I am selling the dc coupler that came with my 1ds mark II. I bought the camera used and I am selling off the parts I don't need. I don't care about having complete kits because I am never getting rid of the camera. I will never use the dc coupler and it appears to have never been used. It works perfectly. I am asking for $60 shipped and paypalled. Reduced to $50 shipped and paypalled. I will also trade for good condition np-e3 battery. Thanks!
