LEE Filters White Lens Caps
The LEE Lens Caps come in packs of 3. They allow you to leave the adapter ring attached at all times while keeping the front element clean and safe. The lens caps are made of white polypropylene and, when attached, can be used to white balance a digital SLR, or as a makeshift incident lightmeter on any camera. They can also be written on to identify lenses in the camera bag.
