Interesting thread I mainly use 35mm and have bulk loaders with both Delta 100 and Pan-F, the grain signature of these two is similar, the contrast range similar, so I use the Delta when I need 100 ISO the Pan-F when I can make do with 25 ISO.
Perhaps you can provide a photo to support the claim?
No sorry, currently I can't, because my scanner is broken (and honestly I don't miss it at all, real optical prints from my darkroom are so much better).
Furthermore it is only a 4000ppi scanner. Not good enough at all to resolve the full detail of films like Pan F+, Delta 100, TMX, RPX 25 and so on. Did such tests in the past:
Pan F+, Delta 100, TMX resolve in the 120 - 140 lp/mm range already at medium object contrast.
My Coolscan V resolved only 55-60 lp/mm of that, so less than half!
But with my APO enlarging lens I've got almost the full resolution of the films.
Scanning is absolutely inferior to optical prints, and not a good method to evaluate film performance.
