The measurement of the foam or felt material used to prevent light from leaking into the Canon F1 camera body is a critical factor in ensuring proper exposure and image quality. Light leaks can manifest as unwanted streaks or fogging on film, particularly in bright conditions. These seals are positioned around the film door, mirror box, and other potential entry points for stray light.
Maintaining effective seals is vital for accurate metering and preserving the integrity of images captured with the Canon F1. Over time, the original sealing material can degrade, crumble, or become sticky, leading to light leaks. Replacing the old seals with correctly sized and properly installed replacements restores the camera’s ability to block extraneous light. Historically, various materials and thicknesses have been employed, with variations impacting seal effectiveness and longevity. Factors like material density and adhesive properties play a significant role.
