With the new year I know many of you have new cameras and are thinking about new lenses. Some of the best advice I can give is to rent or borrow any expensive lens before shelling out a lot of money for it. If you have a local camera store sometimes they will credit rentals against an eventual purpose. Otherwise the best pricing and service for online rentals (and local if you're in the San Francisco area) is from borrowlenses.
