    Mamiya RB prism - difference?

    I have a Mamiya RB-SD. Can someone tell me what the differences are between the old style prism and model-2? I know model-2 can work with both RB and RZ but that's not one of my concerns. I also know older types are heavy.

    Are there any difference in usability or anything else??

    Someone might be able to confirm, but I believe that the model-2 prism purports to be brighter.

    (FWIW, I just bought and returned a model-2 prism from KEH. It added significant bulk to the camera and was, in my opinion, harder to use to obtain focus than the normal WLF.)

    I have a model 2 Prism and the metered prism. The model 2 prism is made for the RB and can be used on an RZ. The metered prism is not coupled to the camera and if I remember correctly, it runs off of the camera battery. Both are big chunks of glass.

    No one had both at one point to compare??

    I'm actually not that interested in metered prism but thanks for the info. RB doesn't have a battery though.

    I've done some comparisons with my hand held Minolta spot meter and the meter is OK. It's just takes an average reading. May or may not work if you're persnickety about your readings.

    Other than the metering part, is one better than the other??? Which do you prefer?

    I prefer the newer one with the meter. I don't know if it's the age of the prism of the model 2, but the prism glass looks yellowish. Maybe another APUGer can explain. Both are cheap on Ebay. You can buy them for $100 or less.
