Adapting / converting a P1 digital back on a Sinar P3

[Maeda]

Hello everyone! I found a used Sinar P3 equipped with a Sinar Evolution H75 digital back. Since this back is exclusively designed for the P3, does anyone know how to make it compatible with a Phase One back? Thank you.

Really? I bought one and it didn't mount to my P3 Repro, and it left a pretty big gap between the back and the plate... That was what actually pushed me to start trying to make my own adapter plates.

Not sure if it was this one specifically, but it was a Chinese EBay one I had. Fit on a standard P3 just fine.

make sure it has space for the pins on the back. I don't even think the SINAR plate does, It only has space for the IQ3 or earlier. You could get it milled but finding someone to do it might be tricky.

I personally know someone that bought that Chinese one and it didn't fit so the QC must not be great.

I say all of this because I have been looking too. I have a P2 so use a Graflok adapter (which does have room for the IQ4 pins), but the Graflok attachment has play in it and the 4x5 standards are way too big for a 645 back.

No promises, but I did just buy a medium high end 3d scanner with the idea to finally make some progress on getting my Bronica SQ -> IQ adapter (the geometry is complex enough that I kept making mistakes measuring with calipers). Next will be a P3 -> IQ adapter, so I can use my IQ backs with my Sinar Repro or Sinar M

Cool, let me know how you go. The other issue is having it machined at a reasonable cost to a tight tolerance. It would be interesting to see if one of those online print/fab companies like PCBway could do it: you. can set your tolerance levels higher or lower (for an additional cost).

I have used xometry & a few others, so far they've done pretty well! Though setting tolerances does increase cost a lot!
