Moving ShutterBands on and off the "gutter"
The groove where the lens and camera body meet is like a gutter.
This gutter collects lint, dust and debris from your camera bag, hands and the environment.
When you remove a lens, that junk is dislodged - at risk of falling into the camera body through the lens mount opening.
Your camera's shutter and sensor may be exposed to this falling debris.
ShutterBands provide an extra layer of defense by covering the gutter so that foreign materials cannot collect there. Help keep your sensor dust-free with ShutterBands.
Many lenses allow the ShutterBand to be stored on the lens barrel. We recommend installing a ShutterBand on each lens if possible, so it's ready to use.
