There is a website in the US (possibly other places) called Freecycle.
There are Freecycle's for a lot of cities. You can get free cameras and film stuff there (tons of other stuff too).
Read and follow the rules when you visit this site.

I was gifted several cameras from there. Mostly point and shoots.
I got a Yashica Electro-X ITS and a couple of screw-mount lenses for it on there. Works perfect.
