Alpa offers different adapter for leaf and phase one for mamiya 645 :
"ALPA adjustable back adapter MA645A (Phase One)
Adjustable with shim kit, max. +/- 3/10 mm, for digital backs only. ALPA back adapters are interchangeable and reversible: horizontal/vertical.
Please indicate wether you are using a Leaf or Phase One back as due to their different measures two ALPA adapters exist."
The new kapture group sliding back :
"This Sliding Back seamlessly integrates your Arca Swiss Rm3d to our most compact sliding back. A new feature permits the discriminating photographer to fine tune the plane of focus (if needed) precisely to a specific digital back assuring accurate lens focus at infinity."
I've also heard that the registration from back to back (same model) can vary.
Considering the new 80MP sensor, and top of the range wide angle lenses... i can imagine that tolerance value decrease again...
A friend of mine just bought a brand new P45+, and faces the problem... the answer from his dealer isn't clear for now... considering the prices of MFDB, i can't understand why all MFDB are not perfectly tune !
Anyone over here is facing such a problem ? is it typical with M645 mount ?
