In order to use a single SB-800 off-camera with a D2H, a cord is needed (unlike the D70 which can use the "Commander mode" and control the flash in iTTL mode. Now, which cord makes the most sense: the SC-28 (or SC-29 for the built-in AF assist illuminator), or the SC-11, which is a PC-sync cord? The SC-11 is much shorter (convenient for a flash bracket) and much cheaper... But can it be used the same way (save for the AF assist)? I haven't really found the answer: can one use iTTL mode with the SC-11, or is a SC29/28 needed for that? If the SC-11 can't be used for this application, what is it good for and/or how does one go about using it? It looks like the SC-15 is the same thing as the SC-11, except much longer... so I have the feeling that it has to do with multiple lights, when not using the SB-800 wireless system... Thanks much in advance!
