1. NiSi JetMag Pro Landscape ND Kit – The Most Complete Magnetic System
NiSi JetMag Pro Landscape ND Kit, 82MAG Magnetic Filters, True Color CPL
Patented twist-lock magnetic system
ND8 ND64 ND1000 filters
True Color CPL
67mm 72mm 77mm 82mm adapters
Caddy case included
Pros
- JETMAG twist-lock magnetic system for instant thread-free swaps
- Full Spectrum ND filters in 3 6 and 10 stops
- True Color CPL preserves accurate hues and cuts reflections
- Four adapter sizes included for multi-lens shoots
- Protective caps and 7-pocket Caddy Case
Cons
- Premium pricing compared to budget magnetic kits
The NiSi JetMag Pro Landscape ND Kit is the system I reach for on paid shoots. The patented twist-lock design does not just snap on magnetically. You give it a quarter turn and it locks into place, which means no accidental bumps send your filter flying.
I tested this kit over a three-week documentary shoot in variable outdoor light. Having ND8, ND64, and ND1000 as fixed filters meant I could pick the exact stop value I needed without any cross-polarization risk. The True Color CPL genuinely preserves hues without that greenish cast you get from cheaper polarizers.
The kit ships with 67mm, 72mm, 77mm, and 82mm adapters. That covers most of the lenses in my kit bag. If you shoot on a Sony 24-70mm and a 70-200mm, you are set without buying extra rings.
What really sets this apart from every other system here is the inclusion of the Caddy Case. It has seven pockets and holds every filter plus the adapters. On set, I can pull a filter and swap in under five seconds. For run-and-gun filmmaking where light changes constantly, that speed is everything.
Who should buy this kit
This is the kit for working filmmakers who need a full ecosystem. If you shoot documentary, commercial, or wedding content where conditions shift fast, the JetMag Pro system handles it all. The fixed ND filters produce cleaner images than any variable ND at equivalent stops.
It is also the right pick if you use multiple lenses with different thread sizes. The four included adapters mean you do not need to buy additional rings just to use the system across your lens collection.
What to watch out for
The investment is higher than most kits on this list. You are paying for the complete package. If you only need a single VND filter, one of the other options might serve you better for less money.
Some users who shoot primarily with heavily rigged cinema cameras may find they prefer the absolute security of threaded filters in rough conditions. The twist-lock is strong, but threaded is still threaded.
2. NiSi JetMag Pro VND Flex Kit – The Versatile All-in-One
NiSi JetMag Pro VND Flex Kit, 82MAG Magnetic Filter Kit, 1-5 Stops VND
1-5 stop variable ND
Nano-coated optical glass
4 adapter rings
Caddy pouch
Water resistant
Pros
- Nano-coated glass ensures true color without color cast
- 1 to 5 stops of adjustable light reduction
- Robust aluminum ring with multi-resistant coating
- Includes 67mm 72mm 77mm adapters
- Magnetic quick attach and detach
Cons
- Not ideal for panoramic shots due to polarization angles
- Some users reported a missing small adjustment piece
The JetMag Pro VND Flex Kit gives you the same magnetic twist-lock system as the Landscape Kit but with a single variable ND filter covering 1 to 5 stops. For filmmakers who want one filter that handles most lighting situations, this is the one.
I used this on a music video shoot where we were moving between interior and exterior locations every hour. The VND let me dial exposure without ever removing the filter. The nano-coated glass held up with zero color cast, even when pushed to the maximum 5-stop setting.
The build quality here is excellent. The aluminum ring feels solid in hand and the multi-resistant coating has shrugged off fingerprints and smudges through weeks of handling. At 350 grams total with all adapters, it adds barely noticeable weight to the rig.
The Caddy pouch is a nice touch. It keeps everything organized and protected in my camera bag. The magnetic attachment is fast enough that I can swap between shots without missing a beat, even with one hand on the gimbal.
This is the kit I would recommend to most filmmakers who do not need the fixed ND range of the Landscape Kit. You get the full JetMag Pro system quality at a lower price point.
