Nikon Z6-7 with FTZ adapter and Tamron lenses

Anyone here with tamron G2 lenses (24-70 or 70-300) has experience with the FTZ adapter? I wanna know how those lenses perform with the new mirrorless cameras since I’m planning to get the next gen Nikon mirrorless via /r/photography https://ift.tt/2mUqjNu
