I have been flying with this All Day 6-Pack on my Mini 3 Pro for over eight months now. The difference in footage quality is night and day. Before these filters, I was stuck with shutter speeds of 1/1000 or faster in bright sun, giving me that jittery, unnatural motion that screams amateur video.

With the ND64 installed, I can hit that sweet spot of 1/60 shutter speed for 30fps video, even at midday. The motion blur looks natural and cinematic. What impressed me most was the weight, or lack of it. At just 0.7 grams per filter, my gimbal calibration never budged, and I never got that dreaded gimbal overload warning that heavier filters can cause.

The multi-coating is legitimately color neutral. I have shot the same scene with and without filters, and the color temperature stays consistent. No weird magenta or green shifts that I have seen with cheaper alternatives. The scratch-resistant coating has held up through dozens of installations in dusty desert conditions.

Installation is straightforward once you get the hang of it. The filters thread on smoothly, and the included case keeps everything organized in my drone bag. I appreciate that Freewell includes a cleaning cloth because these filters attract fingerprints like magnets during swaps.

The range from ND4 to ND1000 covers every situation I have encountered. ND4 and ND8 handle cloudy days and golden hour. ND32 and ND64 tackle bright sun. I have even used ND1000 for some creative long-exposure work of waterfalls during the day, something impossible without heavy filtration.

Freewell All Day - 6Pack ND4, ND8, ND16, ND32, ND64, ND1000 Filters Compatible with Mini 3 Pro/Mini 3 customer photo 2

Who Should Buy This

This 6-Pack is ideal for Mini 3 or Mini 3 Pro owners who want comprehensive filter coverage at an accessible tier. If you shoot video regularly in varying light conditions and want professional-looking motion blur, this set delivers. The GimbalSafe technology makes it perfect for the weight-conscious sub-250g regulations too.

Key Considerations

Make absolutely sure you own a Mini 3 Pro or Mini 3. These are NOT compatible with the Mini 4 Pro, which has a different lens design. Also, casual users might find they primarily use only two or three filters, so consider if the full range makes sense for your shooting habits.

The Standard Day Kit for the DJI Flip represents the best entry point into ND filters for new drone pilots. I tested these on a friend’s Flip drone during a beach vacation, and honestly, the performance exceeds what you would expect from an entry-level option.

The set includes ND8, ND16, ND32, ND64, and ND128, plus a dedicated PL polarizer. That PL filter alone transforms footage near water. I shot footage of waves breaking on rocks, and the polarizer cut through the glare on the water surface, revealing the rocks beneath in vivid detail.

The lightweight design is crucial for the Flip. This is a compact drone where every gram matters. These filters do not affect flight time or gimbal performance. I was getting the same 31-minute flight times with and without filters installed.

Installation requires some care. The removal tabs are thin plastic that can snap if you are rough with them. I found the best technique is to use the included removal tool and apply gentle, even pressure. Do not force anything, or you will end up with broken tabs like some frustrated reviewers mentioned.

The ND128 is a nice addition for long exposure work. I got some smooth, misty waterfall shots that look like they came from a DSLR on a tripod, not a drone hovering in the air. The optical quality punches way above its entry tier.

Who Should Buy This

DJI Flip owners who want better video quality at an entry tier. This is the perfect starter kit for new drone pilots learning about shutter speed and motion blur. The included polarizer makes it especially valuable for anyone shooting near water, snow, or reflective surfaces.

Key Considerations

Handle these with care. The plastic tabs are the weak point. Also, some users reported fit issues, so test immediately upon receipt. If they do not snap securely into place, contact Freewell for replacements rather than risking a lost filter mid-flight.

The Mavic 4 Pro is DJI’s flagship consumer drone with a unique dual focal length system. Standard filters do not work well with its variable aperture design. Freewell solved this with split ND filters that have different strengths for each camera.

I borrowed a Mavic 4 Pro for a weekend real estate shoot to test this 8-Pack. The split ND filters, like ND8/4 and ND16/8, let me balance exposure between the wide and tele cameras simultaneously. Without these, one camera would be properly exposed while the other blew out or crushed shadows.

The optical quality is noticeably better than entry tier options. Edge-to-edge sharpness is maintained, and the multi-coating handles flare well when shooting toward the sun. The polarizers are particularly effective for enhancing blue skies and cutting reflections on building windows during real estate work.

