I had to collect most of the really important pieces of information from the web, and even that is incomplete. Not only about the various ways the camera sets aperture/exposure time under different light and in the different exposure modes, but also which metering patterns it uses. Where in the camera manuals do I find a picture of the TTL sensor's metering pattern? Where does it tell me which metering pattern the camera uses for ambient light/for flash in ETTL mode? You'd expect this to be exactly what you selected on the camera, but apparently it is not. I remember the usenet debates about the EOS 3 going to average metering for ambient light as soon as flash is on, even if spot was selected on the camera. Then with the digital bodies, the behaviour is yet different.
No, I wouldn't call this "well documented" ;-) To add a concrete question: what does the TTL metering pattern of an EOS 30/Elan 7 look like? As it probably has more than one "field", how are these fields weighted against each other? Does the selected AF point go into this calculation? (Im talking about TTL here, not E-TTL.) br/Stefan. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
