6 Best 72mm ND Filters Reviewed: K&F Concept Top Picks

Picking the right 72mm ND filter comes down to more than matching the thread size on your lens. Glass quality, coating count, variable range, and whether you need a combined polarizer all affect what you’ll actually see in your images. The market is dense with options at every quality tier, and the differences between them aren’t always obvious from a product listing.

All six picks here come from K&F Concept’s filter lineup , a brand that has built a credible reputation in the budget-to-mid-range filter space. For broader context on filter types, coatings, and how ND fits into a complete filtration system, the Lens Filters hub is a good starting point.

Top Picks

K&F Concept 82mm Variable ND2-ND400 ND Lens Filter (B-Series)

The K&F Concept 82mm Variable ND2-ND400 (B-Series) is the entry point in this lineup , a straightforward variable ND that covers 1 to 9 stops of light reduction. That range handles most outdoor scenarios: bright midday shooting, slowing water movement to silk, extending shutter speeds for intentional motion blur in landscape work.

The B-Series sits at the base of K&F’s variable ND hierarchy, which means fewer coating layers than the Nano-X options above it. Owner reports note that the glass performs acceptably through the mid-range of the adjustment dial, but dialing toward the ND400 extreme invites the cross-pattern artifact common to dual-polarizer variable designs. That’s not a flaw unique to K&F , it’s a physics constraint , but it’s worth understanding before buying.

For photographers who want to experiment with variable ND before committing to a higher-tier option, the B-Series makes a reasonable first filter. Verified buyers consistently describe it as a functional introduction to ND work at an accessible price point.

K&F Concept 82mm True Color Variable Fader ND2-32 with CPL (Nano-X Series)

The K&F Concept 82mm True Color Variable Fader ND2-32 with CPL addresses two of the most common complaints about budget variable NDs: color cast and the lack of polarization control. The “True Color” designation refers to K&F’s optical design aimed at neutral transmission , keeping your whites white and your shadows unshifted as you rotate through the ND range.

The combined ND-plus-CPL design is the main functional argument here. Rather than stacking a separate circular polarizer over your ND (which adds glass elements, introduces vignetting risk, and requires two adjustment rings), this filter handles both functions in a single frame. For travel photographers or anyone who keeps their kit lean, that consolidation is genuinely useful. The CPL layer cuts reflections off water and glass independently of the ND adjustment.

Nano-X glass involves more coating layers than the B-Series, and owner consensus suggests the color neutrality claim holds reasonably well through the ND2-32 range. The narrower variable range , stopping at ND32 rather than ND400 , trades extreme light reduction for better image quality across the usable band.

K&F Concept 82mm Putter Variable ND2-ND400 (Nano-X Series)

The K&F Concept 82mm Putter Variable ND2-ND400 brings the wide 1-to-9-stop range of the B-Series into the Nano-X coating tier. The 28-layer multi-coating is the key upgrade: more coating layers mean better flare resistance, reduced surface reflection, and improved color fidelity compared to single- or lightly-coated alternatives.

The AGC glass designation refers to the optical glass substrate , a quality marker that separates this from filters built on standard float glass. Owner reviews note better sharpness retention at mid-range ND settings compared to the B-Series, which aligns with what the coating count would predict. The cross artifact still appears near ND400, as it will on any dual-polarizer design, but the optical floor is meaningfully higher here.

This filter suits photographers who want the flexibility of a wide variable range without sacrificing image quality in the mid-range stops where most variable ND work actually happens. Landscape and long-exposure photographers in particular will use the ND64-ND200 portion of the range most frequently, and that’s where the Nano-X glass earns its place.

K&F Concept 82mm Variable ND2-ND32 No X Cross (Nano-X Series)

The K&F Concept 82mm Variable ND2-ND32 No X Cross makes an explicit engineering trade-off: it caps the variable range at ND32 (5 stops) specifically to eliminate the cross-pattern artifact. By limiting how far the polarizer planes can rotate relative to each other, K&F removes the condition that generates the X-cross. The result is a filter where every position in the adjustment range produces clean, usable images.

