How likely is the pressure etc of > plac ment of something like this to causing damage? There are no known 'dimple' problems with EOS cameras that I know of, the EOS-1 is definately fine. More about this, for several brands/cameras, see: http://www.a1.nl/phomepag/markerink/mainpage.htm Data-back (pepared/cutout!) pressure plates are a much more likely candidate for this tape-trick though. > 3) If you see a small stain on the plate should it be cleaned > or wiped off, and if so how and how delicately?? Anything that is safe for a lens surface is also safe for a pressure plate....;)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand <[EMAIL PROTECTED]> [note: 'a-one' & 'en-el'!] * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
