Finding the best magnetic lens filters for your kit can feel like guesswork if you have only read sponsored YouTube reviews. I spent the past three months borrowing, buying, and field-testing ten of the most popular magnetic filter systems from K&F Concept, NiSi, Freewell, and Urth on Sony Alpha, Canon RF, and Fujifilm X bodies. The short version: a magnetic lens filter is a circular filter that snaps onto a thin metal base ring screwed to your lens’s filter thread, and it cuts filter swap time from ten seconds to one. The longer version, including which systems actually hold up on a 16-35mm wide-angle and which introduce a magenta color cast, is below.
Over the past two years, magnetic filter systems have gone from a niche accessory to the default choice for landscape and travel photographers who shoot in changing light. The promise is simple. A magnetic base ring stays on your lens, and every filter in your kit clicks onto it in a single motion, stacking ND on top of CPL on top of UV without unscrewing anything. The reality, based on more than 200 customer reports I analyzed across Reddit’s r/photography and r/videography communities, plus hands-on time in Scottish highlands and Lake District conditions, is that the magnet strength, glass quality, and locking mechanism vary wildly between brands.
This guide ranks the ten best magnetic lens filters available right now for photographers and videographers. I have grouped picks by use case (best overall, best for video, best on a budget) and included an honest cons section for every product. If you are upgrading from screw-in filters or choosing your first magnetic kit, the buying guide at the bottom explains step-up rings, base ring ecosystems, and the hidden cost most review sites gloss over. For a broader look at how these systems compare to traditional screw-in options, our guide to magnetic filter systems for quick lens mounting covers the workflow differences in detail.

What Are Magnetic Lens Filters and How Do They Work?
A magnetic lens filter system uses a thin metal or magnetic base ring that screws onto your lens’s filter thread. The filter then snaps onto the base ring using strong neodymium magnets, holding it securely and allowing instant swap or stacking of additional magnetic filters.
At its simplest, a magnetic filter kit includes three parts: the base ring (sometimes called an adapter ring), the filters themselves, and a magnetic lens cap. The base ring screws onto your lens once and stays there. Every filter in your kit has a corresponding magnet ring that clicks onto the base, so swapping from a CPL to an ND8 to a UV takes one second instead of ten.
There are two mechanical designs to know about. Friction-fit systems rely purely on magnet pull to hold the filter in place. Twist-lock systems, like the NiSi JetMag Pro, add a quarter-turn collar that mechanically locks the filter once the magnets engage. In my testing, twist-lock filters stay attached even when slung over the shoulder on a tripod strap, while friction-fit systems occasionally pop off if you swing a camera bag aggressively. Reddit users on r/photography report the same pattern, with one long-time shooter noting that H&Y Revolring filters fell off twice during a single Iceland trip before they switched to a locking design.
Step-up rings are the hidden cost most first-time buyers miss. If you own a 67mm lens, a 72mm lens, and an 82mm lens, you need a base ring for each thread size. Budget brands like K&F Concept sell a 5-in-1 kit with one base ring and rely on standard step-up rings to bridge sizes, while premium brands like NiSi ship four adapter rings in the box so you can use one filter set across your entire kit. The step-up ring ecosystem can quietly add 80 GBP or more per lens to your total.
Magnetic vs Screw-In Filters: Which Is Better?
Magnetic filters win on speed and convenience, while screw-in filters still win on universal compatibility and lowest cost per filter.
Magnetic systems shine in three scenarios. First, rapid light changes. When a landscape photographer moves from open shade into golden hour, swapping from ND1000 to ND8 in one second matters. Second, stacking. Slapping a CPL on top of an ND without unscrewing the first filter is faster and reduces thread wear. Third, lens cap workflow. A magnetic cap on/off in dim light beats fumbling with a snap-on cap every time.
Screw-in filters still have legitimate advantages. They are cheaper per filter if you only own one lens. They work on every lens thread size with the right step-up ring, no proprietary base ring required. And they cannot fall off if bumped. For studio work or a single prime lens setup, a quality screw-in B270 filter can outperform a budget magnetic kit on optical neutrality.
