Lens recommendations for Canon 7D

[Yago16]

So I will be visiting one camera shop in a slight over a month and would like to see if anybody has any ideas on lenses for me to attempt out while I am down there. I will most possibly be renting one since I just acquired a Canon 7D a couple weeks before and don't have the cash to fall on new lenses too.
Here is what I have:

• Canon 7D
• Canon 17-85 USM IS
• Canon 70-300 USM IS

I was thinking a bit in the broad angle territory for a few good panoramic shots. Anyone have any thoughts or suggestions regarding this?

You have got the ranges enclosed, with the exception of broad angle. So, I would rent either the Canon 10 to 22mm or the Tokina 11 to 16mm 2.8. The Canon 17 to 85mm which you have is a nice walk around lens, but if you wish to rent a 24 to 105mm or a 24 to 70mm, you will find that they do an even improved job.

The 10 to 22mm is what I was thinking but that Tokina seems good too. I would not mind containing a faster lens for dusk shooting anyways. I was in fact kicking around the suggestion of annoying a dissimilar walk around. I do adore my 17 to 85 for the adaptability it gives and it has served me fine for the past 3 years or so, but a quicker lens would absolutely be good. I see one site has the 24 to 70 for a pretty decent cost for a week so I may present that a try as well. Anyone provide any recommendations on places to rent? I have never personally borrowed lenses but a friend suggested one site so I figured I would check them out.

The Tokina 11 to 16 has not at all unsuccessful to amaze me. I don't know how but the colors all the time pop and it is sharp as hell. It is my preferred lens even though it does not go on that much because its use is limited. The Canon 10 to 22 might fit me better as I don't suppose f/2.8 is that serious and the central length might be more appropriate.
