I recently bought this video camera (Keystone Americana K-773) from an antique store but I can't seem to find much of anything about it online. (For the record, I know very little about 8mm film so please bear with me.) Most of the controls seem pretty straightforward but I do have a few questions that maybe (hopefully!) someone will have the answers to. (Sorry if any of these questions have been asked before in immediately obvious places.) 1. Does the camera take 8mm film or Super 8mm film? (I don't really know what the difference is.) 2. On the right side of the camera in front of the winding crank there's a horizontal bar that can be moved up or down, kind of like a lever. What is this? 3. On the front of the camera, next to the viewfinder, there's some text ("Electric Eye Turret") and underneath it says "No filter" and then "Type A" and you can switch between the two. I'm not sure what "Type A" means. 4. Is there any way to manual focus with this camera? Thanks in advance for any information!
