Thanks John and Randall for your input, I appreciate all your insight, I have an out door wedding reception this evening that I am going to help with, I suppose that this will be a great way to test out the 18-200mm Canon Lens.
The Camera shop told me that I could purchase the Tamron and use it over the weekend and if it didn't work out for what I wanted I could bring it back for an exchange, maybe I should have gone that route to feel it out a bit.
The Pictures from the May work train looked pretty good and I was using a 18-55mm on most of the close shots and they did look pretty good, the far away shots were with the 55-300mm, I guess I just need to find a happy medium somewhere.
Still a Student,
Dave
