Sony To Repair Defective Zeiss 35mm Lenses With Firmware Issues is reporting that some owners of the Sony Zeiss Sonnar T* FE 35mm f/2.8 ZA lens are having problems with the lenses and their camera systems when attempting to perform the company’s recent firmware updates.

According to the site, the bulletin, reposted below, states that some users have been experiencing freezes when updating the firmware, and that the company will be repairing these defective Zeiss 35mm lenses for free.

However, we haven’t been able to confirm this yet with Sony PR and the bulletin posted on the SAR site doesn’t list contact information for affected users to have they releases serviced. We will report as more information is available.
