For a flexible camera setup, the K&F CONCEPT 67mm Variable ND2-400 is my best overall pick because its broad adjustment range suits changing light without swapping filters. The Neewer 67mm Variable ND + CPL + UV Kit is a stronger fit if you want three filter types, while K&F’s DJI Mini 5 Pro set is purpose-built for drone users. The main tradeoffs are adjustment range versus image artifacts, and a bundled kit versus a filter matched to one lens or camera. Read on for how these six options differ and which one fits your shooting.

Key Takeaways
- The standard 67mm variable filters offer the broadest camera-use flexibility: K&F’s ND2-400 options and Neewer’s ND2-ND400 cover a wide range of light reduction, but users must watch for uneven darkening near the strongest settings.
- K&F’s ultra-slim ND2-ND400 is the more deliberate pick for compact lens setups: its slim build sets it apart from the standard K&F 67mm filter, though buyers should still check lens compatibility and accessory clearance.
- Neewer’s three-pack prioritizes kit breadth over a single specialized filter: it combines variable ND, CPL, and UV filters, while its extra components mean more items to store and swap.
- The 77mm K&F ND4-64 combines density adjustment with a polarizing effect: that may suit reflective scenes, but it is less straightforward than a separate ND filter and CPL when independent control matters.
- The DJI Mini 5 Pro set is the only drone-specific option: its ND2-32 and ND32-512 filters target aerial exposure needs, so it is a poor fit for buyers seeking a general camera-lens filter.

More Details on Our Top Picks
K&F CONCEPT 67mm Variable ND2-400 Lens Filter
I’d choose this K&F CONCEPT when one 67mm filter needs to cover a broad range of daylight exposure changes. Its 1–9-stop adjustment and full 360-degree rotation give still photographers and video shooters room to adapt without swapping fixed ND filters. Compared with the K&F CONCEPT 67mm ND2-ND400 Ultra Slim, this version lists eight multilayer coatings rather than 18, so the other model has the stronger stated coating specification. Both share a slim 7.4 mm frame and the same high-strength caveat: at maximum settings, some lenses may show a cross-pattern artifact. I also wouldn’t treat it as weather-ready; it is not water resistant. The 100 g weight is reasonable for a standard lens filter, but the required 72 mm lens cap complicates replacing a lost cap.
Pros:- Covers 1–9 stops of light reduction in one filter
- 360-degree rotation allows fine exposure adjustment
- AGC optical glass has eight multilayer coatings
- Slim 7.4 mm aluminum frame has a grip-enhancing CNC pattern
Cons:- May show a cross-pattern effect at maximum settings with some lenses
- Requires a 72 mm lens cap despite fitting 67mm lens threads
- Not water resistant
Best for: Photographers with a 67mm-thread lens who want one rotating filter for a wide range of outdoor exposure adjustments.
Not ideal for: Shooters who regularly work at maximum ND strength on wide-angle lenses, need water resistance, or want to use a standard 67mm lens cap.
- Filter size:67 mm
- Light reduction:1–9 stops
- Rotation:360 degrees
- Glass:AGC optical glass
- Coatings:8 multilayer coatings
- Frame thickness:7.4 mm
- Weight:100 g
- Included accessory:Microfiber cleaning cloth
- Water resistance:Not water resistant
Our verdict“Choose this for broad variable-ND control on a 67mm lens, but favor the 18-coating K&F CONCEPT Ultra Slim if coating count is your priority.”
K&F CONCEPT 67mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) Ultra Slim
This is my pick among the standard 67mm variable-ND options when the stated coating package is the deciding factor. It spans 1–9 stops in a slim 7.4 mm frame, while its 18 multilayer coatings exceed the eight listed for the K&F CONCEPT 67mm Variable ND2-400 Lens Filter. That difference may appeal to photographers concerned about reflections and glare, though the product data alone does not establish a visible image-quality advantage in every situation. Like its sibling, this filter can produce an X-shaped cross near maximum strength, so I’d leave some range in reserve for demanding wide-angle shots. Its usefulness is also limited to lenses with 67mm threads, and it needs a 72mm lens cap. Pick it over the DJI Mini 5 Pro kit only if you need a filter for a standard camera lens.
