Canon FTB shutter fires when advancing film

Mid roll started to shoot while advancing to next frame. Shutter wouldn’t cock to press shutter button, it just fired itself.
Worked fine on last roll.

Any ideas why this is / where to look to troubleshoot? Was hoping to take this overseas in a few days!

Thanks

May be the opening curtain latch is not catching.

Hmm something like that could definitely be it. Seems like it could be a deep in the camera fix though. I have cycled the shutter about 40 times now at the problem hasn’t come back…
It did it about 10 frames in a row and now nothing.
Tyne camera is on that Borderline of “can I trust this camera”

I popped off the bottom plate to find a literal screw loose - and a component that trips the shutter had shifted. Put the screw back, adjusted the loose part and all *seems* good now.

Is it possible an attached N-FD 35mm-105 lens could be causing strain on the stop down lever / shutter and problems deeper in the camera?
I can't be sure but the camera worked fine until the new lens and now it's having some troubles internally.

Maybe just cooincidence and the camera was going to act up anyway... food for thought. Anyone experience a lens causing camera issues with shutter / aperture levers?

It's a roughly 60 year old camera; I would guess it's probably just a coincidence.

If you really intend to keep shooting with the camera, a CLA would be a good investment. It would set your mind at ease about trusting the camera and extend the life of the camera itself. The FTB is an excellent mechanical SLR, but like all machines, they must eventually be serviced to continue to operate properly.

Sure a replacement body would be less expensive, but then you still have the specter of the unknown mechanical state of the camera lurking in the back of your mind.

I have learned over the years that I really do not "save money" by avoiding service fees; I just pile-up camera bodies that eventually fail due to no service (along with the wasted film and missed images) and am generally wary the camera will fail on the next shoot.

I agree with Kino. With what film costs today, it's nice to have a camera which works properly.
