Irix Edge 29mm x 29mm Neutral Density Gel Filter Set (ND8, ND16, ND32, ND64, Clear)

For Irix lens owners who demand precise light control without adding bulk to the front of the lens, the Irix Edge 29mm x 29mm gel filter set offers a rear-mount solution that keeps your setup compact and your image quality pristine. Unlike screw-on filters that can cause vignetting on ultra-wide angles, these flexible gel filters slide into the dedicated rear slot of compatible Irix lenses, sitting close to the sensor where they maintain optical integrity across the entire frame. The set includes five carefully chosen densities—ND8, ND16, ND32, ND64, and a clear protective filter—giving you a full toolkit for long exposures, shallow depth of field in bright light, and everyday lens protection.

Highlights

• Five rear-mount gel filters: ND8 (3-stop), ND16 (4-stop), ND32 (5-stop), ND64 (6-stop), and clear protective filter
• 29 x 29 mm square format fits Irix lenses with rear filter slots, including 11mm f/4, 15mm f/2.4, 45mm f/1.4, and 150mm f/2.8
• High-quality optical gel construction ensures color neutrality and high resolution, preserving the sharpness of your Irix glass
• Flexible film design allows easy insertion and removal without risk of scratching the rear element
• Includes a protective storage envelope to keep filters clean and organized

In daily use

The rear-mount design is a game changer for wide-angle shooters. Because the filters sit behind the lens, you avoid the bulky filter holders and step-up rings that often intrude into the frame at focal lengths below 16mm. Switching densities takes seconds: just remove the lens, slide out the current filter, and insert the next one. The ND8 is perfect for smoothing water or clouds with a 3-stop reduction, while the ND64 lets you shoot at wide apertures in full sun for creamy bokeh. The clear filter adds a layer of protection for the rear element, especially useful in dusty or sandy environments. Each filter is cut precisely to 29 x 29 mm, ensuring a snug fit without light leaks.
