It's likely field curvature, not VC, that's affecting your shots

The Tamron 17-50 VC (mine at least) has nasty field curvature from about 18mm to about 35mm. This makes the edges look out of focus. I first thought it was the VC being on when it didn't, then after studying the issue (with many shots), I concluded that the Tamron 17-50 VC has field curvature, with the focal plane near the edges being closer than the center. For interiors, this can actually help things, but for landscape work (where I noticed it), it's rather nasty. And the field curvature is enough to even affect shots at F/9.

For that reason, my 17-50 VC is now almost exclusively an interior/lowlight lens for me (which it is wonderful at). I bought a Nikon 16-85mm for good light/outdoors work.
