Brenda how do you like your Tamron lenses?
I love my 70-200! The VC is insanely good and the af is fast! I don't use the 75-300 much any more. I'm actually considering selling it. It just overlaps in range so much with the other and I don't find myself needing the reach from 200-300 as I am shooting more portraits. It's a good solid lens though.