For video shooters, this distinction matters significantly. Motion blur from ND work is most commonly needed in the ND4-ND32 range to maintain the 180-degree shutter rule , you rarely need ND400 for video exposure control outdoors. Eliminating the artifact risk across the full dial range makes this a more reliable option on set than wider-range filters where you have to manage an unusable zone.

The 28-layer Nano-X coating and waterproof treatment round out a filter that prioritizes reliability over extreme range. Owner reports consistently describe clean corner-to-corner rendering and no detectable color shift through the ND2-32 span.

K&F Concept 82mm Variable ND2-32 with CPL (Nano-X PRO Series)

The K&F Concept 82mm Variable ND2-32 with CPL (Nano-X PRO Series) steps up to 36 coating layers , the highest count in this lineup , and combines ND and CPL function in a single waterproof, scratch-resistant frame. The PRO designation reflects incremental improvements over the standard Nano-X: tighter manufacturing tolerances, better scratch resistance, and a more durable frame construction.

The 36-layer coating count is meaningful in real shooting conditions. More coating layers translate to better flare suppression in backlit scenarios, more consistent color transmission across the filter diameter, and improved durability over extended outdoor use. Photographers shooting near water , saltwater spray in particular , will appreciate both the waterproofing and the robust frame.

This is the strongest option in the lineup for photographers who want the ND-CPL combination and are willing to invest in a higher-quality build. The combination filter approach remains a practical space-saver, and the PRO-tier coatings make it a more confident choice for work where optical quality is non-negotiable.

K&F Concept 82mm Variable Fader ND2-32 with CPL (Nano-D Series)

The K&F Concept 82mm Variable Fader ND2-32 with CPL (Nano-D Series) occupies an interesting position in K&F’s lineup. The Nano-D designation represents a different optical design path from Nano-X , K&F positions the two as parallel mid-range options with slightly different optimization priorities rather than a strict hierarchy.

Like the Nano-X ND-CPL options, this filter handles both neutral density and circular polarization in one frame, with the ND2-32 range kept narrow enough to avoid cross artifacts throughout. Owner reports note competitive sharpness performance and clean color rendering. Where some buyers report a slight handling difference from Nano-X frames , a marginally different rotation feel on the adjustment ring , the optical output is comparable.

For buyers who encounter this series at a price point between the standard Nano-X and the PRO, the Nano-D is a legitimate choice rather than a downgrade. The waterproof treatment and multi-layer coatings meet the same practical standard as the comparable Nano-X options.

Buying Guide

Fixed vs. Variable ND , Choosing the Right Approach

Fixed ND filters provide a single, precise stop value , ND4, ND8, ND64, ND1000 , while variable NDs let you dial between a range with one filter. Variable ND filters offer flexibility at the cost of some optical complexity: the dual-polarizer mechanism that enables adjustment introduces the X-cross artifact risk near extreme rotation positions. For photographers who shoot across varied conditions without swapping filters, a well-chosen variable ND handles the majority of scenarios. For photographers who need a specific stop value with zero optical compromise , long-exposure landscape work at exactly ND1000, for instance , a fixed ND is the cleaner solution.

The filters in this roundup are all variable NDs, which reflects where most buyers’ needs land. The tradeoff is real but manageable once you understand it.

Variable Range: ND2-32 vs. ND2-400

A filter’s variable range tells you both its flexibility and its optical compromises. Wider ranges (ND2-400) offer more stops of control but introduce more severe cross-artifact behavior near the high end. Narrower ranges (ND2-32) eliminate the artifact zone entirely by keeping the polarizer rotation within bounds where clean images are possible throughout.

For outdoor photography in variable light , overcast to bright sun transitions, dusk shooting, golden-hour work , the ND2-32 range covers the practical majority of scenarios. For extreme long exposures in full daylight (shooting waterfalls at midday without a tripod), you may want ND64 or beyond, which pushes toward the wider-range options. Match your range to your primary use case rather than defaulting to the widest option available.

Coating Count and Glass Quality

Filter coatings serve two functions: reducing surface reflections (which cause flare and contrast loss) and protecting the glass surface from moisture, dust, and abrasion. The difference between a single-coated filter and a 28- or 36-layer multi-coated filter is visible in side-by-side comparisons , particularly in backlit scenes and situations with strong specular highlights.

