In a few weeks I will be on vacation in California. Will be stopping in Yosemite and then San Francisco. I have been looking at either renting the Canon EF 14mm, Canon 10-22mm, or maybe the Canon 16-35mm. I have done as much research as I can and time is running short, I need to make a decision. With that I am reaching out to anyone who could offer up an opinion. Forget to mention the lens would be used on a Canon 7D and I'm looking at those lenses for landscape shots. Thanks for the help!