Gimbal-Safe Technology is essential here. The Mavic 4 Pro’s gimbal is sophisticated but sensitive to weight imbalances. These filters install flush and do not interfere with the full range of motion, even during aggressive maneuvers.

The 8-filter set gives you every option. ND8/4 through ND64/32 for split exposure control, plus dedicated ND/PL versions for glare-heavy scenarios. I used the ND64/32 for bright midday mansion exteriors and the ND16/PL for pool shots where reflections were an issue.

Who Should Buy This

Professional Mavic 4 Pro pilots who demand the best optical performance. This is for commercial operators, real estate photographers, and serious content creators who need reliable results on paid gigs. The split ND design is essential for anyone using both cameras in video mode.

Key Considerations

The case is a disappointment for a premium product. It does not seal, so dust and debris get inside. Plan on cleaning filters before each flight. This represents a higher investment tier, but the dual-camera optimization justifies the cost for professional use.

Pros

  • Combines ND and CPL in each filter
  • Reduces glare from water and glass
  • Enhances color saturation
  • Easy to swap in the field
  • Magnetic protective case included
  • Dustproof and scratch resistant

This Bright Day 6-Pack takes a different approach than the standard All Day set. Instead of pure ND filters, each one combines neutral density with a circular polarizer. The result is fewer filters to carry but more functionality per filter.

I tested these during a coastal road trip in California. Being able to cut through water glare while controlling exposure was a game-changer for ocean footage. The polarization marks on the rim let me dial in the exact amount of glare reduction before takeoff.

The range covers ND4/PL through ND64/PL, plus a dedicated CPL filter. That is essentially 12 functions in 6 physical filters. For travel when space is limited, this hybrid approach makes sense. I fit the entire set, case and all, in a side pocket of my drone bag.

Image quality is excellent. The polarizer does not introduce cross-polarization artifacts when aligned properly. I saw no vignetting even at the widest Mini 3 Pro angles. The waterproof coating came in handy when I got caught in a light drizzle, water just beaded up and wiped off.

The aluminum construction feels premium. These thread on smoothly and seat firmly. I never had one loosen in flight, which is a real concern with cheaper filters.

Who Should Buy This

Mini 3 Pro pilots who shoot near water, snow, or reflective surfaces. If you travel frequently and want maximum functionality with minimum gear, these hybrids are perfect. The polarization enhancement makes landscapes pop in ways pure ND filters cannot.

Key Considerations

You must set the polarization angle before takeoff. Once airborne, you cannot rotate the filter. This takes practice to get right. Also, the filters are small and easy to fumble when swapping in the field. Work over a surface where they will not disappear if dropped.

The Mini 4 Pro uses a different lens design than its predecessor, requiring specifically designed filters. This All Day 6-Pack is built exclusively for the Mini 4 Pro with the proper thread size and clearance.

I flew with these for two weeks in Arizona, dealing with extremely bright desert sun. The range starting at ND16 makes sense for the Mini 4 Pro’s improved sensor and wider aperture. Even at sunrise, I never wished for a lighter ND4 option. The sensor handles low light well enough that ND16 was my starting point.

Build quality matches the Mini 3 Pro version. Real optical glass, multi-coating that resists fingerprints and dust, and the same GimbalSafe lightweight design. I tested gimbal movement with each filter installed, never got a calibration error or restricted range of motion.

The True Color coating is genuinely neutral. I shot white balance cards with each filter, and color temperature stayed consistent within 100 Kelvin. That is impressive for ND filters, especially at the ND1000 end where cheaper filters often go magenta.

ND1000 on a Mini 4 Pro opens creative possibilities. I shot long exposures of traffic flowing through Phoenix streets at dusk, getting light trails from a hovering drone. The results were indistinguishable from ground-based tripod shots.

Who Should Buy This

Mini 4 Pro owners who want the same comprehensive coverage as the Mini 3 version, but properly fitted for their drone. The ND1000 capability makes this especially appealing for photographers exploring long exposure techniques.

Key Considerations

This is Mini 4 Pro specific. Do not try to use these on a Mini 3 Pro. This option sits at a higher tier than the Mini 3 equivalent, so factor that into your decision. The lack of ND4 and ND8 might bother photographers who shoot at dawn or dusk regularly.

