Marumi DHG ND64 Filter - 49mm

ND64 indicates the filter's strength. It means it reduces the light passing through by 64 times, which is equivalent to a 6-stop reduction in exposure.

Yes, you can stack filters, but doing so with multiple filters, especially thicker ones, increases the risk of vignetting and light loss. The thin frame of the DHG ND64 is designed to minimize this.

Diffraction occurs when light bends around the edges of the aperture blades, becoming more noticeable at very small apertures. The ND64 filter allows you to use a wider aperture in bright light, thus avoiding the need to stop down excessively and minimizing diffraction.

Yes, it can be useful for video to maintain a desired shutter speed (often twice the frame rate) in bright conditions, allowing for a cinematic motion blur.

ND filters reduce overall light intensity uniformly. Polarizing filters reduce reflections and enhance saturation by filtering out polarized light.

Check the front of your camera lens. The filter size is usually indicated by a symbol with a line through it, followed by a number (e.g., ø49mm). This filter is specifically for lenses with a 49mm thread size.

The ND64 filter reduces light by 6 stops. You need to compensate by increasing exposure time (e.g., multiplying shutter speed by 64) or opening your aperture by 6 stops.

While designed for true color balance, recalibration of your camera's white balance or post-processing correction might be needed, especially if shooting in mixed lighting conditions. Ensure the filter is clean.

This filter has a thin frame, but vignetting can still occur on very wide-angle lenses. Try using a slightly longer focal length or stopping down the aperture if possible (though this filter is designed to help avoid stopping down too much).
