Have sensors really passed the resolution of lenses? NO!

There is also the "Kodak equation" which used say something like the
resolution of the system is that of the lens and that of the film
combined - it's not simply the worst of the two. I can't find the
equation offhand, it may have been: sysres = 1/(1/filmres+1/lensres)

Isn't it
MTF_{system} = MTF_{lens} * MTF_{sensor}
?

That would make sense --- MTF is 0--1, the whole system is weaker
than all (imperfect) components, the weakest component limits the
system most (and increasing the better component(s) only results
in slight improvements overall), ...
