What size is the focusing screen shim?

Hi.

My focus (for manual) is not exactly right. What I want is replace the shim for a smaller one. Do anyone know what size the one factory installed is?

Yeah, mine is, too, so maybe it's .40mm.

I took the glass out of the converter. It was just acting as an aperture. You can read about it here, if you want.
