chromatic aberration in my EOS 5D Mark IV with Tamron lens

[stone58]

Late last year I purchased a 5D Mark IV along with a Tamron 150-600 mm zoom . . . the new series. But my pictures aren't clear. I'm experiencing chromatic aberration as well as fuzziness around the subject when I am zoomed out to 600 mm. I have the current software on my camera. Is that a common phenomenon with that lens and camera? Are there "limits" or settings that I need to be aware of?

I am sure they will take care of you. Both Tamron and Sigma have upped their CS.