Pros:- Adjustable 1–9-stop range suits changing daylight
- 18 multilayer coatings are the highest stated coating count among the standard 67mm single-filter picks here
- Slim 7.4 mm design is suited to a low-profile setup
- Secure rotation supports adjustment without changing filters
Cons:- Can show an X-shaped cross at high settings
- Only fits 67mm lens threads
- Requires a 72mm lens cap
Best for: Still photographers and videographers with 67mm-thread lenses who want a slim variable ND and prioritize a higher stated coating count.
Not ideal for: Drone owners, users with other lens thread sizes, or anyone who needs reliable maximum-strength ND on a lens prone to cross-pattern artifacts.
- Filter size:67 mm
- Light reduction:1–9 stops
- Glass:AGC optical glass
- Coatings:18 multilayer coatings
- Thickness:7.4 mm
- Compatibility:67mm lens threads
- Lens cap requirement:72 mm
Our verdict“Choose this over the eight-coating K&F 67mm sibling if the higher stated coating count matters more than a basic single-filter setup.”
K&F CONCEPT Variable ND Filter Set for DJI Mini 5 Pro, ND2-32 & ND32-512
Unlike the screw-on camera filters elsewhere in this roundup, this K&F set is made specifically for the DJI Mini 5 Pro. It splits its adjustment into two filters: ND2-32 for 1–5 stops and ND32-512 for 5–9 stops. That division gives drone users a choice between moderate and stronger light reduction without carrying a full-size 67mm filter, and the 2.78 g weight is designed not to burden gimbal operation. Multi-layer coatings are listed as waterproof, scratch-resistant, dustproof, and oil-proof. The tradeoff is strict compatibility: unlike the 77mm K&F ND/CPL filter or the Neewer 67mm kit, this set cannot serve a camera lens. Buyers also need to understand how ND strength affects exposure; the two-filter setup isn’t a substitute for a general-purpose variable filter.
Pros:- Designed specifically for DJI Mini 5 Pro fit
- Two filters cover 1–9 stops across separate ranges
- At 2.78 g, the set is designed to avoid affecting gimbal operation
- Coatings are described as waterproof, scratch-resistant, dustproof, and oil-proof
Cons:- Limited to DJI Mini 5 Pro use
- Two separate ranges require swapping filters when lighting calls for a different strength
- Getting the intended exposure requires familiarity with ND adjustment
Best for: DJI Mini 5 Pro pilots filming in varied daylight who want lightweight ND options made for that drone.
Not ideal for: Camera owners seeking a filter for interchangeable lenses, or pilots who want a single general-purpose filter rather than two separate ND ranges.
- Compatibility:DJI Mini 5 Pro
- Filter ranges:ND2-32 and ND32-512
- Light reduction:1–5 stops and 5–9 stops
- Weight:2.78 g
- Glass:Imported AGC optical glass
- Coatings:Multi-layer coatings
- Coating protection:Waterproof, scratch-resistant, dustproof, and oil-proof
Our verdict“Choose this set if you fly a DJI Mini 5 Pro and need drone-specific ND coverage; skip it for any camera lens system.”
K&F CONCEPT 77mm Variable ND4-64 Lens Filter & Polarizing Effect 2-in-1
This 77mm filter suits photographers who want to adjust exposure and reduce reflections with one front-mounted accessory. Its 2–6-stop ND range is narrower than the 1–9 stops offered by the K&F CONCEPT 67mm filters and Neewer’s 67mm kit, but that makes it a more focused choice for moderate exposure changes rather than maximum light reduction. The integrated CPL effect can cut glare from non-metallic surfaces and enhance color contrast, an option the other listed variable-ND filters don’t provide. K&F says its design avoids the common X-cross issue, though users should still check results across their lens range. The aluminum frame has a lever for adjustment, and the filter requires an 82mm lens cap. Its larger thread also rules it out for 67mm lenses without a suitable step-up arrangement.
