I got my Tamron 150-600 back today, it went in for warranty work.
The report says they changed a switch assembly. The AF on/off switch maybe ?

I went out and took a few test shots, the AF seems to be back to normal.
I haven't readjusted the AF fine-tune, it is still at -2.
Looking at the handheld test shots, I don't think it needs much changing, but I will do some better testing with a target and the camera on a tripod when I get some spare time.
