Expired Polaroid

A friend gave me a box of expired Polaroid film that she had. I did not think the film would develop, but it did. The pictures are a bit faded as you can see, and the left corner is missing. The film was so quick to develop compared with the Impossible film I have tried, and the result are more predictable. 

PolaSonic AutoFocus 5000

Bought this Polaroid Land camera a while ago, and have been using it with Impossible SX-70 film. I find it very unpredictable to use. There are two things you can adjust, lighter or darker, and auto or manual focus. Camera uses Sonar to focus, "sounds" like a great concept, but most of the time I had to switch to manual to get anything reasonable. It is of course a possibly that my camera is broken. Since buying a box of Polaroid film is rather expensive, £17 for a box of 8 photos, I don't find this to be the second hand bargain I thought it would be.
