Hello. I'm about to purchase a 7d and 24-70L lens before taking a trip through the Grand Canyon and Page. Is the 24 end of the 24-70 going to be sufficient for Antelope Canyon and/or Horseshoe Bend? If not I'm trying to save money so I'm not sure which of the following options I should go with on the 7d:
1. Use my 18-55 is kit lens from my xti
2. Rent a 10-20mm Canon from an online rental shop for $100
3. Buy the Sigma 10-20 f 4-5.6 for $375 used
4. Buy the Tamron AF 10-24mm f/3.5-4.5 SP Di II LD used for $300 used
Any help or other suggestions are appreciated.
