The Hasselblad/Salut/Kievs use a grooved post to attach the strap. So does the Pentacon 6. Does anyone know if the post on the Pentacon 6 is the same as those on the Hasselblad/Salut/Kievs or are they different? I'm working on how to attach my straps to these cameras. I have a Salut-S I can play with. I want to accomodate the Pentacon 6 too.
