The lens most likely had some contact issues, my Samyang 2.8/35 behaved the same way. I wiped the contacts of the lens with a clean cloth a few times and all is fine. If it is'nt permanent no need to send it in.

The error permanently returned and the lens wouldn’t work on the A7R2 and A6500. No AF, MF, or aperture control. Thankfully this lens is covered by a fantastic 6 year warranty. I sent it to Tamron last week and they replaced the contacts and sent it back to me right away. Now everything’s working fine.
