Sorry, I misread the smiley for a happy one. That price is obviously nothing to be happy about.
I don't understand this from Canon BTW. First they make a proprietary cable for their flagship camera- fair enough though slightly annoying and unnecessary. Then they discontinue that camera without keeping some stock of the accessoires? This is a professional camera, come on.
Fortunately I only own the lousy 1N
Nikon did about the same thing for their F5 Photo secretary.
