According to the specs on the F100 it will do 3D Matrix Balance Fill Flash with the SB27 and SB28 flash units. But what about those of us with the SB 26 or even the SB25?? Does Nikon not mention these flash units because they are no longer made, or because the F100 will not be fully functional with the SB26 and SB25?? _______________________________________________________ Get your free, private e-mail at http://mail.excite.com/
