Description
This filter holder is able to hold up to two 100mm wide fitlers (like Lee, Cokin, Nisi, Haida etc.). The holder may be rotated and filters (eg. graduate gray) may be shifted. It isn't vignetting, when the lens is defished. If the lens is used as a regular fisheye lens, the filters are vignetting.
The holder consists of a mounting ring, a filter receptace and 2 screws.It comes as a single printed item and components need to be separated (spriues cut off with a sharp knife) and assembled in the intended position.
