I lost my original osmo wide lens so needed a new one. I tried this and so far so good! Perfectly packaged and fit and finish. No issues so far

I want to start by saying that I am not a photography expert. I have the Osmo Pocket 3 and I know how to use it basically. I did purchase the creator combo which comes with the wide-angle lens. I chose this because I wasn't sure if there would be a difference in how wide the angle would be in comparison to what I already have, as I don't understand all the various terminology they use for lens. Keeping that in mind, I did not see a noticeable difference when I tried switching between both of these lens. Personally I like the build of the DJI lens better, and you can see a noticeable difference between the two when they are side by side. But the functionality of the lens is very comparable to each other. I also do not like anything on the outside of my lenses or filters, and this one does have white writing with the brand on it as compared to the clean, blank facing of the DJI branded one. They could put this branding on the outside edges to keep that from being so noticeable, but perhaps that is too difficult? These are also comparable in size with this one being ever so slightly larger in height when side by side. I think the overall take away from this review should be this - if you need a wide angle lens for your Pocket 3 and you did not get the creator combo, then this would be a more affordable solution.

K&F Concept Magnetic Wide Angle Lens Compatible with DJI OSMO POCKET 3, Wide Filter External Expanded View Lens
There is a mark/damage and dust in the layers of the lens. This looks like it would have happened in the assembly of the lens as it is inside the layers of the lens. This makes it useless to use.
The lens was replaced and all is good with the new lens. Good after sales service.

First off, yes, they fit well and are low profile enough to allow the Osmo to shut down correctly, without blocking (unlike the Osmo wide angle lens). The photo shows the Black Mist filter fitted, with the Osmo in the 'off' position.
The quality seems good and they come with a secure, padded case.
You might want a stronger ND filter for very bright conditions, but this set is a great value set of filters to give your videos a better look.

The image gets dostorted both on the upper side as well as the downer side. I will add an example soon.
This happens mostly when the object is close by, when is far away is not so visible, for example the horizon remains pretty straight, but at tall building is quite visible.
I like that the image quality remains quite good, the edges maybe a bit blurry but not so significant to notice for video.
Also good that you can actually snap it to the case like the original wide from DJI, I don't have that lens to compare it to to see the difference which would help to make a better decision of this one is worth buying, however for the price difference I think it is worth it and that is why I kept it.
UPDATE:
I added an additional star because of the great customer support. The company reached out to me to compensate on my review and I appreciate this kind of customer support by any company who concerns about their products, the feedback will help them improve further their product. Glad to see such support to customers!

Great product! These ND filters feature a sleek, slim design. I love them! Initially, I had an issue as they left flares and rainbow artifacts in images, as demonstrated in my photo. However, I later found that this was due to the screen protector I had. Once I removed it, the artifacts were gone, and I now have perfect images with these ND filters.

One of the best things about these filters is that they are thin enough that you can allow the camera to close with them still on. You can't do that with DJIs filters, which I also have. The magnet is strong so they don't fall off easily. These filters are high quality. They help in varying outdoor situations. I'm not a pro so I can't provide a proper breakdown on that area, but I can say they are a good addition to my Pocket 3 accessories.

I highly recommend this lens for the DJI Osmo Pocket 3. It's a great add-on for such an already amazing camera. Would've given 5 stars but my only dislike is the lens is bulky and the Osmo pocket 3 cannot shut down properly due to the size of the lens. I would prefer a thinner design like the K&F Concept ND Polarized Filters. I'm able to power down the Osmo Pocket 3 with those filters on the camera. This Anamorphic Lens is well built and produces cinematic style shots that look professional.

The specific set I obtained, containing the CPL, 1/4 black mist and ND2-32 covers so many bases that it would be difficult to come across a day where I need more.

I used the black mist filter extensively for night filming on holiday, the black mist softens the brighter lights which can appear harsh due to the camera having to ramp up the exposure.

The CPL removes glare and reflection from water and glass, again really good for shoreline and beach filming.

And the VND, all the way from 2-32, covers a significant portion of a bright day.

You also get a bonus screen protector.

I have recently started shooting a lot more video using anamorphic lenses, both cinematic lenses on my camera and mobile lenses on my iPhone.
The ming link was my Osmo Pocket which given the excellent video it produces was shouting out for such a lens.

Whilst 1.2 is ne to me as I generally shoot 1.33 I am still more than happy with what I am getting from this , Resolve takes on Desqueeze duties.
Video is a little soft but I am still getting to grips with this and feel some of that may be my technique on this tiny form factor, I have no doubt that with practice I should be able to produce more than acceptable results.
