Tamron 150-500mm F5-6.7 DI III VC VXD Lens for Nikon Z mount is coming. According to German retailer, this new lens costs 1,399 euros, which is 200 euros more than Sony E-mount and Fujifilm X-mount versions of the same lens.
German retailer Leistenschneider is currently accepting pre-orders for the Tamron 150-500mm F/5-6.7 Di III VC VXD for Z mount, which does not yet exist.
Certainly, if it was a simple listing error on the website, there is a high possibility that the price would be the same as Sony E mount. It will be interesting to see if Tamron makes an official announcement very soon.
