Are the NiSi Jetmag FSNDs Pro Enough?

Apr 2, 2025

1 stop away from greatness.

Functionality

These feel good to handle, the magnets are strong, a bit nervously so, and swapping back and forth is so much more convenient than the past NDs. Most importantly, you don’t need to keep them in a bag and can now just keep them in your pocket as they stick to each other so you don’t need to worry about them getting scratched up. The previous bag was larger than a vmount battery and could not fit in my camera bag so this is a very welcome improvement. It’s also useful that there is a 75-95mm filter ring so you don’t need to buy two sets for your 77mm lenses.

These are very comfortable to carry around with you.

Much smaller footprint than the previous FSND bags

You can either get another front/back magnetic lens cap to hold the NDs or this caddy bag, I don’t think you need both.

This hook is very useful so you can carry your NDs without hands or pockets. I’m probably returning mine because a front and back cap is easier to transport and secure enough.

The locking mechanism is quite misleading. It’s more of a blocking mechanism that simply has a hook blocking the NDs from coming off, but there’s nothing to stop the NDs from twisting out of the blocked position. Still, the magnets work well enough that I doubt you’d need the blocking feature. But it does end up being more of a nuisance when trying to attach or take off NDs. I only care about NDs so I didn’t bother buying any of the other filters, which have color sorted tabs to differentiate between them. However that means that each stop of ND won’t have any distinguishing features other than text making it hard to easily identify which one you need.

(B)Locking mechanism can block the magnets.

The locking mechanism has no secure click, you simply twist and position the lock in front of each other to block it from falling off. This isn’t particularly useful, luckily the magnets are strong enough that you shouldn’t worry.

Markers are a bit hard to read and the color tabs only distinguish NDs from other fllters like CPL and mist.

A significant reason for the cost are the high quality magnets. They are really quite strong and difficult to pull off. That means each cap will be over 30 USD. The problem is you’ll probably need at least 2 front caps for your secondary lenses because you don’t want to be twisting off the Jetmag ring just to put your normal lens caps on, which won’t fit over these proprietary threads. So yeah, functionality is very convenient! …for a fixed ND system…

Remember when NiSi gave 3 lens caps for free? Now I know why…

Pretty solid quality overall, metallic and sturdy.

Performance

I’ve spent quite a lot of money on ND filters now. I typically stick with NiSi because they’re good value and performance. However, I’m not super enthusiastic about these Jetmag Pro. They’re more convenient now with the magnet and lock system, but unfortunately there are a few missing stops for the 95mm version, most critically the 1-stop ND. This basically means these fixed NDs totally concede the fight for convenience over VNDs, as not being able to adjust 1 stop means that you can’t make small adjustments, which is a shame because they are good enough to stack without losing color accuracy.

But even if there were a 1-stop, these Jetmag seem to have inconsistent color shifting like the original FSND. The 2-stop and 3-stop are okay but the 4 has a noticeable red shift, all slightly shifting in different directions like the Swift 1-5 VND does. I suppose it will depend on your standards. You could argue this small shift is negligible, but then why not use a VND, which will always have more convenience than fixed? If I’m using fixed NDs, I want them to be vastly superior in color shifting to outweigh VNDs. So it’s up to you to decide if this amount of color shift is negligible. (the shift is more apparent full screen)

UPDATE: I bought a second set just to check if there is color shift variance in quality control. It was very marginal, so expect consistent results to what you see here. 3 is near perfect, 2 slightly green, 4 slightly saturated and red.

Final Thoughts

These are considerably more expensive than the FSNDs. Just like the Tribex, I hate how products improve upon one thing but compromise in another way. I now find it difficult to recommend these considering the price and the fact that there’s only one more 2 and 4-stop ND than the original FSNDs. If they come out with a 1-stop for the 95mm version that would be enough to change my mind.

I have no affiliation with NiSi.
