NISI JetMag Pro
Hands-on review of this exciting new magnetic filter system!
Let's talk filters. As photographers and videographers, we know they're essential tools for controlling light and creating stunning images. Circular polarizers (CPLs) cut glare and boost contrast, while neutral density (ND) filters allow us to use wider apertures or slower shutter speeds in bright conditions. If you’re one of those camera juggling creatives who needs to be in total control of the subject at all times, you simply can’t do without these essential tools.
For years, my go-to filter system has been the Nisi V6 Pro. It’s a workhorse set of lens filters, designed to cater to every shooting scenario. It comes along with me on every serious shoot. The image quality of NISI filters is superb, and it's incredibly versatile. But nothing is perfect and V6 Pro is no exception. Its versatility is also its flaw, being a multi-part system: lens adapter ring, filter holder, chunky filter case and the 100x100mm or 150x100mm filters themselves. It’s a lot to carry. Swapping the square filters isn’t the fastest process and there’s a significant risk of dropping and breaking the filters. While fantastic for serious landscape work, it’s not exactly the most travel-friendly setup, especially if you're trying to pack light.
NISI V6 Pro Filter System with 100mm square filters and Circular Polarizer
The NiSi V6 Pro filter system is a fantastic piece of kit, but it hit a snag with my Fujinon GF30mm T/S lens because of its weird 80.5mm front thread. That oddball size only works with Fujifilm’s own lens hood and a 105mm circular filter adapter, which is a pain because those filters are huge, pricey, and not something most photographers (including me) have lying around. But anyway - this is not a review about the V6 Pro.
First of All, Why are Screw-In Filters Better Than Square Filters (Especially for Long Exposures)?
Screw-in filters are a better choice than square filters if you want hassle-free reliability. Their threaded design screws right onto your lens, creating a snug fit that blocks light leaks completely—no gaps, no fuss. This is huge for long exposures over 60 seconds where even a tiny light leak can wreck your shot. Square filters, on the other hand, need a holder and adapter ring, which can leave room for light to sneak in if they’re not perfectly aligned.
Screw-ins also save time and space. There’s no fiddling with adapters or bulky holders—just twist and go. Perfect for fast-paced shooting, like chasing that golden-hour light. They’re less likely to cause vignetting on wide-angle lenses, too, since they sit flush against the glass. Plus, their metal rings make them tougher for travel compared to delicate square filters, which feel more exposed (literally).
If you’re doing super long exposures or shooting in tricky conditions (wind, rain, etc.), screw-ins just make sense. No light leaks, no shaky setups—just consistent results. They’re not as flexible as square systems for stacking filters, but for pure reliability? They’re the way to go.
NISI JetMag Pro
Enter Nisi and their Jetmag Pro magnetic system. Thankfully, NiSi actually listens to their customers, and they came through with the JetMag Pro system. They even produced a specific adapter for the JetMag Pro that fits this odd 80.5mm thread, which is a total lifesaver. This magnetic filter setup skips the need for those clunky 105mm filters and works seamlessly with lenses like the GF30mm T/S, even with its funky thread. It’s a perfect example of NiSi solving a niche problem without cutting corners on quality or usability. No more workarounds or DIY solutions – NISI has provided a proper, professional filter solution. Plus, they included an 82mm adapter for the rest of my lenses which make the system even more useful.
The kit comes in a nice, compact grey textured case with bold yellow branding and a sturdy zipper. It’s small enough to fit comfortably in a single lens compartment of my camera bag. Inside, you get the two lens adapters (one for the TS 30mm and the 82mm), plus a set of ND filters (3, 6, and 10 stops) and a True Color CPL. It's clearly designed with run-and-gun cine shooters in mind, but I’ve found it incredibly useful for my still photography, especially architecture and landscapes.
What makes the JetMag Pro so brilliant is its portability and ease of use. The filters are incredibly thin, and the magnetic system is fantastically intuitive. The filters snap into place effortlessly and a small twist locks them securely. No more fumbling with screws or holders! This is the first time I’ve used a magnetic filter system, and honestly, I am hooked. The speed and convenience are just too seductive. Filters are made from aircraft grade aluminium. They have a wonderful satin finish; they are very thin and super light. I don’t know how NISI engineers integrated the magnets into such a thin frame, but they did, and the locking mechanism works effortlessly.
