This Urth 46mm ND2-32 Variable ND Lens Filter Plus+ is designed for photographers seeking creative control in changing light conditions, enabling shallow depth of field and motion blur effects. It features a locking mechanism to prevent the 'X' effect and offers 1-5 stops of light reduction. While excellent for nature and landscape photography, users should be mindful of potential slight color shifts at extreme settings.

A Variable ND filter reduces the amount of light entering the lens, allowing you to use slower shutter speeds or wider apertures in bright conditions. It works by combining two polarizing filters that can be rotated against each other to control the amount of light blocked.
The 'X' effect, or cross-polarization, appears as an 'X' pattern of darkening across the image, usually at higher ND settings. The Urth Variable ND Plus+ features a min-max locking mechanism designed to prevent over-rotation and thus avoid this effect.
ND2-32 indicates the filter can reduce light by a range of 1 to 5 f-stops. ND2 corresponds to 1 stop, and ND32 corresponds to 5 stops of light reduction. Other filters might have different ranges, like ND8-1000 (3-10 stops).
Yes, this filter is excellent for video, especially when you need to achieve a specific shutter speed for motion blur (e.g., the 180-degree rule) in varying light conditions.
Use a soft lens brush to remove loose dust. For smudges or fingerprints, use a lens cleaning solution applied to a microfiber lens cloth. Wipe gently in a circular motion from the center outwards.
The 'Plus+' designation typically indicates enhanced features such as advanced nano-coatings, specific glass quality (like German SCHOTT), and robust construction compared to standard models.
The ultra-slim rim design helps prevent vignetting. However, on very wide-angle lenses (wider than what a 46mm filter thread typically accommodates), some vignetting may still occur, especially at extreme ND settings. Always test on your specific lens.
This usually indicates the filter has been rotated beyond its intended range. Ensure the filter is set between the 'ND' and '32' (or 1 and 5 stop) markings and that the locking mechanism is engaged correctly.
This can occur at the extreme ends of the variable ND range. Try adjusting the filter to a slightly lower or higher stop. For critical color work, consider using a fixed ND filter or be prepared to correct color in post-processing.
Ensure you are using the correct thread size (46mm) and that there is no debris on the lens threads or filter threads. Try screwing it on gently and straight, without cross-threading.
Setup:
Screw the Urth 46mm ND2-32 Variable ND Lens Filter Plus+ onto the front filter thread of your 46mm lens. Ensure it is screwed on securely but not overtightened. To adjust the ND level, gently rotate the outer ring of the filter until the desired stop (1-5) is reached, indicated by the markings. The min-max locking mechanism helps secure your chosen setting and prevents accidental rotation.
Compatibility:
This filter is specifically designed for lenses with a 46mm front filter thread. It is compatible with most camera systems that utilize 46mm lenses. Check your lens's specifications for the correct filter size.
