Irix Edge Gelatin Filter Set consists of fifteen gelatin filters with three density factors: 0.6 (ND4), 0.9 (ND8) and 1.2 (ND16).
Each filter was made with ultra-thin (0.1mm) high-quality film to keep the image free of optical aberrations and distortions. Thanks to the square shape and rounded corners, the filters easily fit to Irix lenses equipped with rear filter slot size 30 x 30mm. Irix Edge Gelatin Filter Set is a convenient option for photographers who want to obtain a longer shutter speed with Irix 11mm f/4.0 or use ND filter with screw-in polarizer on Irix 15mm f/2.4 at the same time.
