Change CF-22 digital back adapter from Mamiya AFD to Hasselblad 500C


First of all, it did not work well today,

so I will come back for 2nd round try soon after searching necessary information.

(Right) Instruction manual, Torque drive, Sync cable









This is Mamiya AFD adapter. Note electronic contacts upper side.












Mamiya adapter removed.

I got stuck at first since the screw driver not fit at all. Then remember I have another driver (red one) and found it fits perfect.

How come they use different screws for the same digital back?












CF-22 without adapter.

Can see electronics contacts surrounded all corners…. not sure them are all used but could be

if consider Imacon / Hasselblad support many other medium format camera which not supported by Leaf, Phase One
























Switched to Hasselblad V adapter.




























But, the back does not capture the image with Sync cable.

It just stay calm as if no signal came in.


During test, 1 time it capture the image suddenly (it reminds me previous Leaf Valeo set up which took 3 month to figure out…)

So I think there is poor contact point somewhere instead of fundamental issue.


(1) Poor X sync from the lens –> I have SWC/M so tested with this lens too : Same symptom  –> not this problem

(2) Cable itself bad  –> I tried 2 cables & they were working find with Leaf back –> not this problem

(3) Adapter’s sync port issue –> may be or may be not :

If I connect to Digital back directly instead through adapter, I could figure out whether it is OK or NOT.

But before this try, I like to find out more information. There are 2 ports, one in red and the other in green. Which one should I?

(4) Software setting –> there are different settings, ELX, ELD, CW & generic…etc

since I tried all of them, I don’t think it is the cause of the problem. But there may be something I did not figure out yet…



Anyway, I tentatively conclude it is contact issue because of 1 time successful image capturing.

Probably attaching adapter is not adequate…


I switch back to Mamiya AFD now, and will come back this job soon again.
