Mamiya ZD handheld vs. tripod and mirror lockup

For a while I was thinking the Mamiya is a "tripod only" medium format camera only. As with any other cameras it depends mainly from your lens and shutter speed. So I tried my hands on one subject with different setup and the same settings.
Mamiya AFD II with ZF Back
80mm lens @ F8 and 1/200s
1. With tripod and mirror lockup
2. With tripod
3. Completely handheld only
Result: At this speed I cant recognize any difference. I compared at zoom level of 200%.
I will try with different settings going down to 1/80s.

But: Working with a tripod always ensure you have best possible results !
