Breakthrough Photography X100 Aluminum Adapter Ring for 67mm Lens

Adaptor rings fit into the lens to accommodate the X100 filter holder. Once the adaptor is in place the filter holder snaps firmly to it using a smooth, quick-release, spring-loaded mechanism. The wide-angle adaptors are designed so that the filter is placed as close as possible to the front element of the camera lens and should be used to prevent vignetting with wide angle lenses.
