Urth Magnetic ND Selects Filter Kit - 77mm

ND stands for Neutral Density. An ND filter reduces the amount of light entering the camera lens without affecting the color balance, allowing for longer shutter speeds or wider apertures.

The numbers indicate the amount of light reduction. ND8 reduces light by 3 stops, ND64 by 6 stops, and ND1000 by 10 stops. Higher numbers mean more light reduction.

Yes, the magnetic adapter ring must be attached to the lens you intend to use the filter with. You will need a separate adapter ring for each lens thread size you wish to use these filters on.

While technically possible due to the magnetic system, stacking ND filters can lead to unpredictable color casts and potential loss of image quality. It is generally recommended to use a single filter for optimal results.

Use a soft microfiber lens cloth to gently wipe the surface. For tougher smudges, apply a small amount of lens cleaning solution to the cloth, not directly to the glass, and wipe gently.

Yes, these filters are excellent for video as they allow you to achieve desired shutter speeds (e.g., 1/50th for 24fps) in bright conditions, enabling proper motion blur and depth of field.

Urth offers a lifetime quality warranty on their magnetic lens filters.

Ensure the magnetic adapter ring is securely screwed onto the lens and is clean. Check that the filter itself is clean and free of debris.

Verify that the correct filter size (77mm) is being used for the lens. Ensure the ultra-slim rim is seated properly; some wide-angle lenses may still show slight vignetting depending on their design.

This is rare with high-quality glass. Ensure the lens and filters are clean. Recalibrate your camera's white balance if the cast persists.

Gently pull the filter away from the adapter ring. If it's stuck, try rotating it slightly while pulling. Ensure no dirt or debris is impeding removal.
