Thanks Yair for your quick reply! I thought by using the Pro II D there will be no cabling needed between the digital back and the camera? Will metadata be recorded for the v mount aptus and the Pro II D combo? What's the advantage for using the Pro II D vs Pro II for a v mount Aptus? Sorry for the questions I did my research in the forum but apparently the RZ Pro II D and the M mount Aptus are the most common combination so I wan't sure if everything will work for the v mount Aptus. Thanks again!
The Mamiya interface for the Pro-II D is only available for Mamiya interfaced digital backs. For any combination of Mamiya RZ Pro/Pro-II/Pro-IID you would require a sync cable unless the camera is Pro-IID and the digital back has a native 645 Mamiya interface.
