Bronica ETRSi AE-II eye correction lens screw

Hi,

I have lost the small screw that holds the diopter correction lens in place. Does anyone know where I can get one from, I have tried e-bay and UK medium format camera shops to no avail, or alternatively, the thread size for the screw so I can make something up.

On a similar subject, for me I need a correction of -2.2 diopter to be precise, I have a -1.5 diopter fitted which does not really allow ideal focusing and tried a -2.5 which is worse. is there such a thing as a -2.0 diopter correction lens?

thanks for taking to time to read this.



regards

Have you tried simply to look in the stacks of drawers stocked with metric machine screws found even in the neighborhood hardware store? Bring along the item that the screw fits into, to ensure right diameter and thread pitch.
