The Motormatic is one mean machine. It actually does some pretty cool stuff for a camera of it’s vintage (1960 - 62). Kodak must have had a fetish for these clock mechanism motor drives. I’ve got an Instamatic that uses a two foot long metal tab which pulls out to charge the motor drive. The Motormatic has a big knob on the bottom. You turn it, and it’s just like winding a clock. Then, as you release the shutter the motor drive hums, advancing the film to the next exposure. The camera is big ( 3 3/4" tall and about 4 3/4" wide) and heavy. There are five shutter settings. Flash, 40, 80, 125 and 250. What? No "b". You set the shutter speed and the camera automatically sets the lens aperture, which ranges from f2.8 - f32 and is indicated by a needle on top of the lens assembly. You can set the f stops manually by sliding a knob next to the viewfinder and turning a dial below it. I didn’t figure this out until after I’d put a roll of film through it. The dial around the lens has a flash setting and a daylight setting. During focusing of the lens, stops can be felt. These stops cause the indicator in the viewfinder to change from "close" to "group" to "scene". I know! This ain’t no amercher camera! I got mine for four bucks after a snowshoe trip that didn’t pan out. I put a roll of film, which I’d found on the floor at some event, through it. The film was called Turo or Tura, I forget now. But it was 400 speed black and white and I guessed on the development. Turned out not too bad, if I may say so myself.
