Can't wait to see some shots from the 200D.
I'm hoping to have one before the end of the year.
Have you looked at the Sigma lenses?
Price wise I think you will be close to what you have listed above.
I don't have any experience with Tamaron but I don't think you should overlook Sigma.
My 70-300mm was quite a jump from the 200mm for distance.
Now if ya were to look at the 5....nawwwww nevermind
Pentax 18-55mm,Pentax 50-200mm,Sigma 17-70mm,Sigma 70-300mm, Sigma 50-500mm
