I have never posted a question like this one before so be gentle. 
We are taking the kids and the grandkids to the Outer Banks in May and I was considering the purchase of the Canon 18-200mm "do it all" zoom. Use would be for the quick vacation type shots that usually run all over the board on required focal lengths.
When we are just walking around and on the beach I really don't want to haul around several lenses at these times ... so I thought this lens might be an option.
If you look at my "Gear List" you can see that I have lots of wonderful Canon "L" glass, but really do not have any single lens that fills this need. I know that there are trade-offs for these ultra zoom lenses. The good stuff will also be going with me for the sunrises, trips to the close by wildlife refuges, etc. (without the thundering herd!)
I am looking for opinions on this lens or the Sigma / Tamron equivalents. Open to suggestions ... Thanks in advance.
