67mm Putter Variable ND Filter ND2-ND400 (1-9 Stops) - Precision

In this review the K&F CONCEPT 67mm Putter Variable ND Filter is assessed as a practical, budget-friendly tool for stills and video shooters who need flexible light control. The single biggest reason to consider this filter is its precise putter-style frame with clearly marked stops from ND2 to ND400, which makes incremental exposure changes fast and repeatable for time-lapse, long exposures, or controlled motion blur. It uses Japanese AGC optical glass and extensive coatings, so image quality is the chief selling point for photographers who want variable density without replacing multiple filters.

Key Features

• Import Optical Glass: Crafted from Japanese AGC glass with 28 multi-layer coatings to reduce reflections and preserve contrast.
• Putter Design for Precision: The putter-style frame gives tactile, marked stops so users can dial exact exposure reductions quickly.
• Wide Range: Adjustable from ND2 to ND400 (1 to 9 stops) to cover most bright-light and creative long-exposure situations.
• Waterproof and Scratch Resistant: Hydrophobic, oil-proof, and scratch-resistant coatings protect both surfaces for field durability.
• Ultra-Slim Frame: A 7.4mm ultra-slim frame is designed to avoid vignetting even on wide-angle lenses.
• Compatibility Note: Threads fit 67mm lenses; users will need a 72mm lens cap to fit this filter.

Who It's For

The filter is best for enthusiast photographers and videographers shooting outdoors who want a single, compact solution for variable exposure control. Landscape photographers doing long exposures and creators who need quick stop adjustments during handheld or tripod filming will appreciate the marked increments and smooth rotation.

It is less suited to those who demand absolute zero color shift at extreme stops or professionals requiring interchangeable solid ND sets for critical color workflows; some users report mixed color cast and occasional fiddliness when finding the exact stop, so heavy color-critical studio work may be better served by fixed, calibrated NDs.

Pros & Cons

Pros

• Solid build and multi-layer coatings deliver strong perceived value and durable optics.
• Putter-style frame with stop markings makes exposure adjustments repeatable and precise.
• Ultra-slim 7.4mm frame reduces the chance of vignetting on wide-angle lenses.
• Waterproof and oil-resistant coatings make it suitable for outdoor, adventurous use.

Cons

• Some users note mixed reports of color cast at darker settings, so expect minor color shifts in some situations.
• Functionality and ease of use receive mixed feedback; adjusting to the exact stop can take time for a few users.

Frequently Asked Questions

Will this filter vignette on wide-angle lenses?
Its ultra-slim 7.4mm frame is designed to minimize vignetting and is suitable for ultra-wide use, including around a 16mm focal length on compatible cameras.

Which lenses will this fit?
It fits lenses with a 67mm filter thread; check the lens barrel for the diameter symbol and thread size before ordering.

Does it cause color cast?
Most users report acceptable color performance thanks to the multi-layer coatings, but some customers observe a visible color cast at darker settings, so test on your setup if critical color is required.
