Re: tamron 28-75mm

I bought a 28-75 a week ago, my sample hunts like crazy at 75 mm, almost no matter what lightconditions and contrast I let it AF on. If I zoom out just a little, to maybe 70mm, the AF works well. My testshots have been generally nice and sharp, but they seem to miss on exposure quite a bit, with maybe 30% of the shots underexposed (I have shot with a 1DII in P mode) I see one comment mentioning AF inconsistency at 28mm, mine is very good there...

Should I send it in for service?
