Ok, but I still think Tamron is partly at fault (design wise) as my humble Nikon 24-120 doesn't have this problem and i don't think it's a common occurence with other lenses either.
maybe you might want to try shooting under the same lighting condition with your Nikon lens at 1/1600 shutter and see if you get the same result. I know i do get it with my canon lens.
