JJC LH-JDC100 consists of a filter adapter and a hood part, and the filter adapter allows the use of 67mm lens filters or a 67mm lens cap. In this way, you can use the lens hood with a filter simultaneously. JJC LH-JDC100 Lens Hood is designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. The non-glare matte finish on the inside further prevents or limits lens flare. No vignetting will show with the hood on.
