Hey guys, So after referring to the manual on both my D300 and SB-600, it would appear that the only way I can fire the SB-600 is by using the on-camera flash as the commander. Am I missing something, or is this correct? What would be the best alternative to using the on-camera flash, and without using any wires? Get a SB-800 or 900 and use the SB-600 as a slave? Thanks!
