Canon offers its refurbished Canon EF-S 55-250mm f/4-5.6 IS II Telephoto Lens, model no. 2044B002, for $119.99 plus $5 for shipping. That's $24 below the lowest total price we could find for a new unit, although we saw a refurb for $5 less four days ago. It features UD glass, image stabilization, and front and rear lens caps.
Canon offers the factory-refurbished Canon EF 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens, model no. 0345B002, for $259.99 with free shipping. That's tied with our December mention for the lowest total price we've seen. (It's $69 less than the best deal we could find for a new one.) It features improved Image Stabilizer Technology compared to the original Canon EF 75-300mm IS zoom lens, as well as a lighter weight and smaller diameter. A 1-year Canon warranty applies.
