Hi Alex > F3 and 35mm f1.4 Nikkor - please help If your camera is exposing correctly, then the automatic aperture indexing is working (AI). As you can not see the apeture in the viewfinder, then the lens was changed some time ago to fit your F3 and other cameras who need the AI. You can have the Aperture ring changed, but I don't know weather this is done in Greece (right). There was a posting recently about someone who changes the Aperture rings in the US. Try to dig in the archive.
