Re: 90d and Tamron 150-600 - sharpness issue or wrong expectations

advice:

I have a sigma 150-600 C lens and and 7D mark II.

I had a sharpness issue when I bought the lens.

I decided to sent the lens and camera to sigma in NY to get calibrated.

This was done at no cost because lens was under warranty.

They made everything right...I note that they fixed things without turning on

the MFA feature in the 7D mark II.  I really don't know exactly what they did...but

it worked.

Moral is it pays to let manufacturer set things up right.  They do know more than

I ever will...now all I have to do is take the photos..
