$500 · Sigma 80-400mm zoom lens for Canon EF with 1.4 Teleconverter

Sigma 80-400mm f4.5-5.6 APO DG and Sigma APO DG 1.4 Teleconverter both for Canon EF lens mount. Auto focus with two levels of image stabilization, zoom lock. Includes lens hood, lens caps, tripod mount and carrying cases for both items. Very clean, optically perfect. Operates like new. $500 for both, but would consider splitting them up. I have a EOS 40D body that I would include for another $50
