A question for Tamron 17-70mm owners

I am in the process of evaluating a new Tamron 17-70mm lens. Among other things I noticed that a X-T2 camera does not report correct focal distances between 17 and 24 mm - it is always 17 mm. Starting with 24 mm and beyond it works fine. Has anyone encountered this?

Another problem (a more serious one) is sharpness. Evaluated the lens both with a test chart and in the field. My 10 year old 18-55 mm Fujifilm lens consistently comes out on top (I do have a good copy!). Most of the reviewers report opposite results. I have attached a couple of comparison shots; the word "mushy" comes to mind when examining the Tamron shots...have to pixel-peep here at 100% to see the difference. Pictures are unprocessed JPEGs out of camera

All pictures were taken with a sturdy tripod using two X-T2s with Fuji and Tamron lenses. Swapping cameras does not help.

Does it look like a bad copy?
