  • 1-stop light reduction from 0.3 density for wider apertures in bright light

Hoya SOLAS IRND 0.3 72mm Filter

The Hoya SOLAS IRND 0.3 is a 72mm infrared neutral density filter designed for digital cameras. It reduces incoming light by 1 stop using a density of 0.3. The filter suppresses infrared contamination evenly across the frame to maintain consistent colour balance.

Suited for photographers needing slight light

This filter suits photographers who want wider apertures or slower shutter speeds in bright conditions without colour shifts. It is not for users who need stronger light reduction such as 2 stops or more. Buyers with lens threads other than 72mm must choose a different size.

72mm thread and 0.3 density

The filter fits lenses with a 72mm front thread and provides a fixed density of 0.3 for 1 stop of light reduction. Other available densities include .6, .9, 1.2, 1.5, 1.8, 2.7 and 3.0. Thread sizes range from 46mm to 82mm.

Questions about this item

Will the 72mm thread fit my lens filter mount?

The filter uses a standard 72mm front thread, so it screws directly onto any lens with a matching 72mm filter diameter.

How do I install it without cross-threading the aluminium ring?

Align the filter squarely, turn gently until the threads catch, then rotate clockwise until snug — do not force it past the first point of resistance.

Does the IR-blocking coating degrade and need replacement?

The IR suppression is built into the glass substrate, not a surface coating, so it does not wear out or require periodic replacement.
