A 49mm circular glass filter with multi-coated surfaces

HOYA Filter

HOYA Filter 49mm 2X (0.3) Neutral Density Multi Coated Glass Filter camera filter

SKU CH-EKYC-KMM3Z

A 49mm neutral density filter that cuts light by .3 stops for wider apertures or slower shutter speeds, with multi-coating to reduce flare

  • Reduces light by 0.3 density for balanced exposures
  • Multi-coated glass minimises flare and ghosting
  • Enables wider apertures for shallow depth of field
  • Allows slower shutter speeds to blur motion creatively
  • Maintains accurate colour rendition in bright conditions

Purpose and user

This 49mm neutral density filter reduces light by a factor of 2X (0.3) without shifting colour balance. It is built for photographers who need to keep a wide aperture or a slow shutter speed in bright conditions.

When the step up makes sense

The filter replaces shooting at a smaller aperture or a faster shutter when the scene is too bright for the desired depth of field or motion blur. The jump is worth it whenever you must hold a large aperture for subject separation or extend exposure time for creative motion effects.

Behaviour under sustained use

Multi-coated glass suppresses flare and ghosting even when strong light hits the front element repeatedly. The coating maintains contrast and colour fidelity across long sessions, so images stay clean without the degradation that uncoated filters can introduce.

  • Reduces light by 0.3 density for balanced exposures

Questions about this item

Will the 49mm thread size match my lens filter mount?

The filter uses a standard 49mm thread that screws directly onto any lens with a matching 49mm front diameter, so verify your lens cap or barrel for the Ø49 symbol before ordering.

How do I attach the filter without cross-threading the multi-coated glass?

Align the filter threads squarely with the lens barrel, turn gently clockwise until you feel the first thread engage, then continue rotating smoothly — forcing it at an angle is the common mistake that damages the coating.

How should I clean the multi-coated surface when it gets dusty or smudged?

Blow off loose particles with a rubber blower, then wipe lightly in a circular motion using a microfibre cloth dampened with dedicated lens fluid; avoid dry wiping or household cleaners that can degrade the coating.
