Tamron Issues Canon EOS 5D Mark IV Incompatibility Warnings

From Tamron:
 
Notice about compatibility between Canon EOS 5D Mark IV and Tamron lens products
 
Dear users and potential purchasers of Tamron interchangeable lenses.
 
Thank you for using Tamron products.
 

1. We would like to ask you that, when using a Tamron lens with Canon EOS 5D Mark IV camera that has been released in this September, you turn OFF the “Lens aberration correction” function included in the camera’s menu prior to use.
2. We have learned the issue that when you attach the Tamron SP 90mm F/2.8 Di MACRO 1:1 VC USD (Model F017) on the EOS 5D Mark IV, it takes several seconds to turn on the power of the camera at the first.

We sincerely apologize to all users and potential purchasers for any inconvenience the issue may cause.
