Mamiya AFd III + DM22

Postby davidtannfors » Sat May 16, 2015 1:52 pm


I've upgraded my back from a DM22 to a P30+ for my 645DF body.
I got a AFd III body along with the P30+ back and I thought I would sell the AFd III + DM22 forward but I cant get the body to fire with that back, it works good with the P30+.

AF works and the back says ready and all but when doing a full shutter press it focuses and then nothing more.

Is there a setting that needs to be altered? Been reading the manual front to back but cant figure it out (weird since it works with the P30+). The DM22 works like a sharm on the 645DF body.

Is it a firmware issue with the body? I've got the latest firmware on the DM22 from 2011.

Odd since DM22 was kitted with the AFd back in the day it seems.

Most typical issue is that the DM22 does not know it is on a AFDIII.
If it doesn't, then it does not know how to communicate.
This is something you setup in the Setup menu.

Phase One backs are different, they "just works" ;-)
