>Herb,
    Resolution test done with real film indicate the performance of the
film
and lens combination. The actual resolution of the lens is much higher than
indicated in a simple test.
    The relation ship is
1/final resolution = 1/film resolution + 1/lens resolution.

by this, a smaller imaging element is better than a larger one at a fixed
number of pixels since there are more pixels per mm of linear length.