Pros:- Combines variable ND and polarizing effects in one filter
- 2–6-stop range is suited to moderate exposure adjustment
- 28 multilayer coatings are listed, with waterproof and scratch-resistant protection
- Lever and marked stops make rotation easier to set
Cons:- Stops at 6 stops, below the 9-stop reach of several alternatives
- Requires an 82mm lens cap
- 77mm thread limits direct fit to compatible lenses
Best for: Landscape and outdoor photographers with 77mm lenses who want moderate ND control plus glare reduction from non-metallic surfaces.
Not ideal for: Users who need 7–9 stops of reduction, own only 67mm-thread lenses, or prefer a separate CPL for independent adjustment.
- Filter size:77 mm
- Light reduction:2–6 stops
- Filter type:Variable ND with CPL effect
- Glass:Imported AGC optical glass
- Coatings:28 multilayer coatings
- Frame material:Aluminum alloy
- Lens cap requirement:82 mm
- Frame adjustment:Lever with marked stops
Our verdict“Choose this 77mm option if glare control matters alongside moderate ND adjustment, but pick a 1–9-stop filter for stronger light reduction.”
Neewer 67mm Variable ND + CPL + UV Filter Kit (3 Pack)
Neewer’s kit is the broadest package here for a 67mm lens: it includes UV, CPL, and variable ND filters, so buyers get separate tools for lens protection, glare reduction, and exposure control. The variable ND covers 1–9 stops, matching the range of the K&F CONCEPT 67mm filters, while the K&F 77mm 2-in-1 combines ND and CPL effects in a single filter instead. I’d favor Neewer for someone building a basic filter set, not for a photographer seeking the simplest setup. Separate filters add flexibility, but they also mean more pieces and thread sizes to track. The kit’s front thread is 72mm, so accessories and lens-cap fit need attention. Although its slim aluminum frame is described as helping prevent wide-angle vignetting, the ND still needs careful adjustment for the intended result.
Pros:- Includes UV, CPL, and variable ND filters
- Variable ND covers 1–9 stops
- Multicoated glass is described as resisting water, fingerprints, and scratches
- Includes a protective case and lens caps for transport and storage
Cons:- Requires a 67mm lens thread and uses 72mm front accessories
- Multiple filter types and thread sizes can complicate setup
- Variable ND needs careful adjustment to achieve the intended exposure
Best for: Newer photographers and videographers with 67mm lenses who want separate UV, CPL, and variable-ND filters in one kit.
Not ideal for: Minimalist shooters who want one combined filter, or buyers who don’t want to manage 67mm and 72mm thread compatibility.
- Filter size:67 mm
- Filter types:UV, CPL, and variable ND
- Variable ND range:ND2-400, 1–9 stops
- Filter material:Multicoated glass
- Frame material:Aluminum alloy
- Front thread:72 mm
- Included accessories:Protective case and lens caps
Our verdict“Choose this kit if you want three distinct filter functions for a 67mm lens, but pick the K&F 77mm 2-in-1 for a simpler ND-and-polarizer combination.”
Neewer 67mm Variable ND Filter ND2-ND400 (1-9 Stops), Neutral Density Filter with Multi-Coatings
The Neewer 67mm Variable ND is a practical single-filter choice for photographers who want broad exposure adjustment without carrying a set of fixed NDs. Its ND2–ND400 range covers 1–9 stops, while the coated optical glass is described as resistant to water, oil, and scratches—useful for outdoor work where fingerprints or light moisture are harder to avoid. Compared with the Neewer 67mm Variable ND + CPL + UV Filter Kit, this option focuses on one variable filter rather than adding three filter types; that keeps the choice simpler, but gives up the kit’s extras. The 9.5mm slim frame may help limit vignetting, though a dark cross pattern can appear with some lens and setting combinations. Its range also stops short of the ND2000 strength needed for some very long exposures.
Pros:- Adjustable ND2–ND400 range provides 1–9 stops of light reduction.
- Multi-coated optical glass is designed to reduce flare and ghosting.
- Water- and scratch-resistant coatings suit frequent outdoor handling.
