Subject: RE: [Leica] Light Leak in IIIc

Matthew,

 Leica IIIc are notorious for the light leaks, especially the
early ones. I had a Leica IIIc with a very same problem, also
manifested in a very similar manner, same pattern, also
my Leica had perfect curtains ...

 Actually there was a light leak bellow the film advance knob.
I would suggest that you take the Leica IIIc to a skilled
repairman and ask him to check the film advance knob if it
is light tight.

 Hope this helps.

Cheers,
Matej

Subject: [Leica] Light Leak in IIIc

I have the most baffling light leak in my "new" IIIc. I get about 10 
or 15 "leaks" per roll; most are confined to the top right of the 
negative(bottom of the camera) in the sprocket hole area, and a 
little into the negative, and looks sort of like a bent triangle (if 
that makes any sense). About five of the leaks are black lines, maybe 
a centimeter wide, running top to bottom on the negative (white in 
print). I know this has to be happening while the film is on the 
take-up spool, as the sprocket holes make nice little black squares 
between the holes behind. I have checked absolutely everything: 
shutter curtains, curtain baffles, screw holes. I even taped up the 
baseplate where the adjacent vulcanite is missing as I thought that 
light might be getting in there. I have taken the camera into a dark 
room with a bright Mag-light and checked out every concievable 
combination of shutter curtain position, film speed, etc. I have 
tried a different lens, and tried not removing the lens while loaded, 
all to no avail. This is my first Leica after two years of a Zorki 1 
(that works perfectly), so I am a little disappointed with my 
experience thus far. Any help would be greatly appreciated.
