This is comparable to the resolution of silver-based film of reasonable
sensitivity.

As mentioned here many times the E-1 lenses are design for future, not only
aim at current 5MP CCD. BTW, the anit-alias filter in the E-1 will take care
of lenses with too high resolution problem. If you believe the MTF posted by
Olympus they are much better than most 35mm format lenses.
