Re: Horrible AF Performance with Sigma 150 - 600 Sports and Sony a7r III

If you have not yet, I recommend what XPAT recommended - go to the Sony forum and post there.  I can only speak about the one I have shot and I did a large amount of test shots and  even comparisons to the Sigma 100-400 and it came out on top.  I shot it for landscape and for surfing.  It did a great job with suring images.

It is a possibility that you have a poor copy.  I would put it on a tripod and test it.  Then you can go back to Sigma and will be in a better position to present your case.

Do you know who responded to you ? (name?).  If so, PM (Private Message) to me.

Good Luck

Rick
