Tamron issues service advisory for lenses used on Canon 5DS, 5DsR cameras

Tamron USA has issued a service advisory regarding select Tamron lenses due to an issue that was causing autofocus issues used on Canon EOS 5DS and 5DSR cameras.

In the advisory, Tamron says, ‘we have learned that the AF functions of the following interchangeable lenses for Canon do not function in Live View mode when used on the EOS 5Ds and EOS 5DsR which went on sale in June 2015.’

Below are a list of the affected lenses:

• SP 15–30mm F/2.8 Di VC USD (Model A012）
• SP 70–200mm F/2.8 Di VC USD (Model A009）
• SP 150–600mm F/5–6.3 Di VC USD (Model A011）
• SP 90mm F/2.8 Di MACRO 1:1 VC USD（Model F004）
• 28–300mm F/3.5–6.3 Di VC PZD (Model A010）
• 16–300mm F/3.5–6.3 Di II VC PZD MACRO (Model B016）

Tamron apologized for the complications in the advisory, noting this is the same issue that plagued EOS Rebel T6s and T6i cameras. Therefore, the same lens firmware update will work for the 5Ds and 5DsR as it did T6s and T6i cameras.

Those who require the firmware update are asked to reach out to Tamron’s service department. Tamron warns that grey-market lenses, such as those purchased from unauthorized Tamron dealers, will not be services.
