I'll be in Vegas next week, and will have an opportunity for day trips to Red Rock and the Grand Canyon (aiming for the South Rim). If possible, I'd like to talk the rest of the small group into a Fire Canyon trip.
I have a 6D with a 35 F2 IS and 50mm, but haven't yet picked up a FF general zoom or UW. I have a 60D with the 15-85 and 10-18, but want to travel light.
So, will a FF 35mm and 50mm get the job done, or should I pack the 60D and 10-18 as well (will I be kicking myself if I don't have an UW option?)
I expect the first answer to be "get a 16-35....."
