Welcome Tim :)
I've wondered if lenses can resolve enough to give either an advantage. Suppose you have a 200 megapixel camera and the best lens can only resolve 60 megapixels. When will digital reach the limits of lens resolution, and will it be that much higher than film (which I believe may have already reached this point). I recall someone saying an 8x10 negative has well over 2 billion "pixels", I think that will keep me going for a while, and no need to worry about data integrity of 5gig image files.
