Query: Not compatible with Canon EOS 7D

Unlike the posting and the description of this product on Amazon, this product is in no way compatible to Canon EOS 7D. The posting on Amazon describess it as suitable for Canon EOS camera, but having received it to day I found out that the conncetor does not match my 7D camera jack. Very disappointed since I have a photoshoot tomorrow and was counting on this. Also, I paid the shipping costs as well. I hope future buyers who own a 7D read this review and I hope the description is corrected on Amazon as soon as possible.