- Slim 9.5mm metal frame is intended to reduce vignetting.
Cons:- A dark cross pattern may appear with certain lenses or settings.
- Performance varies with shooting conditions and lens combinations.
- ND400 does not provide the very strong reduction available from ND2000 filters.
Best for: Outdoor photographers with 67mm lenses who want a coated, adjustable ND filter for general exposure control and prefer one filter over a multi-filter kit.
Not ideal for: Photographers who need extreme long-exposure reduction, want multiple filter types in one purchase, or use lenses without 67mm filter threads.
- Filter diameter:67mm
- ND range:ND2–ND400
- Light reduction:1–9 stops
- Material:Optical glass with nano coatings
- Frame thickness:9.5mm
- Coating properties:Designed to reduce flare and ghosting; water- and scratch-resistant
- Lens-cap compatibility:Compatible with 72mm lens caps
Our verdict“Choose this Neewer if you want a coated 67mm variable ND for everyday outdoor exposure control, but skip it for extreme long exposures or a multi-filter kit.”
How We Picked
I ranked these sets by how well their design matches a clear buyer need: a versatile variable filter for a camera lens, a thinner profile, an all-in-one filter kit, a combined ND and polarizing effect, or filters made for a specific drone. I compared stated density ranges, filter size or device fit, included filter types, coatings where specified, and the practical compromises those choices create. A broad range can reduce filter changes, but it does not automatically make maximum settings the best choice for every scene.
The ranking favors useful coverage and a clear fit over a longer feature list. The general-purpose 67mm options lead because their ND2-to-ND400 ranges suit a wide range of camera work; the slim K&F version earns distinction for buyers who value a low-profile setup. The Neewer kit, combined ND/CPL model, and DJI set rank lower for general use because each is more specialized, though one of them may be the better match for its intended buyer. I also treated exact lens diameter and camera compatibility as essential checks rather than assuming any filter will fit every setup.

Factors to Consider When Choosing Nd Filter Sets Variable
Variable ND filters can make exposure adjustments faster, but the right set depends on more than its maximum density. I would match the filter to the camera, lens, and way you shoot before choosing a broad range or a bundle. These checks help prevent fit problems and avoid paying for features that do not suit your footage or stills.
Match the filter diameter to your lens
Check the filter thread symbol on each lens rather than relying on the camera body or lens name. A 67mm filter will not screw onto a 77mm lens without a step-up ring, and a ring can affect how other accessories fit. If you use several lenses, buying for the largest front thread and using step-up rings may be more economical than buying a filter for each lens. That approach adds parts to carry and can make a compact setup less convenient. Avoid choosing a filter diameter based only on a lens you may replace soon.
Choose a usable density range, not just the biggest number
A wider range can cover more lighting conditions without filter swaps, which helps when filming outdoors or moving between shade and sun. But variable ND filters can show uneven dark patches or cross-pattern artifacts near the strongest setting, especially across wide views or bright skies. For critical footage, leave room below the maximum and check the image at the settings you expect to use. A narrower range may be easier to control if your exposure needs are consistent. Think about your usual shutter speed and light before making maximum density the deciding spec.
Decide whether combining a CPL is worth the compromise
A polarizer can reduce reflections from surfaces such as water and glass, while an ND filter reduces incoming light. A combined filter may reduce the number of accessories you carry, but changing one effect can influence the other, making independent adjustment less direct. Polarization also varies with the angle to the sun, so the effect may look uneven across a wide landscape. If reflection control is central to your work, separate filters offer more control. Choose a combined design when convenience matters more than adjusting each effect independently.
Check how the filter will affect your lens setup
Filter thickness can matter when shooting with a wide-angle lens, stacking accessories, or using a lens hood. A slim design can help reduce clearance issues, but it does not guarantee that every lens combination will avoid vignetting. Check whether the filter has front threads if you plan to attach a cap or another accessory. Stacking filters can add reflections and make corner shading more likely. If you rarely use accessories, a standard profile may be perfectly practical; if you do, treat thickness and threading as part of the fit check.
