Urth 62mm ND8 (3 Stop) Lens Filter Plus+

'ND8' refers to the filter's designation, and '3 Stop' quantifies its light reduction capability. It means the filter reduces the amount of light entering your lens by 3 f-stops, or to 12.5% of its original intensity.

Yes, the ultra-slim rim design allows for stacking with other Urth filters, though excessive stacking, especially on wide-angle lenses, may lead to vignetting.

By reducing the amount of light, the ND filter allows you to use a wider aperture (e.g., f/1.8 or f/2.8) in bright conditions to achieve a shallower depth of field and background blur, without overexposing the image.

Yes, it's excellent for videography. It helps maintain a consistent shutter speed (typically twice the frame rate) in bright light, which is crucial for achieving cinematic motion blur and avoiding a choppy look.

The 'Plus+' designation typically indicates advanced features such as 20-layer nano-coating for superior cleaning, protection, and light transmission, compared to standard coatings.

Look for the filter thread size marked on the front of your lens, usually indicated by a circle with a line through it, followed by a number and 'mm' (e.g., ø62mm).

Ensure you are using the correct filter size (62mm) for your lens. Check for any debris in the lens threads or on the filter threads. Try gently aligning the filter before screwing.

Confirm the filter is clean. The high-quality SCHOTT glass is designed for neutral color rendition, so a cast usually indicates a need for cleaning or a potential issue with your camera's white balance settings.

While the ultra-slim rim minimizes this, stacking multiple filters or using very wide-angle lenses can still cause vignetting. Try removing other filters or cropping slightly in post-processing.
