ND8 Neutral Density Multicoated Glass Filter 67mm - 3 Stop Reduction

In this review the ND8 (0.9) Multicoated Glass Filter is examined for photographers who use the Tamron 28-75mm f/2.8 zoom and need reliable 3-stop light reduction. The bottom line: this filter is for shooters who want solid neutral density control without color cast and with long-lasting durability. The reviewer found the filter's Schott glass construction, double-layer multi green coating and slim profile deliver predictable exposure control and minimal vignetting when used on wide-angle to short-telephoto zooms.

Key Features

• Solid ND 0.9 (3 stops): Provides consistent exposure reduction useful for motion blur and controlling depth of field in bright conditions.
• Schott Glass Construction: High quality glass helps preserve sharpness and reduces optical artifacts compared with lower-grade materials.
• X Optical Nano Coating: Two-layer nano coating repels water and oil, making cleaning easier and keeping images clear in damp conditions.
• Slim Design: The reduced thickness minimizes vignetting on the Tamron 28-75mm zoom, especially at wide focal lengths.
• Multi Green Double Layer Polish: Multi-coated surfaces help reduce reflections and maintain neutral color balance across exposures.
• Durability Features: Scratch resistant finish plus a 10 year warranty gives confidence for active field use.

Who It's For

The ND8 filter is aimed at hobbyists and pros who frequently shoot landscapes, waterfalls, or video with the Tamron 28-75mm f/2.8 and want a reliable 3-stop reduction to lengthen shutter times or allow wider apertures in bright light. It is especially useful for photographers who value optical consistency and easy maintenance thanks to water and oil repellant coatings.

Photographers seeking variable density control or extreme light reduction (more than 3 stops) should look elsewhere; likewise those requiring filters for very wide full-frame lenses beyond the 67mm thread system will need a different size or adapter solution.

Pros & Cons

Pros

• High quality Schott glass preserves image sharpness and minimizes aberrations.
• Multi green double-layer polish and two-layer nano coating reduce reflections and ease cleaning.
• Slim profile helps avoid vignetting on wide-angle settings of the 28-75mm zoom.

Cons

• Fixed 3-stop density is limiting if variable or stronger reductions are required.

Frequently Asked Questions

Will this cause vignetting on the Tamron 28-75mm?
Its slim design is intended to minimize vignetting on that zoom; wide-open extreme wide angles may still show slight darkening depending on the lens and camera.

How much light does ND8 block?
ND8 is a 0.9 density that reduces light by 3 stops, suitable for slowing shutter speeds and widening apertures in bright conditions.

Is the coating durable in the field?
The two-layer X Optical Nano coating repels water and oil and the filter is scratch resistant, backed by a 10 year warranty for long-term use.
