72mm Ultra-Low Reflectivity Putter Variable ND Filter ND2-ND400

In this review the 72mm Ultra-Low Reflectivity Putter Variable ND Filter ND2-ND400 is examined for photographers and videographers who need a single, adjustable neutral density solution. The bottom line: it is best for shooters who want reliable, high-definition reduction of light and minimal ghosting in backlit scenes. The filter's ultra-low reflectivity technology and AGC optical glass preserve sharpness while the push-pull putter adjustment makes changing stops quick and repeatable, so users can control exposure without swapping multiple filters.

Key Features

• Ultra-low Reflection Technology: Reduces reflectivity to 0.1% to minimize ghosting and preserve contrast in strong backlight.
• AGC Optical Glass: Polished flat glass surface maintains image sharpness and delivers high-definition results across stops.
• Unique Putter Adjustment: Push-pull lever and clearly marked stops from ND2 to ND400 enable precise, repeatable control over exposure.
• 28 Multi-Layer Coatings: Nano-level coatings improve water resistance, scratch resistance, and reduce surface reflections for durable performance.
• No Vignetting Design: A slim 7.4mm frame thickness avoids vignetting in most wide-angle shooting, tested beyond 19mm for photos.

Who It's For

The filter is aimed at hybrid shooters and videographers who need a compact variable ND that reduces ghosting and keeps images sharp when working in changing light. Its push-pull putter adjustment is particularly useful for videographers who want to fine-tune stops on the fly without altering aperture or ISO.

Less suitable are photographers who require absolute maximum stop ranges beyond ND400 or who prefer dedicated single-stop glass filters for ultimate optical purity; also those using very wide lenses under 17mm in video may need to check for their individual setup.

Pros & Cons

Pros

• Ultra-low reflectivity greatly reduces ghosting in backlit scenes.
• High-quality AGC glass and 28 multi-layer coatings preserve sharpness and resist smudges.
• Putter-style adjustment with clearly marked stops makes exposure changes fast and repeatable.

Cons

• Variable NDs can introduce slight color shifts in some setups, so color-critical work may need testing.

Our Verdict

The 72mm putter variable ND is a solid, value-oriented choice for photographers and videographers who want a single filter to control exposure while preserving sharpness and minimizing ghosting. Its ultra-low reflectivity and robust coatings make it a practical tool for backlit scenes and run-and-gun shoots; those needing absolute color neutrality or extreme wide-angle coverage should verify compatibility before committing.

Frequently Asked Questions

Will this cause vignetting on wide-angle lenses?
Real-world tests show no vignetting beyond 19mm for photos and beyond 17mm for video, but very wide lenses under those focal lengths should be tested with your setup.

How is the adjustment marked?
The frame includes a push-pull putter lever and clearly marked stops from ND2 to ND400 for precise, repeatable changes.

Is the glass durable in the field?
The filter uses AGC optical glass with 28 nano-level multi-coatings that provide water resistance, scratch resistance, and easier cleaning.
