Came off a working 1D MARK III. All buttons work properly. 30 day no questions return policy. Some very minor scratches on top in center, see the last picture. Otherwise in perfect used condition. All functions work properly. Ships out within 24 hours of purchase free to United States and $18 worldwide via USPS First Class mail. See my other listings for working parts for this and other series 1 Canon cameras. Thanks for looking!
