Although improvements in lens and film quality has changed what can
be done in the smaller formats, those same improvements have also made
their way to the larger formats. Just about all modern film types are
available in larger formats. New lenses (like the Super Angulon XL)
use aspherical elements. And the larger formats retain their ability
to render better tonal gradations and provide higher resolution at the
final magnification.
In the end you just can't beat square millimeters.
