Severe Inconsistent Focusing Problem

I bought this lens with great excitement because the samples I have seen are fantastic, and most of the reviews I saw were highly positive.

But too bad it wasn't able to focus properly on my Canon 80D.

Because you say "get the USB dock," let me tell you that I did, and it simply could not solve the problem because the focusing issues are inconsistent. For example, at 50mm, one shot is back focused, and the next shot is front focused.

Returning this lens is a huge sorrow to me because the build quality is insane, and also the sharpness is insane (when I got it to focus). Just hope Sigma will make sure their lenses are better calibrated in the future.