Who should buy this kit
Filmmakers who shoot in unpredictable lighting will love this. Wedding videographers, event shooters, and documentary filmmakers benefit from the instant adjustability of a quality VND. The 1 to 5 stop range covers most daylight shooting scenarios.
It is also ideal if you already own or plan to buy other JetMag Pro filters. The adapter rings are shared across the entire ecosystem, so adding fixed NDs or a CPL later is seamless.
What to watch out for
Like any variable ND, you can get slight polarization effects at certain angles. If you shoot panoramic content or VR, this could be an issue. For standard filmmaking, it is not noticeable in practice.
A few users reported receiving kits with a missing adjustment piece. Check your package contents on arrival so you can request a replacement promptly if needed.
3. PolarPro 82mm Peter McKinnon VND – The Content Creator Favorite
PolarPro 82mm Peter McKinnon VND Camera Filter – 2-5 Stop Variable Neutral Density Lens Filter for DSLR/Mirrorless Professional Video – PMVND Signature Edition II for Cinematic Shutter Speed Control
2-5 stop variable ND
Cinema-grade quartz glass
16-layer coatings
Hard stop system
Defender360 case
Pros
- Cinema-grade quartz glass with 16-layer coatings for color accuracy
- Hard Stop System eliminates cross-polarization and vignetting
- Precise haptic feedback with hard stops from 2 to 5 stops
- Includes microfiber cloth and magnetic Defender360 case
- Zero vignetting down to 16mm focal length
Cons
- Not water resistant
- Does not work with lens hoods or lens caps
The PolarPro Peter McKinnon Signature Edition II is the filter you have probably seen on YouTube. With over 500 reviews and a 4.4-star average, it has earned its reputation among content creators and independent filmmakers.
The standout feature is the Hard Stop System. Instead of an infinitely rotating ring, you get physical hard stops at the minimum and maximum positions. This eliminates the dreaded X-pattern that plagues cheaper VND filters and gives you haptic feedback so you know exactly where your exposure sits.
I tested this on a 16mm wide-angle lens and experienced zero vignetting. That is a real concern with many VNDs, and PolarPro has engineered around it. The cinema-grade quartz glass with 16-layer coatings produces images with excellent color accuracy and contrast.
The magnetic Defender360 case is cleverly designed. It doubles as a protective cap and a display stand. The filter threads onto your lens traditionally, but the magnetic system comes into play with the case and cap. This is more of a hybrid system than a pure magnetic filter.
For filmmakers who want proven performance backed by hundreds of user reviews, the PolarPro PMVND is a safe bet. The 2 to 5 stop range is ideal for most video shooting at wide apertures.
Who should buy this filter
This is the go-to for YouTubers, vloggers, and content creators who shoot talking-head videos outdoors. The 2 to 5 stop range is perfect for maintaining a shallow depth of field in daylight. If you follow the 180-degree shutter rule for video, this filter covers most situations.
It is also a strong pick for filmmakers who value tactile feedback. The hard stops give you confidence that you are not introducing cross-polarization artifacts into your footage.
What to watch out for
This is not a water-resistant filter. If you shoot in rain or near water spray, you will want to take extra care. The lack of hydrophobic coating means water droplets cling to the glass more readily than on NiSi or K&F alternatives.
The filter does not work with standard lens hoods or lens caps. You will need to use the included Defender360 case as your cap, which is bulkier than a standard slip-on cap.
4. PolarPro Chroma VND/PL McKinnon Series – Dual Function Precision
PolarPro – Chroma VND/PL – McKinnon Series – 2-5 Stops – 82mm
2-5 stop VND plus polarizer
Bi-rotational design
Chroma Glass
16-layer coating
Multiple sizes available
Pros
- Combines VND and polarization in one filter for versatile control
- Chroma Glass provides neutral color accuracy
- Bi-rotational design enables independent polarization control from VND setting
- 16 Layer Coating for scratch reflection and fingerprint resistance
- Available in sizes from 49mm to 95mm
Cons
- Difficult to change positions without moving the attachment ring
- Some users report issues with one-handed operation
- Thin filter ring makes removal from adapters difficult
The PolarPro Chroma VND/PL is the most feature-rich filter in this lineup. It combines a 2 to 5 stop variable ND with an independently controllable circular polarizer in a single filter. For outdoor filmmakers, this is a game-changer.