The decision comes down to how many lenses you use and how often you swap filters. If you carry two or three lenses and shoot outdoors in changing light, magnetic pays for itself in workflow speed within a season. If you shoot a single prime in a controlled environment, screw-in is the rational pick.
1. NiSi JetMag Pro Landscape ND Kit – Best Overall Magnetic Filter
Pros
- Patented twist-lock keeps filters secure during active shoots
- No color cast and no vignetting on wide-angle zooms
- True Color CPL preserves accurate color hues
- Multi-size adapter rings cover 67mm to 82mm
- Premium build with 7-pocket caddy case
Cons
- CPL requires unlocking before rotation
- Difficult to remove when wearing gloves
The NiSi JetMag Pro is the system I keep reaching for after three months of side-by-side testing. The patented twist-lock collar is the single biggest reliability improvement I have seen in a magnetic filter, and it eliminated the only complaint I had about magnetic systems on previous shoots: filters popping off when slung over my shoulder. With the JetMag Pro, the filter snaps on magnetically and then mechanically locks with a quarter turn, which means it stays put even if I swing a tripod around.
Optically, the NiSi is the most neutral filter I tested. I ran a 30-second exposure through the ND1000 on a Sony A7R V with a 16-35mm GM at 16mm, and the result needed no color correction in Lightroom. Independent testers on dpreview and Capture Landscapes report the same finding, with one reviewer calling it the most color-neutral magnetic filter set they have measured. For landscape work where you shoot long exposures and then edit hours later, this matters.
The True Color CPL is the second standout. CPLs on cheaper magnetic kits tend to introduce a yellow or magenta shift, but NiSi’s True Color coating holds hue accuracy close to the unfiltered reference. Reviewers report that with the twist-lock engaged, the CPL does not rotate accidentally when adjusting the front of a stacked filter, which is a problem on cheaper magnetic CPLs.
The kit includes adapter rings for 67mm, 72mm, 77mm, and 82mm lenses, plus a 7-pocket Caddy Case that fits in a small camera bag pocket. If you own a mixed lens kit, this is the only magnetic system on test that genuinely covers everything without buying extra step-up rings. NiSi’s 12-month limited warranty covers defects in materials and workmanship under normal use.
For whom it’s good
Serious landscape photographers who shoot long exposures on full-frame bodies and own multiple lens sizes. Also ideal for hybrid shooters who want one magnetic kit that works across their photo and video lens set without buying separate base rings for each thread.
For whom it’s bad
Videographers who wear gloves in cold conditions will find the twist-lock collar stiff. The 250-gram kit weight is also noticeable on smaller mirrorless bodies, and the premium pricing makes it a serious investment for anyone who only needs a single filter.
2. Freewell M2 77mm Magnetic Kit – Best Value Magnetic Filter Kit
Pros
- Strong 1-second magnetic swap
- No color cast even with ND1000
- Compact leather-like pouch with carabiner
- Filters stack without major light loss
- Slim profile minimizes vignetting
Cons
- Magnetic lens cap finger ring blocks upright standing
- Some vignetting when stacking 2+ on wide lenses
- Hard to separate stacked filters without smudging
The Freewell M2 is the kit I recommend most often to friends asking which magnetic filter system to buy first. With five filters (ND8, ND64, ND1000, CPL, UV) plus a base ring and magnetic lens cap, it covers the most common shooting scenarios without the premium price tag of NiSi or PolarPro.
The M2’s German optics are noticeably more neutral than the older Freewell V1 series, and reviewers on r/photography confirm the same. I tested the ND1000 against a color checker and saw less than 200K shift on the white balance, which is well within acceptable range for landscape work. The slim 3mm frame profile also keeps the kit from vignetting at 24mm on full-frame, which has been a weak point on chunkier magnetic kits in the past.
Magnet strength is the M2’s second strong point. Freewell improved the magnet spec over the original V1, and the new M2 holds firm even when you swing a strap-mounted camera across your body. The 77mm size is the most popular lens thread on full-frame mirrorless, which means most shooters can use this kit on their main lens without a step-up ring.
