Is it possible to put an rb67-sd rotating adaptor onto the older rb67-Pro body? I have noticed from photographs that the rb67-sd rotating adaptor has two pins whilst the pro has only one.
I have a 6x8 film back (autowind) and want to get the full 6x8 negative format. With the rb67 pro rotating adaptor I get 6x7.25 negs.
I have searched around for a direct answer to this question but no luck. Thanks.
