Mamiya C3, C30 - Split image or microprism viewfinder screen

[psmithp]

Does anybody know whether Mamiya made these? Or if somebody else makes them?
I find the standard very difficult to work with, especially when there is not much light.

Only the C330/C330f, and C330s were designed with user replaceable screens. The other models would need the screen mount dismantled to take a third party item, and you would have to verify the focus.

Mamiya made both 4 degree and 6 degree split image. The 6 degree version is optimised for wide angle lenses. There was also a microprism center spot version, and a rare combined split/microprism.

The C330 and C330f share a screen design. The C330s has a different design.
