67mm ND1000000 (20 Stops) ND Neutral Density Lens Filter - Extreme

In this review the reviewer finds the K&F CONCEPT 67mm ND1000000 (20 Stops) filter is best for photographers who need extreme exposure reduction for solar, long exposure, or creative motion work. The bottom line: it delivers very strong, consistent attenuation with a high-quality build that makes difficult shots possible, especially eclipse and sun photography. While it is notably dark, that darkness is the point - when used correctly it allows safe sun imaging and long-exposure effects that are impossible with weaker filters.

Key Features

• 20 stops ND density: Provides extreme light reduction so photographers can shoot direct sun and capture long exposures in bright daylight without overexposure.
• 67mm filter thread: Screws onto lenses with a 67mm thread for a secure, lens-matched fit and straightforward mounting and removal.
• 28 multi-layer coatings: Reduces reflections and preserves natural color for clearer images and more accurate tonal rendering.
• Robust construction: Solid build quality gives confidence when using the filter for critical shots like eclipses and sunspots.
• Ease of use: Simple screw-on design and reliable fit make it quick to attach and detach in the field.

Who It's For

Photographers who capture solar events, eclipse sequences, or need extreme long exposures in full daylight will appreciate this filter. It is tailored to users who require reliable, heavy attenuation and expect a durable accessory that keeps color fidelity intact thanks to the multi-layer coatings.

This is not aimed at casual users who want subtle ND effects or those who need a variable density solution; the filter is very dark and best suited to specialized shooting scenarios where 20 stops of reduction is required.

Pros & Cons

Pros

• Exceptional light reduction enables safe sun photography and dramatic long-exposure effects.
• High build quality and a precise fit make mounting and removal straightforward.
• Multi-layer coatings help maintain natural color and reduce unwanted reflections.

Cons

• Extremely dark density can be too much for general-purpose use and requires careful exposure planning.
