Urth 72mm ND2-32 (1-5 Stop) Variable ND Lens Filter Plus+

ND2-32 refers to the range of light reduction. ND2 blocks 1 stop of light, while ND32 blocks 5 stops of light. This filter allows you to continuously adjust the density anywhere within that range.

The 'X-effect' is an artifact that can appear at the extreme ends of the variable ND range. This filter includes a min-max locking mechanism. Rotate the outer ring to your desired setting and then engage the lock to prevent over-rotation and the 'X-effect'.

Yes, this filter is excellent for videography, especially in changing light conditions. It allows you to maintain a consistent shutter speed (typically double your frame rate for natural motion blur) while adjusting aperture for depth of field, or vice versa.

The filter features an ultra-slim rim design to minimize vignetting. However, some vignetting may still occur on very wide-angle lenses (wider than 24mm on a full-frame camera). It's always recommended to test your specific lens and filter combination.

The 'Plus+' designation typically indicates enhanced features, such as the 20-layer nano-coating for superior light transmission and reduced reflections, as well as the enhanced min-max locking mechanism for better control and prevention of the 'X-effect'.

Use a blower brush to remove loose dust. For smudges, apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the glass. Avoid spraying solution directly onto the filter. Handle by the rim to prevent fingerprints.

Urth filters generally come with a limited lifetime warranty against manufacturing defects. Please refer to Urth's official website or your purchase receipt for specific warranty details and registration.

This 'X-effect' occurs when the filter is rotated beyond its intended range. Ensure the min-max locking mechanism is engaged before shooting, especially at higher stop settings. If it persists, try rotating the filter back to its lowest setting and re-engaging the lock.

Adjust the filter's outer ring to the desired stop reduction. Use your camera's live view or histogram to confirm the correct exposure. Ensure the filter is set to a value appropriate for the current lighting conditions.

Verify that the lens has a 72mm filter thread. Check for any debris or damage on the lens threads or the filter threads. If using a step-up ring, ensure it is compatible and securely attached.

Variable ND filters can sometimes introduce a slight color cast, particularly at their maximum settings. Try reducing the ND stop or bracket your shots to select the cleanest image in post-processing. This filter uses high-quality glass to minimize this effect.
