Notes: Found this Ampex Vidicon 25mm f/1.4 on another treasure hunt. The other 25mm I have focuses, but you can’t change the aperture. This one, you can change the aperture, but the focusing seems to have been set to infinity by the factory. A workaround is to “focus” by not threading it all the way into the C mount adapter. Hardly a practical way to take photos, but another weapon added to the team! 🙂
