My olympus pen ft has the shift focus.Because of the focus screen.I change it with the new slipt type.But the new one is not the original brand product.It is 1.5mm in tall.And the original one is 1mm in tall.So I have to adjust the viewfinder system to fit the new situation.But I have no idea to do that.I am the old camera fans.Can any one give me some suggestion?I have the picutre for the viewfinder system.But I cant upload here.If some one need,I'll email.
If I understand you correctly, you replaced the focusing screen with a thicker one. This has shifted the focusing surface of the screen 0.5mm out of alignment. There is no practical way you can adjust the viewfinder to work with this screen as installed. The focusing surface of the new screen MUST be in the same position as the original one. The original screen was positioned so that its focusing surface was the same distance from the lens mounting flange as the film. With the new screen, these distances are not the same.
