It probably does play a part IMO, but it's very difficult to attribute
such differences with certainty as both scanners are a complex system of
optical, electronic and software components, and perhaps even different
design aims and optimisations. cf.eg. Nikon/Canon vs. Leitz lenses - I can
imagine that biting image sharpness would be a Nikon scanner
design priority, due to the market position they inhabit. Sadly I don't
see how anyone can rigorously deconstruct all this without a well equipped
lab and the sort of resources that the mfrs. had in the first place -
about all we mug punters can do is try and characterise the overall system
so we know what we're getting.
