Identifying S2 Prism and how to attach

I picked up a Bronica prism for the S2/S2a series and I'm having trouble

identifying which one it is. It has two screws on the sides of the mount holding

two small pieces of metal which prevent it from going into the mount directly.

In my searches for info, I saw mention of it possibly being attached on top of

the waist-level finder, but can't figure out how to do that.

I've looked through the forum here and the Bronica medium format site without

finding any specific answers. Anybody have one for me?

Thanks in advance,

James

You must remove the standard focusing hood before you can mount the prism. If it's a 90 deg prism it's the A model if it's bigger and heavy with a 45 deg angle it's the C prism

Using focusing hood

The focusing hood of the Zenza Bronica Model S2 can easily be removed and inserted. It is possible to use the prism finder for eye-level focusing or the outdoors magnifying hood which is adjustable for individual eyes. [n.b., using a +/- diopter range on magnifier]

1 - Press upward the focusing hood retaining lock on the front of the camera body name plate and remove.

2 - When inserting the focusing hood match the two tips on the back side of the focusing hood frame and the two holes on the back side of the focusing hood.

Press down and lock the front side of the focusing hood.

This is the web site you need to see to get as much info on your older Bronica.
