Does anyone know of a commercially available converter from the
flashbar contacts to a standard PC cord, so the camera could be used
with studio lighting? I am talking about the OneStep model that takes
SX70 and is white with the green and red stripes in the middle. Thanks
in advance.

Paramount is likely you're best bet. They'll make almost anything.

Thanks Nick. That was a good idea, but unfortunately they don't have
Polaroid tips listed as a custom option. I will email them anyway to
see if they can put something together.

did they make an electronic flash for that camera or was it just
flashbulbs?

if they didn't you will need to deal with the flash sync difference
between a flash bulb and electronic flash. that is going to be a little
trickier than finding just a cable...

I think that's why it's so hard to find. I've seen pics of the adapter
online, but no one has any for sale. The SX-70/OneStep/Pronto cameras
use either flash bars or a Polatronic flash (aftermarket electronic
flashes also available). I just bought a Polatronic on ebay, and can
use that to slave my Lumedynes, but the adapter would be simpler.

I think you'll need more that just a flash cord. Since you are going from a
flash bulb to an electronic flash you'll need a delay, else the electronic
flash will fire while the shutter is still opening and get underexposure.
Google it someone has made something similar, maybe even Polaroid.

Try to get a hold of a flashbar and try to wire it up. There were after market electronic flash units made for the SX-70 Cameras.

I'm curious why would you want to do this?
Not just for Flash but why use a One-Step at all?
