K-1 and Tamron 70-200mm AF adjustment

gerardbaron · 03-25-2017, 05:55 AM

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.

Is the k1 firmware up to date? Try to downgrade at v1.30... and let me know

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

Send to Tamron, excellent service

Check your firmware version, just one minute of your time...

Applying to my k-1 the last v1.40 I had the same issue, solved by downgrade to the v1.30... good luck

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

I'm running firmware 1.4 on my K-1 with no issues.