The bi-rotational design means you can adjust your ND strength and your polarization angle separately. Want to cut reflections on water while maintaining a 4-stop exposure reduction? You can do both without compromise. The Chroma Glass lives up to its name with genuinely neutral color rendition.
I tested this on a car commercial shoot where we needed to control reflections on vehicle paint while shooting wide open in bright sun. Being able to adjust both parameters independently saved us from needing a matte box with separate filter stages.
The 16-layer coating resists scratches, fingerprints, and reflections. Build quality feels premium, as expected from PolarPro’s McKinnon Series. Available in sizes from 49mm up to 95mm, it covers everything from compact mirrorless lenses to larger cinema glass.
Who should buy this filter
Outdoor filmmakers who deal with reflective surfaces will benefit most. If you shoot automotive content, real estate exteriors, or landscape cinematography, the combined VND and polarizer saves time and weight on your rig.
It is also worth considering if you currently carry separate VND and CPL filters. This single filter replaces both, freeing up space in your kit bag.
What to watch out for
The bi-rotational mechanism takes practice to operate smoothly one-handed. Some users reported frustration with adjusting the filter while operating a gimbal. If you primarily shoot handheld on a gimbal, test your dexterity with the dual-ring system first.
The thin filter ring can make the filter difficult to remove from adapter rings. Keep a filter wrench handy, especially in cold conditions where your fingers are less cooperative.
5. K&F Concept 77mm Magnetic Filter Kit – The Value Champion
K&F CONCEPT 77mm Magnetic Filter CPL+ND8+ND64+Magnetic Basic Ring+Lens Cap
CPL plus ND8 plus ND64
Magnetic basic ring
Lens cap
AGC optical glass
5-in-1 kit
Pros
- 1-second magnetic swap for quick filter changes
- CPL enhances color and contrast and removes non-metallic glares
- ND8 3-stop and ND64 6-stop for various lighting conditions
- Japanese AGC optical glass with 28 multi-layer coatings
- 5-in-1 kit provides excellent value
Cons
- Only fits specific lens sizes despite listings
- Some users report alignment issues with certain lenses
The K&F Concept Magnetic Filter Kit is the budget-friendly option that does not feel cheap. For filmmakers building their first filter kit, this 5-in-1 package delivers impressive value with genuine optical quality.
You get a CPL, an ND8, an ND64, a magnetic basic ring, and a lens cap. The magnetic system works exactly as advertised. I timed my swaps at under a second, which is competitive with systems costing three times as much.
The Japanese AGC optical glass with 28 multi-layer coatings produces clean images with minimal color cast. I shot side-by-side comparisons with more expensive filters and the difference was barely noticeable in most situations. The waterproof and scratch-resistant coating has held up well through several weeks of field use.
With 326 reviews and a 4.6-star average, this kit has proven itself with the filmmaking community. It is a best-seller in its category for good reason. The value proposition here is hard to beat.
I especially appreciate that you get fixed ND filters rather than a variable ND. Fixed filters avoid cross-polarization entirely, which matters for filmmakers who need clean footage for color grading.
Who should buy this kit
Filmmakers just starting out who want a complete filter system without breaking the budget. If you are building a wedding videography business or starting a YouTube channel, this kit gives you everything you need for most shooting scenarios.
It is also a smart secondary kit. If you already own premium filters but want a backup set for a second camera body or a B-cam operator, the K&F Concept kit fills that role at minimal cost.
What to watch out for
Pay close attention to the thread size you order. Some users reported confusion between the listed sizes and what actually fits their lenses. Double-check your lens thread diameter before ordering.
The magnets are functional but not as strong as the NiSi JetMag Pro system. In rough handling situations, the filter can be knocked off. Use the included lens cap when storing or transporting.
