Just recently acquired a Phase One P30+ with the Mamiya mount. Shooting on an AFD III (as I still shoot film). Let me just start off by saying "Wow!". The image quality and colour rendition are phenomenal. As an amateur, I had to save up and justify for a long time before I took the plunge and I am glad I did.
The one thing that concerns me though is that I swap the Digital back for a film back fairly frequently and my P30+ did not come with a cap. I have searched various forums, ebay etc and even contacted my local dealer with no luck. Any guidance on where I can buy one would be greatly appreciated.I am located in New Zealand and being on the edge of the map often has consequences on how easily things are available

Additionally, any pointers on where I can buy acetate masks for the Mamiya AFD III for the Phase one P30+ will be appreciated as well.
