I need a TTL prism for my Mamiya M645 1000S body.

I am confusing about the TTL prism of Mamiya 645.

There are PDS, CDS prism for Mamiya M645.

What is the different between them ?

And can the "Super power driver N" be used in my Mamiya 1000S body ?

Thanks for any help !!!

The PDS meter prism is special designed for M645 1000S.

And it can measure at the top shutter speed 1/1000 Sec. of M645 1000S.

Hope this help !

Please check the focuse screen.

Maybe there is something wrong with it, and make some error when you are focusing.
