The lifespan of Polaroid 600 film and cameras depends on various factors such as storage, usage, and maintenance. Typically, unopened Polaroid 600 film has a shelf life of 1 to 2 years, as indicated by the expiration date, but this can be extended by storing it in a cool, dry environment. In terms of the cameras, their longevity is influenced by usage habits and care. Mechanical parts are subject to wear and tear, but with careful use and regular maintenance, these cameras can last many years. However, because many are vintage or refurbished, the availability of replacement parts and the quality of previous repairs can also impact their lifespan. Electrical components, while generally robust, can degrade over time, especially if the camera is stored in adverse conditions like extreme temperatures or humidity. Overall, while the film has a somewhat limited shelf life, the cameras can have a considerable lifespan if well-maintained.
