Hey all....
I'm a noob that will be going on vacation to grand canyon, vegas, and other places in a couple of months....
I was just wondering which lens I should use for taking shots at grand canyon, or which lens do you recommend me getting before this trip? 
I have these lenses for now:
-50mm 1.4
-55-250 IS
-18-55mm Non-IS Kit
Oh yeah I have an XTI