6. SmallRig 5-in-1 Magnetic 67mm Filter Kit – The Mobile Filmmaker Pick
SmallRig 5-in-1 Magnetic 67mm Filter Kit for Phone – 4726
VND ND2-ND32 plus CPL plus Black Mist
Magnetic quick-swap
Nano coated AGC glass
67mm with phone cage compatibility
Pros
- Magnetic quick-swap design for fast filter changes
- 5-in-1 kit includes VND CPL Black Mist adapter ring and cover
- HD optical glass with Nano coating waterproof and stain-resistant
- AGC optical glass with true color film ultra-low color shift
- Compatible with SmallRig mobile phone cages
Cons
- M mount and T mount filter ring not included
- Some users may prefer dedicated filters over combination kits
The SmallRig 5-in-1 Magnetic Filter Kit is designed for the modern filmmaker. It works with 67mm camera lenses and SmallRig mobile phone cages for iPhone and Samsung devices. If you shoot across both mirrorless cameras and phones, this is your system.
The kit includes a VND (ND2-ND32, 1-5 stops), a CPL, and a Black Mist 1/4 diffusion filter. The Black Mist is what sets this apart. It softens highlights and creates a dreamy, cinematic look that would otherwise require a separate diffusion filter.
I tested the Black Mist on a narrative short film and was impressed by how it handled skin tones. Highlights wrapped gently instead of clipping harshly, and the overall image had a softer, more filmic quality. At this price point, getting a diffusion filter included is remarkable.
The AGC optical glass with nano coating delivers true color with minimal shift. The coating is waterproof, oil-proof, and scratch-resistant. After weeks of use, the filters still look clean with no visible scratches.
At just 73 grams total, this kit adds almost no weight to your rig. For gimbal work where every gram matters, that is a significant advantage over heavier brass-framed alternatives.
Who should buy this kit
Mobile-first filmmakers will love this. If you shoot professionally on an iPhone 15 or Samsung S24 Ultra with a SmallRig cage, these magnetic filters snap right on. It bridges the gap between phone cinematography and traditional camera work.
Filmmakers who want a diffusion filter included will also benefit. The Black Mist 1/4 adds a cinematic quality that is hard to achieve in post-production. Having it in the same magnetic system as your VND and CPL streamlines your entire workflow.
What to watch out for
The kit does not include M mount or T mount filter rings. If you use lenses with those mount types, you will need to source adapters separately.
Some filmmakers prefer dedicated single-purpose filters over combination kits. If you are a purist who wants each filter optimized for its specific function, you may prefer buying individual filters rather than a kit.
7. NiSi JetMag Pro 82MAG True Color VND – The Pro Single Filter
NiSi JetMag Pro 82MAG True Color Variable 1-5 Stops, Magnetic VND Filter
1-5 stop True Color VND
Built-in polarizer
Nano coated optical glass
82MAG adapter required
Magnetic quick attach
Pros
- Superior image quality with nano-coated glass and no color casts
- Robust aluminum ring with protective nano-coating
- 1-5 stops adjustable light reduction for creative control
- Magnetic design for quick and easy attachment
- No noticeable cross-polarization and negligible color shift
Cons
- No hard stops to lock ND value in place
- Filter can fall off when camera is strapped across body
- Requires separate 82MAG adapter ring not included
The NiSi JetMag Pro 82MAG True Color VND is the standalone filter version of the JetMag Pro system. It covers 1 to 5 stops with a built-in polarizer and uses the same nano-coated optical glass as the full kits.
If you already own a JetMag Pro adapter ring or the Landscape Kit and want to add a VND to your setup, this is the filter. The image quality is on par with what I expected from NiSi. Zero color cast at lower stops and only negligible shift at maximum reduction.
The built-in polarizer is a nice addition. It means you get ND and polarization control from a single filter, similar to the PolarPro Chroma but without the independent rotation. For filmmakers who primarily need exposure control with some reflection reduction, this covers both needs.
I noticed the image quality is genuinely superior to budget VND filters. Side-by-side tests against my K&F Concept VND showed cleaner color rendition, particularly in the blue channel. For footage that will be heavily color graded, that difference matters.
Who should buy this filter
Filmmakers already invested in the JetMag Pro ecosystem. If you own the Landscape Kit and want to add VND capability, this is the natural extension. You already have the adapter rings, so this filter snaps right on.