As you’d expect from Nisi, the glass is top-notch. They use high-quality optical glass with advanced coatings, guaranteeing exceptional image quality. They're also water-repellent, which is a huge plus when you're shooting in less-than-ideal weather. This is the type of quality that’s consistent with every NISI filters I’ve used so far, and come to expect from them.
One more thing that really impressed me is the inclusion of magnetic front and rear caps for the filters. These are made of aluminium as well, have a very thin profile and provide excellent protection whether the filters are stored in the pouch or mounted on the lens when as protection cap. It's a small detail, but it’s a very nice touch and shows the attention has been put into this system.
Of course, all the clever design in the world is useless if the filters don't perform. So, I put these to the test in the field, and I'm happy to report they did not disappoint. The ND filters maintained excellent color neutrality, with no noticeable color casts. Image quality and color rendering remained faithful to the scene, and I didn't observe any image degradation or vignetting, even when stacking filters. It's clear that NISI has taken image quality very seriously with this product. To demonstrate this, I’ve included some sample photos.
The first image was taken without any filter. The next three show the effect of the 3-stop, 6-stop, and 10-stop ND filters, respectively. Compare these images and you’ll notice that the colors and contrast remain virtually the same – it’s an impressive performance.
The above example demonstrates the effectiveness of the JetMag Pro’s Circular Polarizer. If the angle of the glass is just right in relation to the CPL, the reflection will be removed almost entirely and it comes without any cost. The sky gains a lovely deep blue tone. The colors are rendered accurately, there’s no vignette and the image is extremely sharp. I used the GFX 100 II camera with Fujinon GF 250mm lens.
In one test, I stacked multiple filters to see how they’d impact image quality. Once I hit 10 stops, there was a tiny cooling effect on colors—barely noticeable, really. But even that was a non-issue: a quick white balance tweak in any RAW editor sorted it out instantly. The real win? No vignetting or softness crept in, even with three filters stacked on all my lenses. That’s a solid testament to NISI’s high-quality glass and anti-reflective coatings. They nail color accuracy and sharpness, even when you’re pushing the limits with heavy filter layers. Seriously impressive stuff for long exposures or multi-filter setups!
The above comparison features the iconic skyline of the UAE’s capital city Abu Dhabi. The image on the left side was shot with a Circular Polarizer filter. There was approximately 1.5 stops of light loss. Exposure settings were f5.6, 1/1000s at ISO 100 and right side image was taken with a 10 and 6 Stop ND in a stack plus a CPL filter on top for a total of 17.5 stops of light loss. Exposure was f5.6, 480 seconds, ISO 100. Image quality is excellent in both exposures.
Now, there is one potential con worth mentioning. Because the magnetic connection is quite strong, pulling the thin filters away from the lens does require a bit of force. There’s a slight chance that the pulling motion could cause you to accidentally drop a filter, which, given their delicate nature, could lead to damage. So, a little caution is definitely advised when removing, or separating them when they are stacked. It’s not a biggie, but something to be aware of.
In short, the Nisi Jetmag Pro is a high-quality, convenient, and ridiculously portable filter system that comes with all the perks and zero downsides. It’s lightweight enough to toss in any bag, yet sturdy enough to handle daily abuse. With the right adapter ring, it’ll snugly fit virtually any lens—no wrestling with clunky holders or finicky setups. Mounting and swapping filters takes seconds, which is a game-changer when you’re chasing light or switching lenses mid-shoot.
What really seals the deal? Image quality doesn’t take a hit, even when stacking multiple filters. Colors stay true-to-life, contrast remains punchy, and sharpness holds up perfectly—no murky shadows or weird color casts, even with three layers of glass. That’s a credit to Nisi’s top-tier optics and coatings, which clearly prioritize performance over gimmicks.
Whether you’re a filmmaker chasing cinematic shots or a photographer battling awkward lenses like the Fujifilm TS 30mm, this system just works. It’s eliminated all the usual filter headaches for me, and I can’t imagine going back to anything bulkier or less reliable. If you want a no-compromise filter setup that’s as easy to use as it is effective, the NISI JetMag Pro deserves a spot in your kit.
