Take a look at this:

Interesting that it uses a lens in shutter and has no focal plane shutter. |

Ouch.

How on earth does it work with an in-lens shutter? Someone messed about with leaf shutter SLR's in the 50's and found that the mechanism is way too complex and unreliable. The shutter must be open initially, then when you fire 1) close shutter, 2) move mirror, 3) trip shutter on normal speed. I'm assuming that they didn't implement mirror return and shutter re-open!
Personally I think I should strip the leather off my Graflex, varnish it, and offer it for $1800. [Just kidding folks!!!] |

Actually I don't think it would be real hard to do. I have a Polaroid MP-3 camera body that I bought mostly for all the accessories it had with it. The Copal shutters that were made for Polaroid have the press to focus done with a cable release, and it opens both the iris, and the shutter (I don't know if a normal Copal does this, I've never had one). On the MP-3 there's a button that lets you slide between a film back, and a focusing screen, and when you release it the shutter automatically closes / stops down to the selected f stop.
Using a shutter similiar to this it would be fairly easy to have it release the shutter while it's raising up the mirror. I think you could also have the releasing of the mirror also activate a second cable release to fire the press type shutter.
Keep in mind that what I'm talking about is pure theory, I've never seen the Freedom camera, so I have no idea how they're actually doing this.
