Hi Phil,
thanks.
to 1: Not a single shot at 1/30 of a series of 20 pictures got blurred. I scanned the cover photo at 3200dpi with a Flextight X5. Gorgeous quality at 100%. Yes, the 67II seems slightly less prone to shutter shake. I can shoot it at 1/30 or 1/45 with any lens, most results turn out great.
to 2: yeah, you are right there: those grandpas of rock didn't move that much.
to 3: I could not have shot that picture with a 165 or 200mm.
I did use a 100mm Macro on the second series, though. Again no probs.
However, I do agree with most of what you say. As I said: I'd love to shoot my 645D at 1/250 or 1/500 sync.
