Interesting failure with IIIf

[Toni Nikkanen]

I've had an interesting failure with my Leica IIIf. I think I was a bit sloppy loading the film, since frames 0 and 1 overlap. Well I don't care about that, and frames 2, 3, 4 are just fine. Then frame 5 is totally messed up as you can see in the image below. Frames 6-37 are just perfect with absolutely even spacing and no problems whatsoever. Concentrating on frame 5, what could possibly have happened? As I remember it, I changed lenses (Summitar to 28mm Canon) after exposing frame 4. But how could that have caused such a huge light leak, if that's what it is?
And... the sun was behind me as I took this photo, and the camera was in a Zhou half-case.

Really can't tell, sorry.

But if you get rid of the lettering you can claim it to be a shot of a UFO and a mysterious wall of alien fog! 😀

That looks really, really strange... Try e-mailing a repairperson like Youxin Ye the image and asking his opinion on the matter.

Toni, I had a similar problem changing lenses. With the lens off the aperture is huge 😀. Light splashes around everywhere and I noticed the curtain was getting a bit thin, too.
Only advice I can offer is to find the shadiest place you can when changing lenses.

looks like light coming in from the front to me, past the shutter, if it was getting in anywhere else it would extend to the shots either side