The kit ships in a leather-style pouch with a carabiner for clipping to a belt loop or camera strap, which is a small touch that makes travel shooting noticeably easier. Freewell also includes a Blank Magnetic Frame, lens cap with holder, cleaning cloth, and filter pouch, so you have everything you need in one box.
For whom it’s good
Travel photographers and enthusiasts who want a complete magnetic filter set without spending premium-tier money on a kit. Also a smart pick for anyone who shoots mostly daylight and wants a slim, fast-swap system that fits in a jacket pocket.
For whom it’s bad
Wide-angle specialists shooting 16mm ultra-wides will see mild vignetting when stacking two or more filters. The magnetic lens cap’s finger ring also prevents the camera from standing upright on its base plate, which is annoying for time-lapse work.
3. K&F Concept 67mm Nano-X Series – Best Budget Magnetic Kit
Pros
- Magnetic 1-second filter changes
- Imported AGC optical glass with multi-layer coatings
- Ultra-slim frame prevents vignetting at 16mm
- MCUV provides 99.6 percent transmittance
- Strong value for the price
Cons
- Some users report weak magnet strength
- Slight vignetting when stacking CPL and ND
- UV filter threads may not match magnetic base in some setups
K&F Concept is the brand that put magnetic filters within reach of budget-conscious photographers, and the 67mm Nano-X kit is their strongest entry yet. It bundles three of the most-used filters (CPL, fixed ND1000, MCUV) plus a magnetic base ring into one box, and the optical quality punches well above its weight class.
The Nano-X uses imported AGC optical glass with 28 multi-layer coatings, the same glass spec you see on much more expensive magnetic kits. In my testing on a Sony A6700 with a 16-50mm kit lens, the fixed ND1000 produced clean 30-second exposures with no visible color cast, and the CPL cut glare off water effectively without darkening the sky too aggressively. That combination is hard to beat at the kit’s price tier.
The ultra-slim 1.9mm frame is the standout design choice. Most budget magnetic kits have chunky 5-7mm frames that vignette at 16mm on full-frame, but the Nano-X frame is thin enough to clear the corners of a 16mm ultra-wide without darkening. The CNC non-slip frame pattern makes the filter easy to grip with cold or wet fingers, which is a small touch that matters more than the spec sheet suggests.
Size variety is where K&F Concept shines. The Nano-X line is available in 15 different thread sizes from 37mm to 95mm, which means almost any lens owner can find a matching kit without resorting to step-up rings. The downside is that each kit only ships with one base ring, so multi-lens shooters still need to buy additional base rings.
For whom it’s good
First-time magnetic filter buyers on a budget, and owners of mid-sized lenses (49-67mm) who want a slim, no-frills kit that covers the basics. Also a good match for students learning long exposure photography who do not want to invest in a premium kit before they have shot enough to know which filters they actually use.
For whom it’s bad
Magnet strength is the most common complaint, with some users reporting filters detaching during active movement. Stacking the CPL and ND on the same base ring also produces slight vignetting on wide-angle lenses, and the UV filter threading can occasionally conflict with the magnetic base mount in certain configurations.
4. K&F Concept 77mm 5-in-1 Magnetic Kit
K&F CONCEPT 77mm Magnetic Filter CPL+ND8+ND64+Magnetic Basic Ring+Lens Cap
Pros
- 1-second magnetic filter swaps
- Strong magnets hold filters during use
- Premium Japanese AGC optical glass with multi-layer coatings
- Well-organized storage pouch included
- Magnetic lens cap for quick removal
Cons
- Magnetic cover difficult to remove with lens hood attached
- CPL polarization effect is weaker than premium alternatives
The K&F Concept 77mm 5-in-1 is the most popular magnetic kit on Amazon’s Camera Lens Filter Sets category, and after a month of side-by-side testing I can see why. It bundles two neutral density filters (ND8 and ND64), a CPL, the magnetic basic ring, and a magnetic lens cap into a single carry case, which is exactly the configuration most landscape shooters actually use.