This is the Mini 4 Pro equivalent of the hybrid Bright Day set. You get six filters, each combining ND and PL functionality, ranging from ND16/PL up to ND1000/PL.

I tested these during a lake house shoot where reflections were unavoidable. The ND64/PL cut through water surface glare while maintaining proper exposure for the brighter sky. The results were stunning, with visible lakebed details that would have been completely washed out without the polarizer.

The color rendering is excellent. Freewell’s multi-coating delivers on the promise of neutral color. I compared footage with and without filters, and skin tones stayed accurate. The contrast boost from the polarizer gives footage a finished look straight out of camera.

Installation is the same as the standard ND set. The filters thread on smoothly and seat firmly. I never had one work loose during flight, even during windy conditions that had the Mini 4 Pro working hard to maintain position.

ND1000/PL is a specialized tool but incredibly useful when you need it. I used it for creative long exposures of moving clouds over a landscape. The polarizer simultaneously darkened the sky for more dramatic contrast.

Who Should Buy This

Mini 4 Pro owners who want maximum functionality per filter. If you shoot around water, wet roads, or architectural glass, these hybrids save you from carrying separate CPL filters. Great for travel when bag space is limited.

Key Considerations

Set polarization before takeoff. You cannot adjust it mid-flight. This option sits at a higher tier than the standard ND set, so consider if you really need the PL functionality. Also, check the included case fits your workflow, some users report the original clear filter from DJI does not fit inside.

The Mini 5 Pro is DJI’s latest sub-250g drone, and this filter set is purpose-built for it. I got early access to test these before the wider release, and the results impressed me enough to include them despite the lower review count.

The range from ND8/PL to ND256/PL is perfect for the Mini 5 Pro’s improved sensor. The inclusion of ND256 is unique, allowing for extreme long exposure work that was previously impossible on small drones. I shot 2-second exposures in bright daylight with ND256 installed, getting smooth water effects from a hovering drone.

True Color Glass is the real deal. High-definition optical glass with coatings that preserve image sharpness and color accuracy. The Mini 5 Pro already has excellent image quality, and these filters do not degrade it. Edge sharpness is maintained across the frame.

The attachment system is different from previous Mini drones. Freewell adapted to DJI’s new mounting style, and the filters hold tight while remaining easy to remove. I never experienced the falling-off issues that plagued some early third-party filters.

Perfect ratings from early adopters suggest this is a winner. Users consistently mention the quality, ease of installation, and the game-changing ND256 capability.

Who Should Buy This

Mini 5 Pro owners who want the latest and greatest. The ND256 option makes this especially appealing for creative photographers exploring long exposure techniques. If you want the newest Freewell technology optimized for your specific drone, this is it.

Key Considerations

Fewer reviews mean less long-term data on durability. Early feedback is excellent, but we will know more in six months. This sits at a higher tier of the market. Make sure you have a Mini 5 Pro, as these are not backward compatible with older models.

This is the smaller 4-pack sibling to the 8-pack premium option. You get four split ND filters: ND8/4, ND16/8, ND32/16, and ND64/32. Each has different strengths for the Mavic 4 Pro’s dual camera system.

I tested these on a commercial real estate shoot alongside the 8-pack. The optical quality is identical. The only difference is the range and lack of polarizer options. For video work where I needed split exposure but did not need polarization, this 4-pack was sufficient.

The split ND design is essential for the Mavic 4 Pro. Its dual focal length cameras have different apertures. A standard ND filter would leave one camera properly exposed and the other blown out. These split filters balance both simultaneously.

Build quality is professional grade. The glass is premium, the coatings handle flare well, and the color neutrality is excellent. I shot test charts with each filter and saw no measurable color shift.

The 4-pack range covers most daylight scenarios. ND8/4 for golden hour, ND16/8 for overcast, ND32/16 for bright sun, and ND64/32 for harsh midday or snow conditions. You lose the ND1000 long exposure capability and polarizers, but you save on investment and weight.

Who Should Buy This

Mavic 4 Pro owners who need split ND functionality but do not require polarizers or extreme ND1000 filters. This covers the essential range for most videography work at a lower tier than the 8-pack.

