This was my father's and he used it up until 1996 when my daughter was born. He passed away a month later and it has been in a storage tote since then. I honestly know nothing about cameras however I know he was real careful with it. As a little boy I was strictly forbidden to touch any of his cameras, light meters, tri pods and such. This was in a sealed tote and kept indoors. Nothing is seized up but the lens cover has gone missing.
