I don't know electronics, but if I understand correctly from my brother's explanation, they are fine. As long as the circuit is designed to handle the voltage (1.2 volts per cell) the capacity has no bearing. (1200, 1600, 1800, doesn't matter.) I have been using 1600ma NiMH's in my 550EX for months with no problems whatsoever. I had called Canon also, and was told they are "no problem". -- if everything is going right....you've missed something. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
