Lee 105mm Front Holder Ring
The Lee 105mm Front Holder Ring enables the Lee Circular Polariser 105mm filter (not included, available separately) to be rotated independently of any other filters. Landscape photographers tend to use this set up with a square graduated filter in conjunction with a wide-angle lens, as this allows them to experiment with taking long exposures. The Lee 105mm front holder ring attaches to your holder (not included, available separately) via the four brass screws that are already in the Lee holder.
