This 77mm Marumi DHG Solid NDSolar Eclipse Filter provides a 16.5-stop exposure reduction. Its 5.0 density creates a darkening of the entire image that is effective for solar eclipse photography. You can also use it to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
To prevent internal ghosting and reflections, each glass surface has nine multiple layers of antireflection coating. This Digital High Grade (DHG) coating also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters.
Constructed from optical glass for clarity as well as color fidelity, it features a durable yet lightweight aluminum-alloy filter ring.
Designed specifically for photography applications, it is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.
