Kurt,
A photographer friend of mine who shoots Hassy and flies all over the world working for them at trade shows, etc. shoots the same "type" images that you posted and he makes a nice income from selling those as stock to Getty. I don't have the "eye" to do this well, perhaps you do (or don't) but the fact is that MF gear is used, productively and profitably, for this type of shooting.
