I'm visiting Joshua Tree and Death Valley National Parks for this upcoming mid-winter break, and thought about renting a lens for this upcoming trip from LensRentals, but can't really decide which lens to rent, and if I really should be renting a lens. Currently, I only own the kit lens for my 550D (and because I'm a High School student, too poor to buy any lenses, except maybe the 50mm), the lenses I was considering were the 24-70 f/2.8L, or the 24-105 f/4L, but am open to all suggestions. I plan on shooting mainly landscapes (for a stop motion project), maybe some wildlife (if there is any, and I happen to be lucky enough), and some stars.
Thanks in advance for the advice!
edit: I also have looked at the EF-S 17-55mm f/2.8 IS USM, but the cost to rent was more than both of the L lenses. Also, as a side note, is the extra reach of the 24-105 worth the lost f/stop (for the scenario I described above)
edit 2: I recently recieved a REI gift card, and am looking into getting a camera bag, with the lack of gear I currently have, what would you suggest?
