Doing some camera repair or maintenance? Light leaks can ruin your photos! This Pig Iron light seal foam sheet is exactly what you need to replace old, crumbly foam inside your camera. The sheet measures 200mm x 100mm (about 8\ x 4\) and is 1.5mm thick. One side has a strong self-adhesive backing, so you can easily cut it to size and stick it right into the camera's mirror box, film door channels, or other crevices. It's made from a special anti-reflective, light-absorbing material to prevent stray light from bouncing around and fogging your film or sensor. It's a universal product, compatible with all sorts of cameras: Digital SLRs, Film SLRs, Rangefinders, Medium Format, you name it. Brand new from Pig Iron in the UK, with a 1-year warranty.
