K-1 and Tamron 70-200mm AF adjustment

Yesderday I try to fine tune the AF the Tamron 70-200
-10 and the focus isn't perfect, I am off by 2 line, I was using the viewfinder.
Others lenses adjusted correctly.
Also when I mount the lens on the K-1, I do not get a perfect fit compare to my others lenses.
Is it the K-1 or the Tamron? The Tamron is 2 months old.
What do you suggest?

I have the Tamron and the K-1. They work perfect together no adjustment needed. It is well known about quality issues with the Tamron. If you purchased it new I would send it back if you are within the return period. Otherwise you can send it to Tamron for adjustment. One member here sent their K-1 and Tamron 70-200 into Tamron and was happy with the results.

When I first got my 70-200 the contacts did not line up right, Iactually sent it back twice, the second time with my K-30. They did a good speedy job, paid for all the shipping and it works fine with the K-30 and my K-50. Tamron's service is excellent.

The best solution will be to send the K1+ lens for adjustment...Otherwise just the lens for calibration

As others have indicated, it's not that uncommon for Tamron lenses (not just the 70-200) to be somewhat out of alignment straight from the factory. I've had two brand new 70-200 and one new 28-75 that needed re-alignment from my local Tamron service centre, and another 28-75 in Sony A-mount that needed mount replacement due to a tilting issue (causing the focal plane to be non-parallel to the sensor). I didn't keep the 70-200 lenses as I decided to go with the DA*60-250 (I shoot APS-C with Pentax), but both 28-75 lenses were quickly fixed by the service centre. Following service, they were perfect

Just bought a new K1 last week..... Notice the firmware is 1.0 so would suggest that firmware to 1.30 for Tamron 7-200 f2.8 it is ????

Thanks

About AF fine tuning I had problem using the last firmware 1.4, think before you upgrade.
This is not related to the "not perfect fit" problem reported in the first post, of course
