Sorry, Mark. I just looked at my reply and realized it sounded
snippy. That was not my intention. All I was trying to say will all
my ineptness was that I have experience spots on the sensor filter
that required more than one going over to get it off. Some of it is
on there tight. It is stuff you don't see in an ordinary picture and
I really think that a lot of people took Oly on faith and have not
really checked their sensors. It might be there, invisible, until you
take that one shot with a lot of sky at a small f stop and you get it
in Photoshop and tweak the contrast a little.
It just does not make sense to me that dust that floats in that has
not attached itself firmly to the filter will fall when stirred up
again. It will just float around some more. Wayne's statement that he
has to clean his E-1 just confirms that.