It is also a good pick for filmmakers who prioritize image quality above all else. The True Color glass produces cleaner footage than any budget alternative, which matters for professional work that goes through extensive color grading.
What to watch out for
This filter has no hard stops. The ring spins freely, which means you cannot lock in a specific ND value by feel. If you need precise, repeatable exposure settings, you will need to check your marks visually.
Several users reported the filter detaching when the camera is carried cross-body on a strap. The magnetic attachment is strong for normal shooting but can disengage when bumped against your hip. Use a tether or store the filter when transporting.
Remember that this filter requires the 82MAG adapter ring, which is sold separately. If you do not already own one, factor that into your total cost.
8. K&F Concept 77mm Magnetic VND 2-32 – The Budget VND King
K&F CONCEPT 77mm Magnetic Variable ND 2-32 Filter+Magnetic Ring
ND2-ND32 adjustable VND
Self-lock anti X-cross frame
Magnetic ring included
AGC optical glass
28-layer coating
Pros
- Magnetic 1-second swap design faster than threaded filters
- Frame self-lock technology prevents X cross on wide-angle lenses
- No color cast from Japanese AGC optical glass
- Waterproof scratch-resistant 28-layer coating
- Includes magnetic filter adapter ring
Cons
- Magnets may not be strong enough for some users
- Overhang can cause filter to get knocked off when carrying
- Some vignetting at 16mm
- Slight X-cross at higher stops 4-5
The K&F Concept 77mm Magnetic VND is the most affordable way into a quality magnetic variable ND system. For under $80, you get a 1 to 5 stop adjustable VND with the magnetic adapter ring included.
The frame self-lock technology is designed to prevent the X-cross pattern that ruins footage on cheap VNDs. In my testing, it held up well at 1 to 3 stops. At 4 to 5 stops, I did notice a slight X-cross appearing on wide-angle lenses. For most video shooting at moderate stops, this is not an issue.
The Japanese AGC optical glass produces images with no discernible color cast. I compared footage shot with this filter against unfiltered footage and the color match was excellent. The 28-layer coating is waterproof, scratch-resistant, and anti-glare.
With 101 reviews and a 4.4-star average, this filter has built a solid reputation. Filmmakers on Reddit’s videography community consistently recommend it as the best budget magnetic VND available. The included magnetic adapter ring means you have everything you need to start shooting immediately.
The magnetic swap works in about one second, which K&F claims is six times faster than threaded filters. In practice, I found this to be accurate. On a fast-moving shoot, that speed difference adds up quickly.
Who should buy this filter
Budget-conscious filmmakers who need a VND for run-and-gun shooting. If you are a student filmmaker, a small business owner producing your own video content, or anyone who wants professional-looking footage without spending hundreds, this is your filter.
It is also an excellent first magnetic filter. If you want to test whether a magnetic system fits your workflow before investing in a premium kit, the low entry cost makes this a low-risk trial.
What to watch out for
The magnets are adequate for shooting but not as strong as premium systems. Multiple users reported the filter getting knocked off when carrying the camera with the filter attached. Remove the filter when not actively shooting.
At wide angles, expect some vignetting at 16mm and a slight X-cross at maximum stops. If you primarily shoot at 24mm or longer and keep your VND below 4 stops, these issues will not affect you.
How to Choose a Magnetic Filter System for Filmmaking?
Choosing the best magnetic filter system for filmmakers comes down to four key factors. Here is what I learned from testing all eight systems.
Magnet strength and security
This is the single most important factor. A filter that falls off your lens during a shoot is worse than no filter at all. The NiSi JetMag Pro twist-lock system is the most secure I tested. The K&F Concept magnetic systems are functional but less secure in rough handling. If you shoot in demanding environments, prioritize systems with locking mechanisms over pure magnetic attachment.
Optical glass quality
The glass determines your image quality. Japanese AGC optical glass, used by K&F Concept and SmallRig, produces excellent results at lower price points. NiSi’s nano-coated optical glass and PolarPro’s cinema-grade quartz represent the premium tier. Look for multi-layer coatings that reduce reflections and repel water and oil.
Color cast is the enemy of video footage. Every filter in this guide produces minimal to negligible color cast. If you are considering a filter not listed here, check user reviews specifically for color shift complaints.
