I find the design quite interesting - in a K-01 kind of way.
Don't get the lights in the grip if they're purely aesthetic, however, since they'll be hidden when held, unless they're a slightly ott activation mechanism? Light sensors recognise that you've picked up the body and start up the camera?

The problem might be (a) the lens itself needs a workshop visit for calibration, and/or (b) because it's a Sigma lens, by which I mean that since Sigma avoid licensing costs by reverse engineering, etc, the lens id might be shared with another of your lenses. If (b), when the Sigma is mounted the camera sets up the lens AF the same as the other lens. If the Sigma is already 'out', then the AF adjustment applied to it would/could make it worse.
Does it focus correctly in LV?
Testing should be done with the lens wide open, and being a zoom it is likely to change through the zoom range, so test (a) only at your preferred focal length and put up with any oof at other points in the zoom range, or (b) at both ends and the middle of the zoom range, then average.
Given the possibility of lens id sharing, one thing you could try is reset/cancel all existing lens adjustments (after making a note of them per lens) and then just try setting up the Sigma.
If there is no other lens data in the camera that could cause confusion with the Sigma, and it is still 'out', this I think would point to the Sigma needing re-calibration by Sigma.

Thanks to everyone who sent me offers. Got one now.

You'll need JIS type screwdrivers, not your normal jewellers type.

Anyone?

Welcome! Hope you enjoy it here.
Don't have a Q myself, although did think about it, not least when viewing the results posted here and elsewhere.

If you're looking for sensor or lens element alignment problems then you need a proper test setup, which I'd suggest is camera/lens on a tripod at 90 degrees to a nice frame-filling brick wall then shoot away in both AF and LV modes, wide-open, before posting results on here.
Make sure you use a spirit level to ensure the lens is square to the wall in both vertical and horizontal planes.

Could be you need to use AF Adjust to 'tune' the lens and body combo.
You'll find plenty of posts here and elsewhere that'll help you.
First, though, post a few of your poor shots here for opinions.

It's difficult to tell on these photos but I don't see any pop up flash which for a entry level camera I would think the type of buyer would want???????????????????
CHEERS Vic.
