Irix Edge 100mm Soft Gradual ND Square Filter

A soft graduated neutral density filter darkens the top of the frame and fades gradually into clear, which is what holds detail in a bright sky without leaving a visible line across the image. The soft transition is the one to reach for when the horizon is broken by trees, buildings or hills.

These are 100 x 150 mm rectangles for the Irix Edge IFH-100 and IFH-100-PRO holders, so the gradient can be slid up and down to place the transition. Nano IR construction, multi-layer anti-reflective coatings and a double-sided NANO hydrophobic and oleophobic layer are standard; SR versions use toughened Super Resistant glass.