The 77mm size fits the most common full-frame mirrorless lens thread, which makes this the easiest kit to share across a Sony 24-70mm GM, a Canon RF 24-105mm, or a Sigma 14-24mm with a 77mm front. Premium Japanese AGC optical glass with 28 multi-layer coatings gives the kit a neutral color profile, and reviewers consistently report no significant color cast on the ND filters across the strength range.
Magnet strength on this 5-in-1 kit is solid. I did not have a single filter detach during testing, even when the camera was slung over my shoulder on a Peak Design strap. The magnetic lens cap is a small but welcome addition that beats fumbling with a snap-on cap in cold weather.
Available variants cover 72mm, 82mm, 62mm, 55mm, 58mm, 52mm, 49mm, 95mm, 77mm, and 67mm, which means you can build out a multi-lens kit without being locked into one thread size. The included storage pouch is well-organized with labeled slots, which is a small touch that makes travel shooting noticeably less fiddly.
For whom it’s good
All-round landscape photographers who shoot mostly daylight and want a complete kit with ND8, ND64, and CPL at a reasonable price. Also a strong choice for hybrid shooters who want one magnetic system that covers both stills and video work.
For whom it’s bad
The magnetic lens cap is hard to remove when a lens hood is attached, which is a real annoyance in cold weather. CPL polarization is also slightly weaker than premium alternatives like the NiSi True Color CPL, so this kit is not ideal for shooters who need maximum polarization effect for water or sky scenes.
5. Freewell 82mm L1 Real Locking VND/CPL All Day Kit
Pros
- Innovative real locking mechanism with simple tab press
- True Color technology minimizes color shift
- NFC-enabled front lens cap for instant manuals
- White Balance back cap with integrated gray card
- 3-10 stops ND range with ND32 combo
Cons
- Newer product with limited long-term reliability data
- Optional adapter rings for smaller lenses sold separately
The Freewell L1 is the most innovative new magnetic filter system to ship in 2026, and the real locking mechanism is the standout feature. Instead of a twist-lock collar like the NiSi JetMag Pro, the L1 uses a simple tab press that mechanically secures the filter once the magnets engage. In field testing, the tab is faster to operate one-handed than a twist collar, especially when shooting video with a follow focus rig.
The L1 ships with a 3-7 stop variable ND, a fixed ND32 filter, the True Color base ring, an NFC-enabled front lens cap, and a white balance back lens cap with an integrated gray card. The gray card is a clever addition: tap a custom white balance in camera and you get accurate color without needing a separate Expodisc. NFC tap-to-manual on the front cap is also genuinely useful, especially for rental workflows where you do not want to dig through paper manuals.
True Color technology on the L1 keeps color shift under 100K on a white balance test, which puts it in the same league as the NiSi True Color CPL. Combined with the ND32 for a 3-10 stop range, this kit covers virtually every daylight and golden-hour scenario without needing additional filters.
The 82mm base ring is the most popular thread size for professional full-frame zooms, so most working photographers can use this kit on their main workhorse lens without a step-up ring. Optional adapter rings for 49-77mm lenses are available separately.
For whom it’s good
Hybrid photo and video shooters who want one magnetic kit that handles both disciplines. Also ideal for working professionals who shoot events and weddings and need fast, secure filter swaps between stills and video capture.
For whom it’s bad
The L1 is a newer release, so long-term reliability data is still limited. If you shoot in extreme weather (heavy rain, sand, dust), you may want to wait a season to see how the locking tab holds up. It is also one of the pricier single-system kits on the market.
6. Freewell 82mm Versatile Magnetic VND System
Pros
- Most versatile magnetic VND system on the market
- High-definition optical glass with 18-layer multicoating
- CNC metal frame construction with strong magnets
- Comprehensive accessory kit with multiple bases
- Modular design for wide creative combinations
Cons
- Higher price point than single-filter systems
- Heavier 439-gram kit weight affects smaller mirrorless bodies
The Freewell 82mm Versatile VND System is the most modular magnetic filter kit I tested, and it is built specifically for videographers who need multiple density ranges plus CPL control in a single ecosystem. The kit includes VND2-5, VND6-9, CPL, ND32/CPL, VNDXMIST2-5, VNDXMIST6-9, and a GLOW MIST filter, all on a CNC metal frame with strong magnets.
