Personally, I don't shoot any slower than 1/60th of a second with any camera hand held. Shooting hand held at slow speeds is not recommended for the Hasselblad. I believe the mirror plays a lot into this. I saw a test once between a Rollieflex TLR, Hasselblad 500cm and a Mamiiya RZ67. Of course the Rollieflex won but what was surprising was that the RZ came in second. The testers figured the added bulk and weight dampened the mirror a bit.
