Thanks for the great info, I'll see if any photo buffs around here want the enlarging lens or the Sakar stuff (ha). The polaroid lens has a shutter built into it which I just discovered you can only activate with a cable release...which I think is pretty cool.

If the value of the pin back is lost by changing it out, I'll probably end up selling it to someone who wants a pin backed camera. You can actually still use the viewfinder, but as you can see it does not make for comfortable picture taking
