Which view finder is this? Mamiya m645 super

[Marc Estalella]

Hello everyone!

I would like to know which viewfinder is this on my Mamiya m645 super. I want to know if it uses spot or zone metering. I can only find other prism finder manuals...

Thanks!

That looks like an AE Finder FK402 that was sold as part of a kit with the Mamiya 645 Pro and/or Pro Tl.
Strictly speaking it isn't a pentaprism finder - it is a pentamirror finder. Which means that it is lighter than a pentaprism finder, but less bright.
Here is a link on Mike Butkus' site to a manual: https://www.butkus.org/chinon/mamiya/mamiya_645_ae_finder/mamiya_645_ae_finder.htm
If you make use of the link, please consider sending Mr. Butkus his requested donation.
You should note though the following excerpt from that manual:
1. The Finder FK402 is exclusively designed for the 645 PRO Camera and it cannot be fitted with M645SUPER Camera." (emphasis added)

Thanks! That really helped!

I have the M645 Super and the FK402 finder fits perfectly and works fine. I don't understand...

I'm not surprised it fits.
I would check whether it is metering correctly.
