This is a Dustless Pinhole body cap for all Canon FD cameras. Specially designed for digital cameras there is a micro thin layer of glass behind the pinhole keeping any dust away from your sensitive digital sensor. We all know that small particles of dust can wreak havoc on digital pinhole photographs showing up as specs on your photos as annoying black specs. This can be used as a body cap or a pinhole lens so you can leave this on your camera when it's in your bag and simply pull out your camera and shoot photos without having to fumble for your lens.
