Canon FT QL Frame Overlap Issue

My "new" Canon FT QL has a problem w/ the film spacing. On one of the frames toward the end it didn't advance all the way and I had a half frame double exposure. All the rest of the negs came out fine. Years ago I had another FT QL and it did the same thing now and then. Any ideas? I was guessing that it might have something to do w/ the Quick Load mechanism but don't see how, as it happened around frame 17 or 18.

If you buy a camera that's more than forty years old and probably never serviced and need a reliable working tool that functions correctly you need to factor in the price of a service.

Thanks ben. And if I go out in the rain w/o an umbrella I'll get wet. I'll write both things down so that I don't forget. We need one of those buzzers that they have on Jeopardy.

There is a chance that you pressed the rewind button on the bottom of the camera. This would have prevented the sprocket wheel from feeding film. Maybe that, in conjunction with not being able to fully advance film since you were at the end of the roll. Pressing this button would have allowed the cocking iteration of the shutter to be complete.

Do this: without film in the camera, open the back and advance 'film' and fire the shutter several times. Each time, hold your thumb lightly on that sprocket wheel. Count the sprockets that pass by with each advance. There should always be eight for a full frame to be fed. - David Lyga

The FT QL sometimes needs lubrication or things will tighten up before you get to the end of the roll. Hi David.
