What size is the focusing screen shim?

striker_ · 09-06-2013, 10:44 AM

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?

They say it's 0.35mm.

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

Well, it's only half a lens. The good half.

haha now I see its a half lens attached to a vivitar converter. :P

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