ND64 indicates the filter's strength. It reduces the light entering the lens by 6 stops, meaning it allows only 1/64th of the light to pass through compared to no filter.

Yes, you can stack this filter with other filters like polarizers or UV filters, but stacking increases the risk of vignetting and internal reflections, especially with wider lenses.

Yes, it is highly recommended for videography to achieve correct shutter speeds for motion blur in bright conditions.

This is a fixed 6-stop ND filter, offering consistent quality and color accuracy. A variable ND filter can be adjusted to different strengths but may introduce color shifts or X-patterns at extreme settings.

In most cases, autofocus performance should remain largely unaffected. However, in extremely low light conditions caused by the filter, autofocus might struggle more than without the filter.

The thin frame is designed to prevent vignetting, which is the darkening of the corners of the image, particularly when using wider-angle lenses.

Gently remove dust with a lens brush. For smudges, use a clean microfiber cloth lightly dampened with lens cleaning solution. Avoid harsh chemicals or abrasive materials.

Ensure the filter is the correct size for your lens and that you are not using a very wide-angle lens where even thin filters can cause issues. Try removing lens hoods or extensions if possible.

This filter is designed for true color. If a color cast is present, it may be due to camera white balance settings or post-processing. Ensure your white balance is set correctly or adjust in post.

Verify that you have the correct 67mm size. Ensure the lens threads are clean and free of debris. Screw the filter on gently and straight.

Ensure the filter is clean and free from smudges or dust. The special coatings are designed to minimize this, but a dirty filter will impact image quality.
