Sears used to sell some liquid flux in a pink bottle that might help --
if you can find some, try this:
Heat the contact, then dip the end you need to solder into the liquid
flux. Then try soldering a jumper wire to it. If that works, use a
sleeve and solder the jumper to the camera. A spot of glue on the wire,
cover the solder joint with the sleeve, and you're done. That's how we
solder a lead to the battery contact of an OM-1/1n when it corrodes
off....
