I have a Sunpak 622 Super Pro flash that I used with my Canon EOS A2. The web site for Sunpak really bites, so I thought I'd ask here. Will the accessories for the A2 also work with the EOS 1Ds? I'm mostly talking about the CA-1AF dedicated module for EOS cameras. I also have the EXT-11 dedicated extension cable. I'm assuming it will work, but want to check before I burn something out. Thanks.
