Thanks Randall, I went into a local camera shop yesterday and they had a used Canon 18-200mm lens which I picked up for a pretty good deal, it is far better than the two lenses that I have, but I notice when I am adjusting the focus it has a little stickiness to it, also the lends tends to slid out on its own when I am pointing down on something off the tripod, though it is a Canon lens and I would be probably good with it, I tested both out in the shop and it seamed, at least for movement of the zoom and focal the Tamron was much smoother and seemed more snug and less jerky in it's movements. Is it just that the Canon lens may have more use on it?
Still a Student,
