Stay away from Tamron(24-70 f/2.8)

I have Canon 100mm macro, 70-200 f/4 is, 10-22mm, 50mm 1.4, 85mm 1.8 and the Tamron can't compare to any of these lenses. It is by far the worst in the group. I have owned other Tamron lenses through the years and none of them was good. My expectations are not unrealistic, i was expecting the "new" Tamron technology to be good as at least as my 85mm 1.8. Tamron is a total fail, and all of you who are happy with SMUDGED images, good on you. Enjoy your third-party lenses.
