Metal shutter curtain can get pinholes

[raid]

My Canon P suddenly got a hole in its metal shutter curtain. Don't think that it can only happen in cloth curtains. I got back negatives and sldies with a shiny area on each frame, and I then tested the Leica M3 and M6 first for the pinholes, but it was one of my Canon P cameras.

I just wanted you to know that it can happen to a metal shutter curtain too.

Thanks for the information. Any idea what caused the pinhole?

Can you see the hole?

Since it's unlikely that stainless steel shutter curtains are still being made, will you try to patch it up yourself, or try to get new cloth curtains?

Did you mount a f/.95 on it?

I have absouletly no idea. It looks like a full sized pinhole. As if someone poked something through the curtain

It was a sunny day today, so it was sufficient to point the camera at the window to show light coming through the pinhole at daylight.

I got a tip at RFF to use liquicdelectician's tape and apply it with a toothpick. It costs about $7 at Loewe's. I applied three times some of this black liquid on the hole. It seems to be fine now.

I don't have such a lens. It must have happend as an accident by having something poke the hole.

I am glad you found the source of the leak. I hope the tape/paint stands up for many years ...

I can always re-apply the liquid tape, Paul.

Was the curtain crinkled? I've read that the stainless steel curtains can get crinkles in them and a hole could develop.

Good to know the rubber trick works on them too. I've never had this with Nikon Titanium shutter curtains, or a Canon stainless steel curtain.

No, the curtain is without wrinkles/crinkles.
The pinhole just appeared somehow.

Gosh! 😱 Even in metal curtains? I wonder is this applies to the modern multi leafed curtains like in the Bessa R3a and the likes of the F2 with titanium curtains?

My Canon P was light tight for many years, but a hole appeared suddenly. I lost two rolls of film this way.

Brian,
The liquid electric tape [rubber] is sticky and it stays on the metal curtains. I used several very thin layers, and over several hours apart yesterday. A fix at the cost of $7 is not bad at all.
