Set and forget. It won’t bother you anymore. It should do the job protecting my lens.

The big advantage of this filter is that it can remain on the lens of the DJI Osmo Pocket 3 because it is very thin. I have had some filters before that I had to take off every time I turned the camera off. This is not the case with this filter. It sits very firmly. The magnet power seems to be sufficient.

Nd looks decent.
Magnet holds very good.

Makes very soft edges around in photos or videos. Specially in hard sun.
Bit annoying,
But overall ok.

This is exactly what I needed to accomplish having the diffusion look with an ND filter using only one product on my Osmo Pocket 3. No need to stack filters. I love it. Only thing I wish were different was that the magnetic attachment was stronger so when adjusting the ND it didn't feel like it was about to fall off. I think they did the best the could under the circumstances and I am impressed. Thank you!

It may not be the best filter on the market compared to the references in the field, but since it is a camera intended to film "quickly and well done"; it is very practical by simply turning the ring until the desired ND index. On the other hand, the white reference point is very small .... The results, even in Auto mode, are very satisfactory.

The ND filter is good and does its job magnetically allowing it to be kept on the nacelle even when turned off being thin but it would have been good to have notches on the adjustment.

After using it for close to a month, I found this to be a budget friendly but very good quality black mist with variable neutral density filter for the DJI pocket 3.
The construction is quite good but not premium. The filter itself is made of glass with multiple coatings. In a month of intermittent "not so carful" use, there was no scratch. The glass filter has a little play in the housing and not quite as snug as I expect. Rotation of the glass filter is also loose without sufficient damping. The filter fits perfectly on the pocket 3 and the magnet holding the filter to the lens is quite strong.
Mist filters have become a popular tool among photographers. The mist effect on this filter is not very strong; there is a soft glow around bright objects, and softening of contrast and texture, which are the intended effects. The neutral density provides up to 5 stop reduction in exposure, useful in high contrast shots or very bright beach scenes. Haven't had the opportunity to try it on snow scenes yet! There is no polarizing filter.
There is no evidence of chromatic aberration.
The filter comes in a large protective case although most DJI pocket users tend to keep their filters in the neat filter slot in the hard case that came with the camera.
A screen protector is included in the package but I did not use it.
All in all, this is a decent black mist filter with a 5-stop neutral density filter that is well built. If you're looking for that black mist effect or need a neutral density filter for the DJI pocket 3 (this will not fit on a pocket 2!), it is a good choice.

As a previous user of some packs that contain multiple ND filters, having this adjustable one is just so much more convenient.

The magnet is very strong, no risk of it falling off and the profile of the filter is thin enough that it doesn't get in the way. Works just as well as the other separate ND filters I have

Great ND filter with Black Mist

This is great. Ideal for the Osmo Pocket 3.

Comes in a very well padded case and with the screen protector which is a nice bonus. Fits perfectly and magnetically over the camera lens. And it’s perfect for protecting your lens too because that’s something that scares me with the osmo so this offers peace of mind.

And the filter is great. Nice variable ND gradients. Only little negative is that because it’s so small it’s quite tricky to adjust the ND accurately. Very delicate hands needed (or a bit of fiddling) might be an issue if you’re working at speed in varying light conditions but not an issue for me. Performs well and very good value.
