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...

The K&F Concept Magnetic 62mm Lens ND Filters Kit (5 Pack) GND8+ND8+ND64+ND1000 + Magnetic Filter Adapter Ring Filters Set with 28 Multi-Coated for Camera Lens:

This is an outstanding ND filter kit. The filters themselves are very good ND filters with no color shift. I have been using several K&F Concept filters lately and I find them to be among some of the best I’ve ever used. Overall very well engineered and constructed. This kit comes with 3 levels of neutral density and 1 graduated ND. The filters attach magnetically to a screw in ring, making swapping them out quick and easy. The magnetic ring is pre attached to one of the filters when the kit arrives, and you will use that one ring for all 4 filters. I really love the addition of the gradient ND as landscapes are one of my passions and this filter is ideal for bringing drama out of the sky. The kit also comes in a very nice filter wallet with several ways to attach it to your bag, belt, tripod etc. This is such a nice touch, and it really is a nice wallet, not just a cheap holder. I highly recommend this kit if you are looking for high quality ND filters. If you love to shoot very shallow and wide open, these are a must have. Solid color rendition, well designed and well made, high end filters.

I had been hesitating between several brands for a while to choose a filter holder for ND and GND filters. I took advantage of a flash sale to acquire this kit. I am not disappointed.
the set seems robust and easy to store.
The case, quite pretty, has 5 compartments, 3 of which, for square ND filters, can be lifted by means of a ribbon. On the back of the case, there is a ring to pass a strap and a passage for a belt. I would have liked a slightly more spacious compartment to house the adapter rings with the CPL filter when it is disassembled.
The assembly (or disassembly) of the elements is well explained in a manual in several languages, including French.

Main positives:
No color cast or loss of sharpness on the first tests carried out.
The plastic frame with its tabs to handle the ND filters.
The CPL filter installation system on the filter holder.
the knurled knob for mounting the adapter ring and the rotating block of the filter holder.
The very accessible wheel to control the polarizing filter.
Firm hold of the square filter on the filter holder.
The robustness of the metal filter holder.

If you have to find some negative points:
The slightly too vigorous maintenance of the square filter in the filter holder.
the click too hard to lock the CPL filter in the filter holder.
No pouch to independently protect the CPL filter in the case.
No CPL protective cover when the assembly is installed on the lens.

have already bought several K&F square filters and the results are very good, they are good value for money. ND filters (ND8, ND64 and ND1000) are not noticeably dominant in the photos. The distribution of the 3 colors in the histogram is very similar in terms of direct camera photography, making it tremendously easier to edit photos by not having to eliminate dominants. The purple filter offers a very interesting help for night shots. Removes much of the orange halo/fog that appears in night city photography and provides a good starting point for image editing.

In addition to square filters, I have now also bought the inexpensive magnetic filter holder set. I can only say: topp. However, I lack the possibility of obtaining ND 8 and ND 64 (magnetic), because only ND 1000 and polarizing filters are available. A second glass-filled filter holder is included, which is super with adapter ring for a second lens size can be kept permanently and still! fits in the super handy case. For now, this inexpensive set with magnetic holder is enough for me; if I have further requirements, I will probably switch to the "large" filter holder system from another manufacturer (approx. 400 euros with three ND filters). Which photographer does not know this "want to have?". In short, the post on YT by Riko Best has convinced me. Would I recommend it? Yes, to anyone who wants to work with gray filters now and then.

In addition to square filters, I also bought the low-cost magnetic filter holder set. I can only say top. However, I lack the possibility of obtaining ND 8 and ND 64 (magnetic) because only ND 1000 and polarization filters are available. A second glass-filled filter holder is included, which is super durable with adapter ring for a second lens size and yet! fits into the super handy case. For the time being, this low-priced set with magnetic holder is enough for me; for further demands, I will probably switch to another manufacturer's “large” filter holder system (about 400 euros with three ND filters).

I’ve been wanting an ND Grad filter for a long time, decided to go for the K&F as all of their other items are great value for money,
I wasn’t disappointed when I tried this,
