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

So easy to use, just put it on the lense and you're ready. Really impressive. You can get in much closer, macro video looks great. You notice such a difference once you take it off the lense. The Osmo on its own can get no where near as close.

Whilst I use the Osmo primarily for video, on occasion I do take the odd photo and my wife, who has a fascination for creepy crawlies has been known to grab whatever camera I have to hand to snap some rare bug or other.
This just builds on what is already a remarkably good device, it mounts easily through magnets and isn't easy to dislodge, and does what it promises to do.

A single caveat, unlike filters this can't be on the Osmo when you turn it off as it is too bulky to allow the gimbal to close correctly.

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.

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!

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.

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.

I did post a review before with a video to show the actual quality, but for some reason kf congcept won't allow it.

So I'll just say that this is a really well made, solid lens. There's a lot of glass and you can feel it in the weight.

The focus range is 20-40cm so you get a real close up with this. For me it's going to be ideal for showing close ups of products in products reviews and also for some flower photography I'm planning to get into.

I think it's excellent value for money and it's typical high quality that you get from K&F. It attaches securely - magnetically of course - to the Pocket 3 and it stays in place. There's no wiggling about. Very impressive item.

The Pocket 3 is not something I would have thought of to use when it comes to Macro photography, but this filter definitely helps me get really close up shots for sure. The filter is very well made, and attaches easily magnetically to the front of the camera lens. Everything seems very detailed, and the magnification is pretty impressive. You do have a little bit of distortion on the sides, however, but that is any macro lens, so this can only be used for specific close up shots. Overall, I am pretty impressed with it.