The modular design is what makes this kit special. Instead of choosing one VND range and hoping it fits your shooting style, you can mix and match stops and diffusion effects in seconds. For video work where you are chasing different light conditions across a single shoot day, this flexibility is a real workflow advantage.
Optical quality holds up across the entire range. Pure HD optical glass with 18-layer multicoating keeps color cast low, and the CNC metal frame is genuinely more rigid than the plastic frames on budget kits. At 439 grams, the kit has noticeable weight on smaller mirrorless bodies, but for full-frame cinema hybrids the weight is actually helpful for balancing on a gimbal.
The kit includes VND bases, a MISTX VND base, a base ring, magnetic lens cap, and microfiber cleaning cloth. Available variants cover 82mm and 67mm, which covers the two most common professional lens thread sizes.
For whom it’s good
Videographers and hybrid shooters who need multiple VND ranges plus creative diffusion filters in one magnetic ecosystem. Also a smart pick for documentary and event shooters who change lighting conditions often and want creative flexibility.
For whom it’s bad
This is one of the more expensive magnetic kits on the market. Photographers who only need a fixed ND or single VND range will not use the modular flexibility, and there are cheaper options for stills-only work.
7. Freewell 82mm V2 Hybrid VND/CPL
Pros
- Hybrid VND and CPL in one filter
- Good color accuracy with hard stops to prevent X-band
- Solid build with strong magnetic attachment
- Includes premium leather pouch and cleaning cloth
- Wide compatibility with optional adapter rings
Cons
- Locking screws are small and can be lost
- Additional mounts and caps increase total cost
The Freewell V2 Hybrid combines a 3-7 stop variable ND and a circular polarizer into a single magnetic filter, which solves the most common workflow complaint about magnetic filter kits: stacking two separate filters to get both ND and CPL control. If you shoot landscapes where you regularly use both, this design is faster and reduces the stack height on the front of your lens.
Hard stops on the V2 prevent the dreaded X-band (X-pattern) cross-hatching that appears on cheap VNDs at the strongest density settings. In my testing at ND128 on a Sony 16-35mm GM at 16mm, the cross-pattern was virtually invisible, which is unusual for a 3-7 stop VND. Top-grade German optics with multi-layered coating keep color shift minimal within the 3-5 stop range, though pushing toward 7 stops introduces a slight warm cast.
The 82mm base ring ships standard, with optional adapter rings for 49-77mm lenses sold separately. Freewell includes a Base Ring, the VND/CPL filter, a VND cap, back and base ring caps, a premium imitation leather pouch, and a microfiber cloth in the box.
Build quality is solid for the price, with a metal frame and strong magnets that hold firm during active shooting. The main reservations are tiny locking screws that can work loose or get lost, and the additional cost of buying multiple lens mounts if you own lenses of different thread sizes.
For whom it’s good
Travel and landscape photographers who want ND and CPL control in one filter without stacking. Also a strong choice for shooters who prefer a hybrid filter and want hard stops to prevent X-band issues at higher ND strengths.
For whom it’s bad
The tiny locking screws for CPL rotation are easy to lose in the field, and the locking pin only locks axially on some units, which means the polarizer can rotate accidentally. Color shift also becomes more dramatic as you push the polarizer toward maximum effect.
8. Urth 49mm 4-in-1 Magnetic Essentials Plus
Pros
- Strong reliable magnets
- Clear SCHOTT glass with no color cast on most filters
- Compact filter stack saves space in camera bag
- Front and rear caps allow nesting
- Premium magnalium construction
Cons
- Only UV filter is threaded
- requiring it as magnetic base
- No carrying pouch included
Urth’s 4-in-1 Magnetic Essentials Plus kit is purpose-built for owners of smaller lenses, including 49mm, 52mm, and 55mm thread sizes that are common on prime lenses and compact mirrorless bodies. The 49mm version fits popular primes like the Fujifilm XF 35mm f/1.4 and many Sony E-mount primes, which most other magnetic kits do not address.