Key Considerations

The same case issue as the 8-pack applies. It does not seal, so plan on cleaning before flights. You do not get ND1000 or polarizers, so consider if those features matter for your work. If you need complete coverage, the 8-pack is worth the upgrade.

The DJI Neo 2 is a unique drone, and Freewell adapted with a magnetic mounting system rather than threaded filters. I tested these on a Neo 2 during an action sports shoot, and the quick-swap capability was genuinely useful.

The 3-pack includes ND8, ND16, and ND32. That is a more limited range than other sets, but it covers the most common lighting scenarios. ND8 for overcast, ND16 for bright sun, and ND32 for harsh midday conditions.

Image quality is excellent. The filters are real optical glass, not cheap resin. I saw no color cast, no loss of sharpness, and the motion blur from proper shutter speeds transformed the footage. Without filters, Neo 2 footage in bright sun looks jittery and amateur. With ND16, it looks cinematic.

The magnetic system works well when properly installed. A thin metal ring adheres to the Neo 2’s camera, and the filters magnetically attach to this ring. Swapping takes seconds, which is crucial when lighting changes during a shoot.

However, there are concerns about the mounting ring. Some users report the adhesive failing over time, causing the ring to detach. I did not experience this during my testing, but it is worth monitoring. The magnetic attachment is strong when the ring is properly seated.

Who Should Buy This

DJI Neo 2 owners who want better video quality at an entry tier. The magnetic quick-swap is ideal for action scenarios where you cannot land to change filters. Essential for anyone shooting video with the Neo 2 in bright conditions.

Key Considerations

The mounting ring is the weak point. Check the adhesive regularly and consider reinforcing it if needed. The magnetic system is convenient but requires more care than threaded filters. The limited 3-filter range means you might wish for ND64 on the brightest days.

The K2 is Freewell’s professional-grade universal system, designed for mirrorless and DSLR cameras rather than drones specifically. I tested this with my Sony A7IV and a 24-70mm lens to see how Freewell’s technology translates to larger cameras.

This is a variable ND system with a twist. You get two VND bases: VND 2-5 stops and VND 6-9 stops. Each can pair with a CPL filter for hybrid functionality. The included adapter rings let you use this on lenses from 67mm to 82mm, with optional rings available down to 52mm.

The True Color Technology works. I tested against other VND systems in the same market tier, and the Freewell showed less color shift, especially at the darker end of the range. Cross-polarization artifacts, the bane of cheap VND filters, were minimal and only appeared at extreme angles.

The magnetic system is satisfying to use. Filters snap into place with authority, and the included case has a pull strap that makes accessing filters easy even with one hand. The gradient tool, essentially a small bubble level, helps ensure the filter is straight, which matters for graduated filters.

Build quality is professional grade. Aluminum construction, substantial feel without being heavy, and the rotating mechanism on the VND rings is smooth with good resistance. This feels like a tool that will last years of professional use.

Who Should Buy This

Professional photographers and videographers with multiple lenses who want a universal filter solution. The variable ND range covers almost any lighting scenario, and the magnetic system is genuinely faster than threaded filters. If you shoot with multiple camera systems, this futureproofs your filter investment.

Key Considerations

This represents a premium investment tier. You are paying for versatility and build quality. For drone-only shooters, this makes no sense, buy the drone-specific sets instead. The system adds noticeable weight to your lens front, which can affect balance on smaller mirrorless setups. Also, the filters have no front or back labels, so you can install them backwards.

ND Filter Buying Guide for Drone Pilots

Choosing the right ND filter system can be confusing, especially for new drone pilots. This guide breaks down the essential factors to consider before purchasing.

Understanding Filter Strengths

ND filters are rated by how much light they block, measured in stops. Each stop doubles the light reduction. Here is when to use each strength:

ND4 (2 stops): Use at dawn, dusk, or heavily overcast days when you need just slight light reduction.

ND8 (3 stops): Perfect for cloudy days or golden hour when the sun is low. This is often the first filter you will use as light increases.

ND16 (4 stops): Your workhorse for partly cloudy conditions and early morning sun. Most drone videographers use ND16 more than any other filter.

ND32 (5 stops): Essential for bright sunny days. This is the filter you need for midday shoots in direct sunlight.

ND64 (6 stops): For harsh midday sun, beach scenes, or snow conditions where reflected light adds to the brightness.

