Focus screen sizes

[Peter_Jones]

Does anyone know the dimensions of focussing screens for the Canon EOS1 (35mm) ?

just wondering if one can be adapted to OM cameras via use of a dremmil 😉

Just get a Beatie or series 2 olympus screen. It's not worth it.

From my experience EOS screens tend to be long enough (i.e. the longer side of 35mm frame), but not wide enough. I'm guessing but they might be like 35 x 20 mm (really just guessing, but notice the ratio). OM screens are about 36 x 25-26 (i.e. when I place it across film rails, it barely fits between the outer rails, when I put it along the rails, it's wider than the film gate.)

I'd spotted a Beattie EOS screen, thought it might have been able to fit/be fitted 🙄 ah well.
