72mm ND1000000 20-Stop Neutral Density Filter - Eclipse & Long

Our review of the 72mm ND1000000 20-stop neutral density filter finds it best suited for photographers who need extreme light reduction for solar and long-exposure work. The bottom line: this filter delivers massive attenuation and a solid, well-machined fit so users can safely photograph the sun or push exposures for motion blur and creative long-exposure effects. Build quality and optical neutrality are the single biggest reasons to consider it, and the filter is particularly useful for eclipse enthusiasts and landscape shooters who require precise darkening without strong color shifts.

Key Features

• 20 stops of light reduction: Allows very long exposures and safe direct sun viewing and photography when used correctly, enabling creative motion blur and eclipse imaging.
• 72mm filter size: Threads onto compatible 72mm lenses for a secure fit and straightforward attachment and removal.
• ND1000000 density: Provides extreme attenuation for precise control over exposure and effectively blocks intense light sources.
• 28 multi-layer coatings: Designed to reduce reflections and help maintain natural color balance and image clarity across exposures.
• Durable construction: Customers report robust build quality that stands up to regular use and handles lens mounting cleanly.

Who It's For

Photographers who capture solar events, eclipse sequences, or creative long exposures will find this filter valuable because of its extreme light-blocking capability and reliable fit. Landscape photographers wanting dramatic motion-smooth water and cloud streaking can push exposure times far beyond what ordinary ND filters permit.

It is not ideal for casual daylight photography where such a deep filter is unnecessary, or for users who need variable attenuation without swapping filters. Also, some photographers may find the darkness excessive for general use and should consider lower-stop ND options instead.

Pros & Cons

Pros

• Excellent for eclipse and sun photography, letting users see sunspots clearly when used appropriately.
• High build quality and a secure, easy-to-fit thread that customers report fits lenses well.
• Multi-layer coatings support natural color and reduce unwanted reflections in strong light conditions.

Cons

• Extreme darkness can be too much for many everyday shooting situations, limiting general purpose use.
• Because of the high density, precise framing and focusing require care and often must be done before attaching the filter.
