The Adapter Tube for Sony HX100 is a 67mm lens filter adapter specifically made to utilize lens filters on the Sony HX100. The adapter screws directly onto the lens barrel ring and is designed to move with the lens while zooming in and out. This provides filter coverage throughout the zoom range and prevents vignette at the wide-angle end of the zoom. It is dedicated for use with the Sony HX100 and will support any kind of 67mm filter.