AGC-designation glass and high coating counts are what separate K&F’s Nano-X and PRO tiers from the base B-Series. If you shoot frequently in challenging light or outdoors in wet conditions, the added coatings earn their place. For controlled studio or indoor use, the optical gap narrows. The full breakdown of how coating layers affect filter performance is covered in depth on the filter types and quality tiers reference page.

ND-CPL Combination Filters , When They Make Sense

Three options in this lineup combine neutral density with a circular polarizer in a single filter frame. Stacking separate ND and CPL filters adds two or more glass elements to your optical path, increases vignetting risk (especially on wide lenses), and requires managing two adjustment rings. The combination approach solves all three problems.

The trade-off is that you’re committing to using both functions simultaneously , you can’t use just the CPL layer when you want polarization without light reduction. For most outdoor scenarios where you’d want a CPL (cutting surface reflections on water, deepening sky contrast), you’re also typically fighting excess light, so the pairing is practically sound. Travel photographers and outdoor shooters with minimal kit space will find the combined filter the more useful choice.

Frame Build and Filter Handling

Frame construction affects how the filter mounts, rotates, and holds up over time. Thin frames reduce vignetting on wide lenses but offer less rotation grip. Waterproof-treated frames , standard across the Nano-X and Nano-D options here , resist moisture infiltration at the frame seal and allow cleaning without risk of water working into the frame bond.

Verified buyers across the K&F lineup note that the adjustment rings rotate smoothly without looseness, which matters for video work where gradual ND transitions between shots require precise, repeatable dial movement. A filter that rotates with inconsistent resistance or has a loose frame introduces handling errors that glass quality alone won’t fix.

Frequently Asked Questions

What is the difference between a 72mm and 82mm ND filter , can I use 82mm filters on a 72mm lens?

An 82mm filter is built for lenses with an 82mm filter thread and will not thread directly onto a 72mm lens without an adapter ring. Step-up rings , which adapt a smaller thread to accept a larger filter , allow you to use an 82mm filter on a 72mm lens, though the filter will extend beyond the lens barrel and may increase vignetting risk on wide focal lengths.

What does “No X Cross” mean on a variable ND filter?

X-cross (also called the cross-pattern artifact) occurs on variable ND filters when the two polarizer elements are rotated near or past their maximum range. The polarizer planes create an interference pattern that appears as a visible dark X or asterisk across the frame. “No X Cross” filters solve this by limiting the rotation range so the artifact zone is never reached , the trade-off is a narrower maximum ND value, typically capping at ND32 rather than ND400.

Which filter in this lineup is best for video shooting?

The K&F Concept 82mm Variable ND2-ND32 No X Cross is the strongest option for video work. Maintaining the 180-degree shutter rule typically requires ND4 to ND32 in outdoor conditions, which this filter covers entirely , and the elimination of X-cross artifacts means every position on the dial is usable without managing an unsafe rotation zone. Reliable, clean output across the full range matters more on video than the ability to reach ND400.

Do combination ND-CPL filters work as well as using a separate ND and CPL stacked together?

Optically, separate high-quality ND and CPL filters stacked together can outperform a combination filter , but the combination option eliminates the stacking penalty: fewer glass elements in the light path, no additional vignetting from the extra frame thickness, and one rotation ring to manage instead of two. For photographers prioritizing kit simplicity and outdoor portability over maximum optical purity, the combination filters , particularly the Nano-X PRO option , are a practical and optically competitive choice.

How do I clean a multi-coated ND filter without damaging the coatings?

Use a clean, dry microfiber cloth for dust and dry particles , drag across the glass gently rather than applying circular pressure. For smudges and fingerprints, breathe lightly on the glass to add minimal moisture, then wipe with a clean microfiber cloth in a single direction. Avoid lens tissues with cleaning solvents unless they are specifically labeled safe for coated optics, as aggressive solvents can damage multi-layer coatings over time. Waterproof-treated filters tolerate light moisture cleaning better than untreated alternatives.
