I buy second hand cameras and they break. I continue using them until I can use them no more. 

I had a Hasselblad with a non-synching lens, a light-leaking back and a shutter that fired intermittently. 

A Rollei SLX had a slippy back. I held it on with a piece of string. It worked - some of the time. 

These are the pictures from those cameras.They're Broken Camera Pictures.
