Canon offers the factory-refurbished Canon EF 50mm f/1.4 USM Autofocus Camera Lens, model no. 2515A003, for $319.99. With $15.99 for shipping, that's $74 under the lowest total price we could find for a new model, although we saw a new model for $22 less last fall. Sales tax is added where applicable. This 10.2-oz. lens is for use with Canon EF-mount SLR cameras. A 90-day Canon warranty applies.
