From Tamron:
Dear users and potential purchasers of Tamron interchangeable lenses.
Thank you for using Tamron products and for your continuous support.
We would like to announce that we have discovered issues that some of Tamron Di/Di II series for Nikon mount models may not operate properly on Nikon Z7, which was newly released on September 28, 2018, with Nikon Mount Adapter FTZ.
We are investigating the causes and will make further announcement of the compatibility for every single model once we find the solution.
From Tamron:
Notice about compatibility between Canon EOS-1D X Mark II and Tamron lens products (about functions on Lens aberration correction)
When using a Tamron lens with the newly released Canon EOS-1D X Mark II camera, please turn OFF the “Lens aberration correction” function included in the camera’s menu prior to use.
We wish to notify you that the AF functions of the following interchangeable lenses for Canon, which have been produced before May 11th, 2015 and have not had firmware updates installed by Tamron, do not function in Live View mode when used on the EOS-1D X Mark II which went on sale on April 28th, 2016 in Japan.
