[QUOTE="WayneF, post: 316193, member: 12496"] Aperture in the flash menu settings are only a factor for the flash A or AA mode, which the SB-700 does not have. That menu has no meaning or significance in flash M or TTL modes, where the power is as programmed. Surprised me too. You said 35mm zoom. Were all three also in the same DX/FX zoom mode too? They would be more equal if SB-900 was FX mode and SB-700 was DX mode, but which would not be a valid comparison of course. You did not say what the precise measured distance was, or then we could have computed guide numbers, to judge if reasonable. :) The SB-900 numbers suggest distance was abut 6.6 feet, but this is a key fact to reveal. The Nikon specs say SB-900 GN is 111.9 (35mm FX) and SB-700 GN is 91.9 (35mm FX). Which says SB-900 should be 1/2 stop stronger (at 35mm FX zoom). [/QUOTE]
