I am considering renting a couple high end lenses for upcoming photo shoots.  $50 for a three day rental is much easier to swallow than $1,800 for a lens.  As of right now I have a standard 18-55mm kit lens, a 50mm f1.8, a 20mm f1.8 macro lens, and a 70-300mm.  I prefer to shoot with my macro lens most of the time do get those little details.  I think a 18-135mm would be a nice addition. If anyone has any experience with this site please let me know.
