It's more about the mirror slap, even at 1/30 it's pretty hard to get a clear image even with some cheap tripods some mirrors just slap hard, heck the Mamiya RZ67's amd Hassleblad mirrors are so heavy at 1/60 you have to be careful.

I am pretty steady and HAVE hand held long lenses, heck I can hand hold my 70-200 lens at 1/30 without IS but that's because the dampener on the new 5D is AMAZING not so with older SLR's

Medium format SLRs have much bigger mirrors thus more effect from the slap. I will shoot with my 35mm SLRs at speeds I wouldn't attempt with my Mamiya 645. 6x6 of course is another step up and yet another to 6x7.

My comment about doing well at 1/30th was referring to 35mm.
