I'm not sure if that's totally true. If it was, wouldn't the wider apertures not work? I mean when the lens is wide open, more light still does comes in, therefore at least on elements close to the aperture all the glass is being used. Like I said, I'm not sure, just thinking aloud. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
