Canon Flash Quint manual:

  1. Hello everyone!

    I’m searching for original canon flash quint manual or any other supporting materials.
    Is there anyone who still owns anything regarding this flash?


  2. I don't know nothing about no Canon Flash Quint, but I do know that Butkus (the usual source) doesn't seem to have the manual, and that finding AG-1 flash bulbs these days is really tough and usually fairly expensive.

    e.g., canon flash quint - Google Search

    Here's my AG-1 flash
  3. Mike Otto, at Pacific Rim Camera, has quite a collection of obscure Canon brochures and literature. He may have something.
  4. I have a Flash Quint with the vinyl case, but I don't have the manual. However, the Flash Quint is pretty simple to use. It requires a 15 volt carbon zinc battery equivalent to an Eveready 504, and AG-1 (B&W) or AG-1B (color film) flash bulbs. The calculator dial on the rear of the flash is attached to the battery door which slides down. The clear lens cover opens upward clam shell style, allowing you to slide the bulb holder out. The flash automatically selects and fires one bulb for each exposure until there are no unfired bulbs. If you press the red test button on the back panel and the window above the button lights up, the flash is ready for the next exposure. I believe that the test light will only glow when there is at least one good flash bulb remaining. Check online vendors for the battery and the auction sites for the battery and flash bulbs.
  5. Thanks for you answer Gordon! Thing is that I actually have bulbs and batteries and all but somehow my unit shows absolutely no signs of life... I’d wish to get it fixed but so far I just couldn’t figure out where the problem is. The bulb counter got stuck and the button is not lighting up. And visually it’s all mint inside.
  6. These flash units are usually referred to as "B-C" or bulb-capacitor flash units. The battery charges the capacitor which then discharges through the camera's synchronization circuit at the time of exposure. I suspect that the electrolytic capacitor has deteriorated due to age, a common occurrence. Many B-C flash units have user replaceable capacitors. However, the Quint Flash does not. If you're mechanically inclined and willing to assume the risk, you could disassemble your flash and replace the capacitor, and clean all electrical contacts while you're at it. However, be warned that touching a charged capacitor can cause serious injury or even death. Again, the risk and responsibility is entirely yours.

    While the capacitor's ability to hold a full charge has probably diminished over the years, it may still be sufficient to trigger a flash bulb if given enough time to recharge and reform the capacitor's internal structure. The capacitor has likely discharged completely over the years and the initial recharge may take a while. Assuming you have a fresh battery, insert it and let it charge for an extended period, say overnight. Try a test exposure with an empty camera, even if the test light fails to illuminate. If a bulb fires, you may have a workable unit. However, the recharging time may be longer than practical, depending on the capacitor's condition. And, if the test light isn't working, each exposure will be a crap shoot. Good luck.
