Imacon I-adapter Issue
« on: May 18, 2009, 03:08:08 pm »

Hi,

I recently bought an I-adapter from ebay for my mamiya 645 Pro, this was before getting the digital back as I hadn't found one yet but knew I needed one.
I then found a 132c but the adapter doesn't seem ti fit making it look like the adapter is for an older version of this back.

Does anyone know if Imacon changed the adapter for the newer backs? I can't find any info on the web.

Thanks

Jason

Imacon I-adapter Issue

when imacon had only the 16mp back the adapters were made with that size sensor in mind
you may have one of the early adapters..
I had one and wanted to use it with the then new 22mp back ..looking closely it
was an almost fit, the opening for the sensor was just not big enough ..so I took a file out and enlarged the opening just a bit to allow fitting..
this was not their suggestion but it worked fine for me.  
I am not certain this is the case with yours but check it out.. sure beats buying a separate one.

The earlier 16mp Imacon DB had a square format, roughly 37mm x 37mm, and this is probably the one you bought.  The later version has 1.1x magnification and has a CCD sensor size of approximately 37mm x 49mm.  This newer one fits both the 22mp and 39mm backs.

just to clarify.. my rollei 6000 i-adapter for the first imacon ixpress 96 had a 60mmx60mm opening to allow for the 16mp sensor..when they came out with the 22mp sensor it was just shy of fitting my adapter.. I had to shave off about .20mm off one dimension to fit the 22mp. a very small amount. I just measured it and it is still about 60x60mm.. I am assumming the mamyia645 adapter is the same..but I doubt there are any earlier adapters than mine.
