This is the "original" version of the camera body-based ronchi grating focusers made by STI. Constructed from an Olympus OM-1 body and a star diagonal with a ronchi grating insert, this unit is used to provide knife-edge focusing for your Olympus 35mm camera. Requires an eyepiece for use. I'll include full instructions on how to use. $75.