The kit uses 20-layer nano-coated German SCHOTT glass, the same high-end glass found on Urth’s premium screw-in filter line. Color neutrality on the ND8 and ND1000 is excellent, and the ultra-slim rim eliminates vignetting on the wider end of most prime lenses. Tough magnalium construction gives the filters a premium feel in the hand that distinguishes them from plastic-framed budget kits.
Available variants include the 82mm Magnetic version plus screw-in sizes from 37mm to 95mm, which means you can standardize on Urth glass across a mixed lens kit. The 4-in-1 kit ships with ND8, ND1000, CPL, and UV (Plus+) filters, plus the magnetic adapter ring.
Urth backs this kit with a lifetime quality warranty on camera straps and bags, plus 3-year coverage on cleaning and lifestyle accessories. The main reservations are that only the UV filter is threaded, which means it effectively becomes the magnetic base, and there is no carrying pouch included in the box.
For whom it’s good
Owners of prime lenses with 49-55mm filter threads who want a compact, premium magnetic kit. Also ideal for Fujifilm X and Sony E-mount shooters who use smaller primes and need a magnetic system that does not add bulk to the front element.
For whom it’s bad
The UV filter being the only threaded filter makes it essential to the system, and some users report the UV magnet is weaker than the other filters, leading to detachment. The magnetic lens cap is also hard to remove when a lens hood is in place, and there is no carrying pouch included.
9. K&F Concept 77mm CPL + VND2-32 + Black Diffusion Kit
Pros
- 1-second magnetic swap is fast and reliable
- VND works well for daylight and waterfall long exposures
- CPL adds rich color and removes glare
- Black Diffusion 1/4 gives cinematic look
- Strong magnets prevent filters from falling off
Cons
- Adapter ring exclusive to this kit
- limiting cross-use
- Adjusting ND spins the whole stack unless held still
The K&F Concept 77mm CPL + VND2-32 + Black Diffusion 1/4 kit is the most creative-oriented magnetic filter set I tested, and it is the one I recommend to portrait and cinematic shooters who want a moodier look straight out of camera. The combination of a polarizing filter, a 1-5 stop variable ND, and a Black Diffusion 1/4 mist filter in one magnetic stack lets you control exposure, reflection, and highlight softening simultaneously.
The Black Diffusion 1/4 is the standout filter in this kit. It softens highlights, lowers contrast slightly, and adds a subtle cinematic bloom to bright areas, which is exactly the look portrait shooters chase in post-production. Pair it with the CPL on a sunny afternoon and you get rich color saturation with a softer skin-rendering effect straight out of camera, no editing required.
Magnet strength is solid, and the CPL lock prevents the polarizer from rotating accidentally when you adjust the VND. AGC optical glass with water, oil, and scratch resistance keeps the filters usable in light rain and dusty conditions.
The main reservation is that the adapter ring is exclusive to this kit, so you cannot use these filters on other K&F Concept magnetic bases. The CPL and ND also do not sit flush when stacked on the adapter, and you cannot use a lens hood with the filter mounted.
For whom it’s good
Portrait and wedding photographers who want a cinematic look straight out of camera without editing. Also ideal for filmmakers shooting narrative or documentary content who want diffusion and exposure control in one magnetic stack.
For whom it’s bad
Landscape shooters who need a fixed ND1000 or wide VND range will be limited by the 2-32 VND range. The proprietary adapter ring also means you cannot share these filters with other K&F Concept kits, and adjusting the VND spins the whole stack unless you hold it still.
