Hi there. I just recently discovered Polaroid 665, however it is sadly being discontinued. The format isn't 6x7 or 6x6, so what size negative holder do you use to print the negative that it creates?
I have a negative carrier especially for this for my Omega D2V, but you can just use a glass 4x5 carrier and make a mask out of some rubylith if you don't want the borders. I use the glass carrier because of the flatness issue.
