Hey guys.

I bought a good as new Sigma 150 - 600 Sports.

I'm using it nearly daily for 1 month now and I constantly have horrible AF Performance.

Mizzu,

You bought it "good as new".

Did you get a warranty with it from the seller.? If so let the seller take responsibility  for it.

It's possible that a fault had been caused to it from the previous user(s) and was sold on for that reason. AF is not known to be deficient in those lenses.

If you test it on a tripod as suggested make sure to turn off Steady Shot (IBIS) in the camera and also OS on the lens.
