This is very true. I once saw a test between a Rollieflex, Hasselblad 500cm, Mamiya R67 and I believe another camera all shot hand held. The Rollieflex easily came out on top in the vibration department. The surprise was that the RZ67 came in second. I guess because it is so massive and heavy.
If you hold an RB/RZ with your arms hanging down (or supported by a strap), vibration is negligent down to 1/8. The only issue comes from holding it up to your eye, in which case your arms start to shake like you just had 3 cups of coffee.

I used to own an RZ. I had both waist level and a metered eye finder. I hated the eye finder. With the strap, waist level finder and grip it wasn't bad at all. I used it for portraiture and shot most everything on a tripod. RZ'z are great portrait cameras!
Weird and huge. It will certainly attract curious people on the street. Then, when you agree to take their picture and promise to send them the 3D photo, every one of the five coupled leaf shutters fall apart.
