Well with all the discussion and suggestions I received here I traded my Sigma 18-200 for a Canon 28-135 and a few $$. I am extremely happy with the lens.
I am now considering either something in the 10-20 or a prime in the 24 to 30 range. Seems price for either is high.
I am leaning toward the 10-20 for UWA application, but wonder if that lens would limit me too much. So any advice as to a 24 or 30 prime or the 10-20 is greatly appreciated.
