Little Lion, (:-) That the master becomes automatically group A doesn't mean that frontal light will be stronger, as you can set a ratio A:B of 1:8 (max) where you will see little of the effects of A, but it *does* means that you have (almost) always a frontal light... think about it, if you have to set your on-camera flash to the lowest power to get the effect you're after, what's the point of having a flash on the camera at all? At that point you understand how the ST-E2 makes a lot of sense as you're able to use that 550EX as main light and then group B (eg. your 420) as fill-in or accent light. -greetings, Gerard. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