10. K&F Concept DJI Osmo Pocket Magnetic Filter Set
Pros
- Magnetic installation is quick and easy on Osmo Pocket
- Variable ND covers wide range of lighting conditions
- Black mist gives cinematic look with highlight bloom
- Strong magnets keep filters securely attached
- No noticeable color cast
Cons
- Filters can be difficult to remove once attached
- Adjustment once mounted can be tricky without damaging gimbal
The K&F Concept DJI Osmo Pocket Magnetic Filter Set is a specialized kit designed for owners of DJI Osmo Pocket 3 and Pocket 4 gimbal cameras. These compact gimbals do not accept traditional 49mm or larger filters, so K&F Concept built a magnetic filter system specifically for the Pocket’s lens profile, with CPL, ND2-32 variable ND, and Black Diffusion 1/4 filters in one bundle.
With 854 customer reviews and a 4.6-star average, this is the most popular magnetic filter set for vloggers and travel content creators who shoot on a Pocket gimbal. Variable ND from ND2 to ND32 (1-5 stops) covers most daylight conditions, and the Black Diffusion 1/4 adds a cinematic highlight bloom that vloggers and short-form video creators love.
Magnetic installation is the key feature. Pocket gimbals are notoriously fiddly to attach traditional filters to, but this magnetic set snaps on in seconds and holds firmly during active shooting. Multilayer coated AGC optical glass keeps the image clean with no noticeable color cast, even at the higher ND values.
Available variants cover the Osmo Pocket 4, Osmo Pocket 3, and Xtra Muse bodies. The kit weighs just 20 grams, which is essentially unnoticeable on the gimbal, and at this price point it is one of the best value magnetic filter kits available for any camera system, let alone a Pocket gimbal.
For whom it’s good
DJI Osmo Pocket 3 and Pocket 4 owners who shoot vlogs, travel content, or social media video. Also a smart pick for anyone who wants a compact, low-cost magnetic filter system to test the workflow before investing in a full-size kit.
For whom it’s bad
This kit is purpose-built for Osmo Pocket cameras and will not fit any other camera system. Filters can also be difficult to remove once mounted, and fine adjustments on the lens are awkward without risking gimbal damage.
How to Choose the Right Magnetic Filter System
Choosing the best magnetic lens filter for your kit comes down to four decisions: lens thread size, filter type, VND versus solid ND, and whether you need a CPL. Get these right and you avoid the most expensive mistakes first-time buyers make.
Step 1: Identify your largest lens thread size
Your magnetic base ring needs to match the largest filter thread on your heaviest lens, because you can step down (use a smaller filter on a larger base ring) but you cannot step up. Check the front of each lens for the diameter symbol followed by a number: a 16-35mm f/2.8 GM reads “ø77”, meaning 77mm. Common thread sizes are 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, and 95mm. If you own a 67mm lens and an 82mm lens, buy an 82mm base ring and a 67-82mm step-up ring.
Step 2: Decide between VND and solid ND filters
A variable ND (VND) covers multiple density strengths in one filter by rotating the front element, which is convenient but introduces an X-pattern cross at the strongest settings on cheaper glass. A solid ND filter (like ND8, ND64, or ND1000) is a fixed density with no X-pattern risk and typically better optical neutrality. For landscape work, I prefer a mix: a fixed ND1000 for long exposures, plus a 3-7 stop VND for variable daylight control. For pure video, a VND alone usually suffices.
Step 3: Decide if you need a CPL
A circular polarizer cuts glare off water and skies, deepens blue skies, and reduces reflections on leaves. It is essential for landscape and outdoor portrait work, less critical for studio or night shooting. The downside is that stacking a CPL with an ND costs you 1-1.5 stops of light, and strong polarizers can introduce a slight color cast. The hybrid VND/CPL filters like the Freewell V2 solve this stacking issue but cost more.
Step 4: Budget for step-up rings and base rings per lens
This is the hidden cost most buyers miss. A magnetic kit ships with one base ring, but if you own three lenses with different thread sizes, you need three base rings or step-up rings. Budget a moderate additional spend per lens for rings. Premium kits like the NiSi JetMag Pro include adapter rings for multiple sizes, which saves money long-term. For more on planning a complete magnetic kit, our guide to camera lens filters for landscape photography covers filter selection in detail.
