So, I've now been using my Phase One P40+ back and 645DF+ system for about a year now, and I still haven't managed to iron out the issues I have with accurate focusing.
A while ago I asked about the Maxwell focus screens as a fix, but because of mixed thoughts and no definitive answer, I haven't bought one. (http://www.getdpi.com/forum/medium-f...s-screens.html)
The issue comes about mainly when doing corporate headshots, where I like to shoot wide open with a very narrow DoF.
After shooting this system for about a year and doing extensive testing with other P1 back/body combinations, and having my dealer repeat my results, I've come the the conclusion that it's not user error, but an inherent part of the camera design.
Relying on the focus mask in C1P or stopping down are not viable solutions for me.
I should also mention that I wear contact lenses, and with them, my eyesight is significantly better than 20/20.
So here is what I think my options are - which may or may not help in any way.
1) Use the Mamiya focusing loupe. *Done, and does nothing for me.
2) Buy a Maxwell screen
3) Move to an RZ67 Pro IID system (for better manual focusing)
4) Move to a Hasselblad (V or H) system
5) Move to a Rollei Hy6 system
Both 4 and 5 have me buying a new back at a significant cost (I would think...after trading in my P40+).
I would consider a Leica S system, but I also shoot with the Arca Swiss Rm3di and have never seen an adaptor, so would have to move to a full view-camera system. Again, at a very high cost (and added weight).
Any other possible solutions? Any advice? Any thoughts?
