Irix Edge IFH-100-PRO Filter Holder

The Irix Edge IFH-100-PRO Filter Holder is a universal 100mm square filter holder that adds a built-in, removable circular polarizing filter alongside its two 100mm filter slots, controlled by an integrated thumbwheel. Its lightweight aluminum construction supports two filters at once without vignetting, even on ultra-wide lenses, though a separate adapter ring is required to mount it to a specific lens.

• Fits two 100mm-wide, 2mm-thick filters plus 1.1mm-thick filter holders: Covers both standard and thin filter formats in one holder.
• Includes a removable circular polarizing filter: Position is controlled via the holder's integrated thumbwheel, usable alongside the 100mm filters.
• No vignetting on ultra-wide lenses: Lightweight aluminum construction keeps the holder compact enough to avoid corner shadowing.
• Free rotation around the optical axis: Aligns graduated filters precisely without needing to loosen the holder.
• Requires a separate adapter ring: Adapter ring sold separately to mount the holder to a specific lens diameter.