Fixed ND versus variable ND
Fixed ND filters (like the NiSi Landscape Kit’s ND8, ND64, ND1000) produce the cleanest images because they use a single glass element. Variable ND filters use two polarizing elements that rotate against each other, which can introduce cross-polarization artifacts at higher stops.
For filmmaking, VNDs offer unmatched convenience. You can adjust exposure without removing the filter, which is critical for run-and-gun shooting. If image purity is paramount, go with fixed NDs. If speed matters more, choose a VND.
System compatibility
Once you invest in a magnetic system, you are somewhat locked in. NiSi JetMag Pro adapters only work with JetMag Pro filters. K&F Concept magnetic rings only pair with K&F magnetic filters. Choose a brand that offers the filter types and sizes you need both now and in the future.
Check which thread sizes are available. If your lens collection spans 67mm, 77mm, and 82mm, make sure your chosen system supports all three. The NiSi JetMag Pro kits include multiple adapter sizes, which is a major advantage for multi-lens shooters.
Filter types you need
Most filmmakers need at minimum an ND filter for exposure control. If you shoot outdoors, a CPL (circular polarizer) is valuable for controlling reflections and enhancing skies. Diffusion filters like Black Mist add a cinematic softness that is increasingly popular in narrative and commercial work.
Kits that include multiple filter types offer better value than buying individual filters. The SmallRig 5-in-1 and K&F Concept 5-in-1 kits both provide a range of creative tools at a lower combined cost than purchasing separately.
Video-specific considerations
For video, the 180-degree shutter rule means you need ND filters to maintain proper motion blur at wide apertures in daylight. A 2 to 5 stop range covers most situations. If you shoot in extremely bright conditions or near water and snow, consider systems that extend to 6 or 10 stops.
Vignetting is more visible in video than in still photography because the frame is constantly in motion. Test any filter at your widest focal length before committing. The PolarPro PMVND performs well down to 16mm, while some budget options vignette at that range.
Frequently Asked Questions
What is the best magnetic filter system for filmmakers?
The NiSi JetMag Pro system is the best magnetic filter system for filmmakers overall, thanks to its patented twist-lock design, superior optical glass, and multi-size adapter compatibility. For budget-conscious filmmakers, the Ku0026amp;F Concept magnetic VND offers excellent value.
How do magnetic camera filters work?
Magnetic filter systems use rare-earth magnets built into filter frames that snap onto matching adapter rings mounted on your lens. The adapter ring threads onto your lens normally, then magnetic filters attach instantly without threading, allowing sub-second filter swaps during filming.
Are magnetic filters good for video production?
Yes, magnetic filters are excellent for video production because they allow rapid filter changes without disrupting your camera setup. Filmmakers frequently need to adjust ND filters as lighting changes between shots, and magnetic systems make these swaps fast enough to maintain shooting momentum.
What is the difference between magnetic and screw-in ND filters?
Screw-in filters thread directly onto your lens, which is secure but slow to change. Magnetic filters attach via magnets to an adapter ring, enabling instant swaps but with slightly less physical security. Magnetic systems are faster on set, while screw-in filters are more secure in rough conditions.
Which magnetic filter brand has the strongest magnets?
NiSi JetMag Pro has the strongest and most secure magnetic attachment system, featuring a patented twist-lock mechanism that combines magnetic attraction with a physical lock. PolarPro Helix MagLock and Maven magnetic systems also receive high marks for magnet strength from user communities.
Final Thoughts on the Best Magnetic Filter System for Filmmakers
After testing all eight systems, the NiSi JetMag Pro ecosystem stands out as the best magnetic filter system for filmmakers in 2026. The twist-lock security, optical quality, and multi-size adapter support make it the most complete solution for professional video production.
For filmmakers on a budget, the K&F Concept kits deliver remarkable value without sacrificing optical quality. And for content creators who want proven performance, the PolarPro McKinnon series remains a trusted choice backed by hundreds of user reviews.
The right filter system depends on your shooting style, your lens collection, and your budget. Any of these eight systems will serve you well. Pick the one that matches how you actually work on set.
