Chris ,

I advise you to hunt for Polaroid with Rodentock lenses and convert it to film.
It is the best lens I have ever seen in my life , really , that excellent.
Its like Ektar but better. I am talking about the photographs not technical side.
When there was PN 55 , there was its users at polaroid gallery and someone had been taken African peoples portraits. It was excellent. Deepest blacks and most correct portraits and photographs I have ever seen. I will try to find him and give you a link. Your jaw will drop.
Polaroid 110a , I think this was his camera.
