The Hard Lens Protector for Action Cam from Sony provides a way of keeping the lens protected on your Sony Action Cam when the camera is not in its housing. It helps avoid scratches as well as keep dirt and sand out of the lens, and can be removed and rinsed if it gets dirty. The protector also features a tether that allows you to tie it onto camera to help prevent it from getting dropped or lost. It works with the HDR-AS100V and HDR-AZ1 Action Cam models.
