👉 A dustcover is a type of protective cover or material used to protect a surface from dust, dirt, or other small particles. It typically consists of a hard outer layer that covers the surface and provides protection against these contaminants. In photography, dustcovers are often used for protecting lenses from dust and debris when they are moved around in the camera's viewfinder. They also serve as a protective barrier between the lens and its surrounding environment, reducing the risk of damage caused by dust or other particles.
