Irix Edge IFH-100-PRO 100mm Square Filter Holder

The Irix Edge IFH-100-PRO is the upgraded version of the IFH-100 square filter holder, designed around the problems that show up on long exposures: light leaking in behind the filters, and a polariser that has to compete for a slot with the graduated filters.

It takes the same Irix Edge 100 x 100 mm and 100 x 150 mm filters and mounts to the lens through a threaded adapter ring, sold separately. The Light Stopper accessory seals the front of the holder for heavy neutral density work. Aluminium construction throughout.
