Canon DR-E4 coupler variable This one's in good cosmeticThe DR E4 is a coupler that allows you to connect an AC E4 power adapter (not included) to a Canon EOS 1Ds Mark III, 1D Mark III, 1D Mark IV, or 1D X (also not included.) Please note: this is the coupler unit only. You will also need to source an AC E4 power adapter to make use of this item. It will not do anything without an AC E4 except give your camera a tail.
