At that print size? Probably pretty close to the limit. One stop open for
both would definitely get it closer to ideal, but I think that at that print
size we're at the point of diminishing returns as compared to the advantages
of the increase in DoF.
What really becomes evident in a test like this is the inherent advantage to
the film configuration due to micro-contrast.
And as to the subject of contrast vs dynamic range, you can do a lot of
balancing there by using split-grade printing. This gives you the ability
to have a ton of contrast while maintaining the gentle tonal gradients.
I maintain that a well-processed and printed Ilford PanF negative on a fiber
silver-gelatin paper will easily surpass anything remotely possible with
digital. Digital is getting much much better, but this final frontier
hasn't been crossed yet.
