Tiffen Variable Neutral Density Filter Review: One Filter, Adjustable Exposure Control

The convenience of a variable filter

Rather than carrying several fixed-strength filters and swapping between them as lighting changes throughout a day, this filter lets a photographer or videographer simply twist a ring to dial in the needed exposure reduction on the fly.

This is particularly useful for run-and-gun video work where lighting conditions shift quickly between indoor and outdoor locations, and stopping to swap a physical filter would cost valuable time during a shoot.

Optical quality and color neutrality

At lower to moderate settings, color rendering stays reasonably clean and close to neutral, performing comparably to many fixed-strength filters in typical everyday use.

At the strongest end of the adjustment range, a more noticeable color shift and occasionally a faint cross-shaped pattern can appear, which is a known characteristic of variable neutral density filters generally and this one is not fully immune to it.

Build quality and ease of use

The rotating mechanism feels smooth and operates with enough resistance to stay in place once set, without being so stiff that quick adjustments become a struggle during active shooting.

The coating resists water droplets and fingerprints reasonably well, which is a practical convenience for anyone shooting outdoors in changing weather conditions throughout a session.

Where a fixed filter still wins

Photographers who need the cleanest possible color neutrality for a single consistent lighting condition, such as a dedicated landscape long exposure, will generally get better results from a quality fixed-strength filter instead.

The variable filter tradeoff makes the most sense for mixed-use scenarios where convenience and adaptability matter more than squeezing out the absolute cleanest result in every single shot.

Value for mixed photo and video use

For creators who shoot a mix of video and photography across varied lighting conditions, the cost savings and convenience of one adjustable filter over several fixed-strength alternatives is a genuinely practical consideration.

Buyers who already know they will mostly shoot in one consistent lighting scenario, such as always working at the strongest reduction for daytime video, may find a quality fixed filter a better long-term investment instead.

Practical tips for better results

Avoiding the very extreme end of the adjustment ring, where the cross pattern and strongest color shift tend to appear, and instead stacking a lighter setting with a slightly narrower aperture produces noticeably cleaner results in most situations.

Carrying a lens hood alongside this filter also helps reduce the chance of flare interacting poorly with the rotating glass elements, which is a small habit that meaningfully improves consistency across a shooting session.
