Urth Lens Filter Plus+ - 77mm ND64

A Neutral Density (ND) filter reduces the amount of light entering your camera lens without affecting the color balance of the image. This allows for creative control in various lighting conditions.

'6 Stop' refers to the amount of light the filter reduces. It means the filter cuts down the light by a factor of 2^6, or 64 times, allowing you to use shutter speeds 64 times longer or decrease your aperture by 6 stops.

Yes, this filter is excellent for videography. It helps achieve the correct shutter speed for cinematic motion blur in bright light and can also be used to create a shallow depth of field effect.

The Urth ND64 filter features an ultra-slim rim designed to minimize or eliminate vignetting, even on wide-angle lenses. However, very extreme wide-angle lenses might still show slight effects at their widest settings.

This is a fixed 6-stop ND filter, meaning it always provides a consistent 6 stops of light reduction. Variable ND filters allow you to adjust the amount of light reduction, offering more flexibility but can sometimes introduce color casts or 'X' patterns at their extreme ranges.

The Plus+ designation typically indicates advanced coatings and superior glass quality, such as the 20-layer nano-coating and SCHOTT glass used in this filter, ensuring higher light transmission and clarity compared to standard versions.

Urth filters are backed for life, offering peace of mind against manufacturing defects.

Ensure the 6-stop reduction is appropriate for the current lighting conditions. You may need to increase your ISO or use a slower shutter speed than initially intended, or consider a filter with less stop reduction if available.

Confirm the filter is screwed on straight and that the ultra-slim rim is not obstructed. While designed to prevent vignetting, extreme wide-angle lenses might still show minor effects at their widest focal lengths.

The 20-layer nano-coating is designed for color neutrality. If a cast is present, try recalibrating your camera's white balance or adjust color in post-processing. Ensure the filter glass is clean.
