Mamiya 645 prisms for Super / Pro . . . ?

[aoluain]

Hi All,

I am tearing my hair out [whats left of it ] trying to find out
how each of the 3 possible prisms for the super/pro cameras do.

To my knowledge there are 3 . . .

AE prism fe401
prism fp401 [non metered]
and the prism n [non metered] not an angle finder but kind of looks like one ?

what does each one offer apart from metering or not?
Is there a limitation in other aspects like shutter speed or something.

Hope these querstions are not too silly :confused:

Hi aoluain:

The Super was designed to take the following finders: Waist Level Finder N, Prism Finder N and AE Prism Finder N.

As indicated in the manual for the camera, the Pro was designed to take the following finders: Waist Level Finder N, Prism Finder FP401 and AE Prism Finder FE401, but viewfinders for the M645 Super can be used with it.

If I recall correctly, there is a problem if you try to use an AE Prism Finder FE401 on the Super.

There is also another finder that one finds from time to time on the Pro - it is the SV AE Reflex Finder or SVX non-metering Reflex Finder. These finders have the variable diopter, and again, If I recall correctly, there is a problem if you try to use an SV AE Reflex Finder on the Super.

I have used both the metering and non-metering N prism finders on both the Pro and the Super, without problem.

thanks Matt,

Hmm I was looking at buying one of those svx type finders they seem to be cheap enough,
Might have to rethink if its going to cause potential problems.

again, thanks for the info.

Hello, it's my first post, but I've been reading You a lot

SVX finders are not prism. It is mirror design with dim and deformed image. Get any other prism even without mettering and You will be happy.

Best regards
