But I do agree, Steve, that a hassie (or rb) is certainly handholdable to 1/60. If that's really what you want to prove then why not simply show shots taken handheld at 1/60? The penny thing proves nothing in this regard.
Along those lines, this shot was handheld at 1/15 or 1/20, as I recall, with a mamiya 645 afd. 1/60 is nothing.
