This is a replacement kit for the Canon Demi's Light Seals foam (backdoor gasket sponge).
When the original light seals become old, the camera can experience light leaks and backdoor rattling. By replacing them with new light seals, you will not have to worry about these problems anymore.
The light seals foam is self-adhesive and precisely cut to match the rear door ditch's shape.
This kit includes 2 sets of foam. Installing this kit is relatively easy. If you are not confident, you can use one set for practice, ensuring a perfect installation on your second try.
This kit fits the original DEMI (first version). It does NOT fit the Demi S, E, EE17, or EE28.
This seal kit covers the green halftone portions shown below. It seals light from the outside perfectly.
