Mamiya 645 Pro TL Prism

[Nigel Godber-ford]

Just a quick question, I have a Mamiya 645 Pro TL with a WLF on at the moment and I am contemplating getting a Prism finder for it , but I am unsure which one to buy, do I buy a plain prism or a metered prism, at the moment all my exposures are done with my Pentax spot meter which I find my exposures are spot on using this.

If you've already got a system for metering, I'd get the un-metered prism. My experience has been the that the 645 meters are not terribly accurate on a good day...

I am not that familiar with the Mamiya M645. Does the metered prism give you half shutter speeds, the way the Bronica metered prisms do?

Yup. I had a prism on mine, unmetered, and it's fine. I actually switched to a WLF a few years ago.
