    Sinar P2 Bright screen w/ Fresenl replaced with OEM Sinar GG

    My P2 came with a BrightScreen glass and a fresnel. I wanted to try an OEM Sinar GG because I like the grid pattern better. The BrightScreen glass is clear with a fresnel installed. The OEM Sinar GG is frosted. So, if I want to use the Sinar GG do I keep or remove the fresnel and if removed, won't I need to shim the Sinar GG?

    Thanks,

    The fresnel on Sinar cameras is installed on top of the focusing screen.

    So the brightscreen gg has the fresnel on the lens side and the gg on the eyeball side, so you’re saying that if I use the Sinar oem GG I should have the GG on the lens side and the fresnel on the eyeball side?

    Yes. The OEM fresnel can be installed and removed in a second. It has hooks that are latched on to the back.
    There is no way to install the OEM items any other way.

    The fresnel I have must not be OEM, it has no hooks. I put the fresnel towards me, then OEM GG on the lens side, does not seem right to me. Just seem like I'm looking at frosted glass.

    Is your Brightscreen a sandwich of a focusing screen and fresnel? If you're using an OEM GG, you need an OEM fresnel.

    It’s two separate pieces.

    On re-reading this statement, I'm confused. The OEM GG is installed first in its designated location under the clips and the screws tightened. Remember, the ground side is the image forming plane and faces the lens. The fresnel is placed on top, with the grooves towards the lens.

    Here are some pictures,first the back.
    The way it came to me was with the fresnel on the left installed first the the Brightscreen GG
    Now with the OEM GG which is on the left and looks slightly frosted.
    So I’m not sure if that Fresnel will work with the OEM GG? If so put the OEM GG in first, the Fresnel on top them, which I tried but it didn’t seem right.

    Ok so after more testing, the OEM GG does not work with the fresnel I have, but the BrightScreen does. I’ll try to use the oem GG without a fresnel and see if the actual images are in focus. I don’t have any shims, it’s just sitting on the back and the clips on top.