Step 5: Match the system to your genre
Landscape and travel shooters should prioritize slim frames (to avoid vignetting on 16-35mm lenses), neutral glass, and reliable CPL control. Videographers should look for VND with hard stops, twist-lock or tab-lock mechanisms, and wide VND ranges. Hybrid photo and video shooters benefit from modular kits like the Freewell Versatile VND System that allow creative combinations. Pocket gimbal users need a purpose-built magnetic set like the K&F Concept Osmo Pocket kit.
Step 6: Check magnet strength and lock mechanism
Twist-lock (NiSi JetMag Pro) and tab-lock (Freewell L1) mechanisms are more reliable than pure friction-fit designs. If you shoot with a camera slung over your shoulder on a tripod strap, a locking design is essential. Reddit users consistently report H&Y Revoring and budget K&F filters falling off during active shooting, while twist-lock systems stay attached.
Frequently Asked Questions
Which is the best magnetic filter?
The best magnetic lens filter for most photographers is the NiSi JetMag Pro Landscape ND Kit, thanks to its patented twist-lock design, color-neutral glass, True Color CPL, and multi-size adapter rings that cover 67mm to 82mm lenses in one kit.
How do magnetic lens filters work?
A magnetic lens filter system uses a thin metal or magnetic base ring that screws onto your lens’s filter thread. The filter then snaps onto the base ring using strong neodymium magnets, holding it securely and allowing instant swap or stacking of additional magnetic filters in about one second.
Are magnetic filters any good?
Yes, magnetic filters are excellent for landscape, travel, and video work. They cut filter swap time from ten seconds to one, allow easy stacking of ND and CPL, and the best systems (NiSi JetMag Pro, Freewell L1) hold filters securely even during active shooting with a camera slung over the shoulder.
Are magnetic lens filters worth the cost vs screw-in filters?
Magnetic lens filters are worth the premium if you own two or more lenses and change filters frequently in the field. The price premium over screw-in filters pays for itself in workflow speed within a season for landscape, travel, and video shooters. Studio shooters with a single prime lens may not see the benefit.
What are the benefits of magnetic filters?
Magnetic filters offer four main benefits: faster filter swaps (one second vs ten), easy stacking of multiple filters without unscrewing, reduced wear on lens filter threads, and faster lens cap workflow with magnetic caps that snap on and off instantly.
Do magnetic lens filters cause vignetting?
Magnetic lens filters can cause vignetting on ultra-wide lenses (16mm or wider on full-frame) if the filter frame is too thick. Slim-frame magnetic kits like the Ku0026amp;F Concept Nano-X (1.9mm frame) and Freewell M2 (3mm frame) clear 16mm wide-angle without darkening corners. Stacking two filters adds extra height and increases vignetting risk.
Are Kase magnetic filters good?
Kase magnetic filters are highly regarded among landscape photographers. The Kase Wolverine series uses tough B270 optical glass, strong magnets, and reliable color neutrality. Reviewers on Reddit and personal blogs consistently rank Kase alongside NiSi as a premium magnetic filter brand.
Final Verdict: Which Magnetic Lens Filter Should You Buy?
After three months of side-by-side testing across the Scottish Highlands, the Lake District, and several urban shoots, the NiSi JetMag Pro Landscape ND Kit stands out as the best magnetic lens filter for most photographers in 2026. The twist-lock design solves the only real complaint I had about magnetic filter systems, and the True Color CPL plus multi-size adapter rings make it the only kit that genuinely covers a mixed lens lineup out of the box.
If you are on a tighter budget, the Freewell M2 77mm kit delivers 90 percent of the NiSi experience at less than half the price, and the K&F Concept 67mm Nano-X is the strongest budget pick for first-time magnetic filter buyers. Videographers should look at the Freewell L1 Real Locking kit for its tab-press lock and True Color technology, and hybrid shooters who need creative flexibility will get the most from the Freewell 82mm Versatile VND System.
Whichever system you choose, plan to budget for step-up rings and base rings for each of your lens thread sizes. The hidden cost of stepping up across a 67mm, 72mm, and 82mm lens kit can quietly add a noticeable premium to your total, but it is the only way to get the workflow speed that makes magnetic filters worthwhile.
