Is that the reason that when the camera is set to Full Auto, if you focus on something dark but really far away the flash will still come up ? I find it a bit silly for a camera with otherwise sophisticated algorithms to believe it can use its tiny popup flash to light something that is 50 metres away. And a contradicting question: Can you use an external flash like the 550, have it switched on, but let the camera decide when to use it ? Or once its connected and switched on it will fire nonetheless ? * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
