Hi Konstantinos, Have you tried opening the film door an setting the camera to Manual mode and setting the lens to stop down to say f/22 on Bulb and looked through the back to see if the diaphragm closes down? Try it at different apertures to see if it is working at some settings and not at others. If it doesn't not close down when viewed this way the lens is bad. If the lens does stop down at all settings the preview switch or logic in the camera body has failed.