Treat drone filters as a separate purchase category
Drone filters are made for a particular camera and gimbal, not for interchangeable camera lenses. Their fit and weight can affect how securely they mount, so a lens-thread measurement is not the right compatibility test. Check that the set names your exact drone model and that each filter range suits the exposure conditions you encounter. A drone-specific set offers little value if you also need filters for a mirrorless camera. Buyers who use both systems may be better served by treating the drone and camera as separate filter kits.
Choose a kit based on how you work, not the item count
A bundle with ND, CPL, and UV filters can cover different tasks, but included pieces only add value when you will use them. More filters mean more storage, cleaning, and opportunities to leave the wrong one on the lens. Before paying for a multi-filter set, identify which effects you actually need and whether each can be adjusted independently. A single variable ND may be a simpler everyday choice for video exposure control. A kit makes more sense when you want to build a basic filter collection at once and accept the extra handling.
Frequently Asked Questions
Can I use a 67mm variable ND filter on a lens with a different thread size?
Not directly: the filter diameter must match the lens thread, or you need a compatible step-up or step-down ring. A step-up ring lets a smaller lens accept a larger filter, which can help you share one filter across lenses. A step-down ring can block the frame edges, particularly on wide-angle lenses, so it is usually the riskier direction. Check the thread size printed on the lens or its cap before ordering. Also confirm that the added ring leaves enough clearance for a hood or other accessories.
Is ND2-400 a better choice than ND4-64 for video?
It depends on how much light changes during your shoots and how often you want to swap filters. ND2-400 gives a broader adjustment span, which can be useful outdoors, while ND4-64 covers a more limited range and may be sufficient in steadier conditions. A broad range does not mean every setting will look clean in every scene; check for uneven darkening near the strongest end. If your work needs a consistent look across wide shots, leaving some range unused can be preferable. Choose based on your typical light, not the biggest stated range alone.
Should I buy a variable ND with a built-in CPL or separate filters?
A combined ND and CPL can save space and reduce the number of accessories to carry, which suits travel or a minimal kit. Separate filters give you more independent control over exposure reduction and reflection handling. That matters when you want neutral density without changing polarization, or when the sun angle makes polarization uneven across the frame. The K&F 77mm combination is the specialized option in this roundup; it is not the simplest choice for every scene. Pick a combination for convenience, and separate filters when precise control is your priority.
Are camera variable ND filters suitable for the DJI Mini 5 Pro?
Camera-lens filters are not a substitute for filters designed to fit the DJI Mini 5 Pro. Drone filters need the correct mount and must suit the camera and gimbal, so a 67mm or 77mm lens filter will not attach as intended. The K&F drone set in this roundup is specifically listed for the Mini 5 Pro and includes two density ranges. Check the product’s stated model compatibility before buying, since a similar-looking drone may use a different filter fit. If you also shoot with a regular camera, plan for a separate lens-filter system.
Is a three-filter kit a better first purchase than one variable ND?
A kit can be a useful start if you have clear uses for its ND, CPL, and UV filters and want to keep them together. It is not automatically the better first purchase: extra pieces add storage and handling, and you may need only exposure control. A single variable ND is simpler if video is your main use and you know the correct lens diameter. Before choosing a bundle, identify the scenes where each filter will help. If you cannot name a job for every included piece, start with the filter that meets your main need.
Conclusion
For most camera users, I would start with the K&F CONCEPT 67mm Variable ND2-400 as the best overall pick: it pairs a broad range with straightforward general-purpose use. The Neewer 67mm three-pack is my best value-style choice for buyers who will use ND, CPL, and UV filters, while the K&F ultra-slim ND2-ND400 is the better fit for a low-profile 67mm setup. Beginners who want one simple camera filter can start with either standard 67mm ND2-400 option after checking their lens thread; the Neewer kit suits beginners who want multiple filter types. For a specific need, choose the K&F 77mm ND4-64 with polarizing effect for a combined setup, or the K&F DJI Mini 5 Pro set for that drone. Match the diameter or device first, then choose the range and bundle that fit how you shoot.
