Google Groups rec. photo darkroom
Back in the day (don't ask me what day that was) Lica;
Nikon; Contax;
Canon; Olympus; & other 35mm manufactures sold
re-loadable
cassettes
that would only operate w/ their cameras. Many if not
all
cassettes,
once installed in the camera, would open to allow the
film to be
advanced w/o drawing it through a scratchy felt light
trap. Do any of
these companies cameras still operate these dedicated
cassettes? I.E.
will a Nikon f5 work w/ a Nikon dedicated reusable
cassette. If not,
does any one know which models discontinued this
feature?
I've Googled
my eyeballs out and can find no info. relating to
specifically if any
mfrs still makes a camera that interfaces w/ these
dedicated
cassettes. In fact I keep getting the same Wikipedia &
other stories
over & over again. They retell the 1st 35mm film &
Lica's
contribution
to advance the use of 35mm, over & over again & mention
Kalt & other
non dedicated cassettes that drag the film through a
felt
passage
available today.
Any info about this greatly appreciated, Particularity;y
about Nikon &
Olympus OMs.
Thank you, JD

I have some ancient Nikon cassettes for use in my F-1.
You are right that these cassettes were dedicated to
particular cameras although I believe that some cameras
take
Leica type cassettes and some Contax type, perhaps there
were others. I mostly use no-name reloadable cassettes
from
Freestyle. I've had some for years and have never had
problems from scratching from the velour gate. I do take
the
precaution of cleaning cassettes carefully before using
them. I don't know if any of the dedicated cassettes are
still made, probably you will have to find them on the
used
market.
For those not familiar with these they use a shutter
arrangement instead of a felt or velour film gate. The
shutter is opened and closed by a lever in the camera.
While
this method eliminates the film touching any part of the
cassette when feeding or rewinding but, if not carefully
loaded, they can jam and I have had that problem.

Oh BTW What are the exact precautions you take? How do you
clean the felt light trap?
Thanks again Richard

Mostly just with canned air. However, you can also use
sticky tape, like Scotch tape or masking tape to pull grit
off the felt. The problem is that it can also pull some
fibers off the cloth. I Keep the cassettes in a plastic bag
between uses and in cans when loaded. That also helps
because they get a minimum exposure to grit. BTW, I still
have a lot of Kodak cassettes from before they began to
swage the ends on.
Having said this cassettes have a limited life because
they will eventually begin to leak light or scratch the
film.
My Nikon cassettes all came without the spools but I
found conventional plastic spools work OK. I suspect the
originals may have had some sort of fastening on them for
the end of the film, I just use black masking tape.
