In most cases you only need to slow the focal plane shutter down to 1/8th of a second or slower, so that the entire focal plane shutter is is open during the entire duration of which the leaf shutter is open (ideally faster otherwise, what is the point). The mirror will be out of the way regardless. Things get hairy when you begin to slow down below and 1/8th of a second with the leaf shutter, which can require the mirror to be locked up.
The focal plane shutter (and mirror) are open for the longer (ie. slower) duration of time, while the leaf shutter opens for a shorter (ie. faster) duration of time within it.
By the way, the Mamiya Leaf Shutter lenses do work on an AFD/AFD II

Thanks Gem, Can you confirm that they work with out have to do the mirror lock up like many have said you have to do? I just got from New York with my AFDII but do not have a Film back nor the P30 yet so cannot try the leaf shutter lens yet. And it might be at least a week or 2 before I get my P30, So I cannot fire the AFD with out a Back apparently. I tried but the finder says NB which I imagine is NO BACK..:+}
Any body know if you can fire the AFD without a back in any way?
Anyways back to the Leaf shutter lens..
Again can you confirm this either way.
I shot for MANY years w/ the ProTL & LS lens and it was awesome and NOT with Mirror Lock-up.
So that is why I was wondering especially b/c in every post so far people have mentioned you have to Mirror Lock-up.... Which makes me wonder, Why?
SO maybe they either do not know "really" or you do have to for some mechanical reason with the newer AFDII...?
Well Thanks to anybody who can CONFIRM it either way! Or I will as soon as I get some kind of Back...:+}
Manually cranking the lens is NO biggy for me.. but Mirror lock-up and manual basically would stink and really slow the process down.
Maybe on Tripod and Hope your subject does not move ever so slightly...?
It is also Great to know that Mamiya is coming out with new LS lens.. Just hope they not in the 3-5K range...
