenses listed below and the Sonyα77 or α65. Future production of Sigma lenses for Sony fitting will be fully compatible with these cameras.

We deeply apologize for any inconvenience caused to our customers.
