Tamron has sent a notice out to all its customers warning that it is investigating a compatibility issue with its lenses and the Nikon Z7 and FTZ adapter.
The company hasn’t provided many details about the ‘issues’ it has discovered. It posted the following statement on its website:
Notice about compatibility for Nikon Z7 with Tamron lenses
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 be operational properly on Nikon Z7, which was newly released on September 28, 2018, with Nikon Mount Adapter FTZ.
We are in process to search for the causes and will make further announcement of the compatibility for every single model once we find the solution.
