i have roundshot/panascope(identical) 65/70/220. if treated kindly it will work forever. had to change batteries twice. it was built in 1987, bought by me used in 1991. took it apart to the lens to show how its is working or how to replace parts. now i can replace the o-rings. only the main film-ring-flat-type is unknown yet. but seitz promised to help. for more analogue pancams go to my forum at:
