Canon offers its factory-refurbished Canon EF 24-70mm f/2.8L II Zoom Lens, model no. 5175B005, for $1,839.20 with free shipping. That's the first time we've seen this model as a refurb and $111 under the lowest total price we could find for a new unit. It features a 15" minimum focal distance. A 1-year Canon warranty applies, the same as new units.