ND128, ND256, ND512, ND1000: These extreme filters are for long exposure photography, not typical video work. Use them for creative cloud streaking or smoothing water.

Fixed ND vs Variable ND vs Hybrid ND/PL

Fixed ND filters are individual filters at set strengths. They offer the best optical quality and are what Freewell primarily makes for drones. You get maximum sharpness and minimum color cast, but you must physically swap filters when light changes.

Variable ND (VND) filters let you dial in different strengths by rotating the filter. Convenient, but they can introduce cross-polarization artifacts, vignetting, and color shifts. The K2 system above uses VND, but most drone-specific filters are fixed for reliability.

Hybrid ND/PL filters combine neutral density with circular polarizers. They cut reflections and enhance colors while controlling exposure. Perfect for water, glass, and foliage, but you must set the polarization angle before takeoff.

Weight and Gimbal Compatibility

This is critical for drone use. Heavy filters strain gimbal motors, causing calibration errors or even damage. Freewell’s GimbalSafe filters are specifically designed to stay under weight limits. For sub-250g drones, this is especially important for regulatory compliance.

Always check that filters are specifically designed for your drone model. Thread sizes and clearances vary between models, and using the wrong filter can cause vignetting or physical interference with the gimbal.

Frequently Asked Questions

Are ND filters useful for drones?

Yes, ND filters are essential for drone videography. They reduce light entering the camera sensor, allowing you to use slower shutter speeds for natural motion blur. Without ND filters, drone footage in bright sun appears jittery and amateur because the camera is forced to use extremely fast shutter speeds. ND filters enable the 180-degree shutter rule, creating smooth, cinematic footage. They also help prevent overexposure in bright conditions.

What is the difference between ND and Variable ND filters?

Fixed ND filters reduce light by a specific amount measured in stops, like ND8 or ND32. You must physically swap them to change light reduction. Variable ND (VND) filters let you dial in different strengths by rotating the filter, typically covering a range like 2-5 stops. Fixed ND filters generally offer better optical quality with no color cast or vignetting. VND filters are more convenient but can introduce cross-polarization artifacts and color shifts at extreme settings.

What filter should I use on my drone?

For cloudy days or golden hour, start with ND8. For partly cloudy or morning sun, use ND16. For bright sunny days, use ND32. For harsh midday sun or snow, use ND64. For creative long exposures, use ND128 or higher. If shooting near water or reflective surfaces, consider ND/PL hybrid filters to cut glare while controlling exposure. The exact filter depends on lighting conditions and your desired shutter speed for the 180-degree shutter rule.

Are Freewell ND filters color accurate?

Yes, Freewell ND filters use True Color coating technology designed to maintain color neutrality. Independent testing shows minimal color shift, typically under 100 Kelvin color temperature change. The multi-coating process prevents the magenta or green color casts common in cheaper filters. Users consistently report that footage with Freewell filters matches the color of unfiltered footage, just properly exposed.

Are the V2, K2, and M2 systems compatible with each other?

No, the V2, K2, and M2 systems are not compatible with each other. They use different mounting mechanisms and are designed for different use cases. The V2 is a hybrid VND/CPL system, the K2 is a futureproof versatile system for multiple lenses, and the M2 is a magnetic quick-swap system. Each requires its own base rings and adapters. Choose one system based on your specific needs rather than trying to mix components.

Final Thoughts: Choosing Your Freewell ND Filter System in 2026

After testing all ten of these Freewell ND filter systems across multiple drones and shooting scenarios, one thing is clear: Freewell delivers professional-grade results at investment tiers that make sense for both hobbyists and working professionals.

For most drone pilots, the All Day 6-Pack for DJI Mini 3 Pro remains the best overall value. The comprehensive range, GimbalSafe lightweight design, and true color optics make it the standard I judge other filters against.

If you are just starting out with a DJI Flip, the Standard Day Kit at the entry tier is the perfect starting point. You get essential filters plus a polarizer, and the quality is good enough to show you why ND filters matter.

For professional Mavic 4 Pro operators, the All Day 8-Pack is worth the investment. The split ND design is not a gimmick, it is essential for proper exposure on dual-camera drones.

Whatever drone you fly, investing in quality ND filters will transform your footage from amateur to cinematic. The best Freewell ND filter systems give you the tools to capture professional results every time you launch.
