Our Variable ND2-400 Filter provides 1 to 8.66 f-stops of light reduction, giving you greater creative control in changing light.

$119 AUD


By blocking 1 to 8.66 f-stops, you can use wider apertures in variable light for shallower depth of field effects, and slower shutter speeds for long exposure effects without overexposing your images.

Cinematographers can use our ND2–400 Variable ND Filter to create more cinematic effects in low and bright light.

For wide-angle and telephoto lenses, we recommend our Variable ND2-32, ND8-128, ND64-1000 or fixed ND filters.

How to Use

Variable ND2-400 (1-8.65 Stop) Filter


Find your filter size
Inquisitively search lens for diameter symbol. Ø often marks the spot. The diameter you seek may be accompanied by a number Ø58 or 58mm. Look to the side and the front this precious number is your filter size. Be warned: your lens focal length (e.g. 18-55mm) is not your filter size.

Place flat and screw clockwise
Excitedly behold lens in one hand and place flat on lens. Gently screw clockwise until just firm. Do not over-tighten that which goes on must one day come off.

Slow your shutter

Open your aperture
Or, you can adjust for the darkening by opening up your aperture, which creates a shallower depth of field. You can also combine both exposure setting adjustments.

Frequently Asked Questions

Which Variable ND Filter should I buy?

It depends on the conditions you’ll be shooting in and the effects you want to achieve.

Our Variable ND2-32 is made for low-light, our Variable ND2-400 and ND8-128 are for low-light and bright light, and our ND64-1000 is specifically for harsh bright light and long exposure.

Should I buy a fixed or variable ND filter?

It depends on how, where and what you’ll be shooting.

Fixed ND filters block a fixed f-stop of light from entering your camera. Variable ND filters provide more flexibility and have a range of f-stops you can block by rotating the outer element. If you’re starting out with ND filters, we recommend a Variable ND so you have more flexibility while you’re learning how to shoot with an ND. If the light is likely to change often, a Variable ND saves you changing between fixed NDs each time.

Do Urth ND filters have a colour cast?

No, they have great colour neutrality.

There are a couple of reasons your images may show a slight colour cast when using an ND filter. Check your white balance settings. By restricting the light entering your camera, it may throw out your white balance settings. Manually adjust your white balance settings to reduce any colour cast.

What’s the best Variable ND filter for wide-angle and telephoto lenses?

Our whole range of Fixed ND Filters work with wide-angle and telephoto lenses.

Our ND filters have ultra-slim rims to avoid any vignetting issues. Our Fixed ND Filters are all in our professional Plus+ range and use the world’s best glass, making them perfect for wide-angle and telephoto lenses.

Do I need to step-up my lens cap for Urth Variable ND Filters?

No, our Variable ND Filters take the same size lens cap.

If your lens takes a 67mm Urth Variable ND Filter, your 67mm lens cap will fit perfectly. Some variable ND filters require you to step-up a size, but not Urth.

Perfect ND filter!

I waffled a while over which ND filter to buy, and ended up settling on this one over the higher-grade Urth+ VNDs because I don't use a VND all that often these days. I was expecting some slight tradeoffs with image quality or color since this is the standard Urth grade, but to my surprise it's an absolutely stellar performer. In my brief early tests and then a year of occasional use real-world since, I've never noticed any negative effects to my images, other than a tiny bit more flaring and the typical effects of polarization that all VNDs have (but even these are beautifully controlled). I honestly cannot imagine how the Urth+ can be any better. Best VND I've ever used, and the best value by miles. This is the filter that completely sold me on Urth.
