I have used ND grad filters for years on my SLR and DSLR cameras. I love scenery photography as opposed to portrait so always looking to sort out the difference in the light between the horizon etc. I live near the sea les that 300m away and walk along the cliffs regularly and don't take my DSLR with me when walking the dogs but always have my iPhone so any unexpected scenes are normally captured using the iPhone. This ND grad filter will come in useful. It fits over the lenses of my iPhone and helps sort out the difference in the light. Once clipped on it is easy to rotate the bezel to the setting you want using your finger. You have to ensure that you do not go past each of the stops or you will get leakage. SO my advise is to check before shooting that you are at the required stop. The other great thing about this filter is that it unscrews from the clip holder and can be screwed onto my 52mm lenses..Bonus... All in all this is a great little filter that I will carry around with me when out walking the dogs. We have a dog walking bag which has Poo Bags and drinking water etc so it sits in the side pocket of the bag in its case. so it is always there if we get a lovely sunset or something really nice to photograph on the sea or beach.. Get little gadget well worth the money highly recommended... As soon as we get anything really nice I will update this with the images...

Nicely built. Sturdy for a boom arm application with a small dslr. I'll buy another.

The filter I always stack are CP and ND, and now I finally have them in 1 filter!
ND and CP effects are both very nice, and the filter is built solid.
K&F makes some really nice stuff.
All threads are smooth and the filter is easy to install and adjust.
It's been on the front of my favorite lens since I got it, and it makes my vids look professional.

I already knew K&F Concept from my passion as a DSLR photographer, where I rely on several filters from the manufacturer. I am all the more pleased that I have the opportunity to test suitable ND filters for my recently purchased Mini 3.

In addition, there are several spare propellers (which I hope never need) are included.

A total of six filters:
- ND4
- ND8
- ND16
- ND32
- ND64
- ND1000

are waiting to be used. All of them are produced to a high standard and are a perfect fit for the gimbal. Over time you will also get a rough idea of ​​what ND value to use based on the prevailing lighting conditions.

The best filter I've ever tried. Unlike the other filters I've tried, the image from a DSLR actually looks like film.

I'll start by saying that, for what it is, this product is pretty good; be aware this class of device (variable ND filters) have built-in limitations.
First the good parts: the product feels solid, the knurled ring is useful for getting it on and off, and its minimum and maximum filter settings are clearly marked. I will take K&F at their word the spill-resistant coating works; it definitely does not seem to accumulate fingerprints.
Then the built-in issues: the big one being the blotchy, uneven filtration when you close it down too far (the dreaded "X" effect). On my camera (Sony A7iv with 24-105mm lens) this occurs at roughly six stops of filtering. Your mileage can and will vary, but expect to see the X at some point, especially at the wide end of a zoom. Another problem is the "roughly" part -- the markings on the filter do not necessarily correlate, at all, with F-stops as metered by the camera. They are at best approximate. A third problem is the Min/Max zones are marked but there is no tactile feedback or detent to tell you when you exceed them.
More expensive ND filters may not have these problems but they definitely come with a pricetag. If this filter works OK on your camera and lens and you can live with the limitations, go for it.

This is my first variable ND filter. I have to use it for my video needs. It is a solidly built filter with reusable packaging for storage. For the price, I love it for shooting videos. Especially on bright days when I'm in focus, this helps give my videos a bit of atmosphere and focus on the subject. Can't speak to photos as I haven't had the opportunity to take this out for landscape shots. If I do, I'll definitely update. For the price, I find the 10 Stops to be a great addition to my on-the-go gear for video needs.

I hope this review or even just the pictures were helpful in your purchase decision or not.

The helpful feedback will be greatly appreciated. Cheers buddy!

Love it.I was worried that due to it being light that it would be flimsy but no it’s very sturdy and built with quality. I have a dslr camera but use my iPhone most of the time. I love that it can hold my phone. If you enjoy making videos I definitely recommend. It’s very portable as well it fits in my backpack perfectly.
