[QUOTE="WayneF, post: 317010, member: 12496"] Sorry, no. :) The SB-600 does work (and can do TTL) on the SC-28 cord... It is simply a hot shoe extension cord. However the practical length is only maybe four feet, since if stretched longer, the coil tension tends to tip over the light stand. :) However, the simple optical slave still cannot be triggered by TTL flashes either. TTL first involves a low level preflash. The camera meters this preflash, and determines a proper final flash level, and programs the flash power level, which when the shutter opens, then fires at this programmed level. The point is, the TTL preflash will also trigger the simple slave too early, so if TTL is used for the trigger, the slave will fire and expend itself before the shutter opens. Same as the Commander does. A few modern flashes (typically Yongnou and Neewer brands) have two slave modes for manual flash, the regular simple slave called S1 mode, and also a S2 mode designed to ignore TTL preflash, to allow it to work with simple cameras that do not have a manual flash mode. This mode does NOT include the Nikon brand, and unlikely in the older flash too. Otherwise, we simply have to chose what we are doing... either use the Commander system as it is designed, or to use manual flash as it is designed, but mixing systems is not going to work. If you want multiple remote TTL flashes, the answer is to use the commander with commander-compatible flashes, like SB-600, SB-700, SB-800, SB-900. Also, the $100 class [URL="http://www.scantips.com/lights/yongnuo565.html"]Yongnuo YN-565EX[/URL] can do this too, very well. Or you can use ALL manual mode flashes (every flash involved, and no commander) then you can trigger one some other way, and then use simple optical slaves for the rest. Such a way includes a SC-28 cord, or a PC sync cord, or a radio trigger. The simple optical trigger will work with those, if all flashes involved are in Manual flash mode. It is a choice. We simply have to chose one, one and only one system. :) [/QUOTE]
