The Urth Variable ND2–32 Filter Pro is a variable neutral density filter providing 1–5 stops of light reduction for controlled exposure in bright conditions. It uses SCHOTT B270 optical glass and a 34-layer CoraNano™ Max coating to keep colour neutral while reducing reflections and flare. The fixed rotation range gives you better precision when adjusting exposure without exceeding the usable range or introducing uneven results.
Urth Variable ND2–32 Filter Pro Key Features:
- Variable ND filter providing 1–5 stops controlled light reduction
- Adjustable density supports motion blur and aperture control in daylight
- SCHOTT B270 optical glass maintains colour accuracy and image clarity
- CoraNano™ Max 34-layer coating reduces reflections and improves transmission
- True Colour output maintains neutral tones without visible colour shift
- Ultra-low reflectance reduces flare and ghosting in strong light
- Defined rotation range for precise and repeatable exposure adjustment
- Hard-stop design prevents over-rotation beyond usable density range
- Aluminium frame maintains alignment and resists warping over time
- Hydrophobic coating resists water, oil and fingerprint build-up
- Slim frame profile helps minimise vignetting on wider lenses
- Lifetime warranty supports long-term professional use
FAQs:
Does this filter affect colour accuracy?
No, the filter is designed to maintain neutral colour across the full 1–5 stop range. You don’t see the typical colour shift that can appear with lower-quality variable ND filters. This is especially important for video or sequence work, where consistency between frames needs to be maintained without correction.
Does the filter keep exposure even across the frame?
Yes, within its intended 1–5 stop range. The filter includes hard stops to keep rotation within the usable range, helping prevent the cross-pattern effect that can occur when a variable ND is pushed too far.
How well does the filter maintain image sharpness?
The SCHOTT B270 optical glass effectively preserves detail and contrast. In practical use, there is no noticeable softening, and image quality remains consistent across the frame. It performs much more closely to a fixed ND filter than entry-level variable ND options.
Is the rotation precise enough for video work?
Yes, the continuous rotation across the 1–5 stop range gives you fine control over exposure. This makes it easier to hold a consistent shutter speed or aperture as light levels change, which is particularly useful when filming in daylight.
What difference does the coating make?
The 34-layer CoraNano™ Max coating reduces reflections, helping to control flare and maintain contrast in bright conditions. It also resists water, oil, and fingerprints, making the filter easier to keep clean when working outdoors or handling it regularly.
