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...

It is recommended to use filters on the lens activated by screw-on filters

Bought it to replace the cheap grad filter set that gave horrible images. As soon as you open the boxes, the first thought is how well everything is presented and how high quality it is finished. All metal parts are precisely manufactured. The measuring glass is of high quality. The bag has a leather look and has a tab for easy access to the filter. The filter folder can rotate on the adapter. This is spring-loaded and can be easily attached to and removed from the adapter. Anyone looking for good quality and value for money should consider this kit.

I have loved that they are magnetic, because it is much faster to change one for another or remove them without having to screw them. I constantly wear the UV to protect the lens and when I want to subtract a couple of steps of light or there is water, I leave the CPL fixed. They have good quality and a reasonable price. I have tried the variables and there is no color ; much better these, and I forget about the vignetting. The ND 1000 is very correct also for long exposure. I miss that the magnetic metal cover does not come in the kit, in the end I bought a loose ND 64 filter, to be able to have it and I love the speed to have the camera ready.

Love the magnetic property after years of using screw on filters...this is a game changer. By no means cheap, but the build quality is excellent. I love the case that comes with the package. I didn't notice any color cast.

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,

Hello, you have to give K&F one thing, the design of the filter and the bag as well as the workmanship are 1A and I couldn't find anything particularly negative on the test images, but I still only give 2 stars. Why? 1. In my opinion, the variable gray filter ND 2-32 is poorly chosen and insufficient in terms of gradation. Many who work with gray filters use ND 8, ND64 and ND1000, for example, in order to be able to really carry out a long exposure to smooth water or people to make the moving images disappear and that is not possible or only possible to a very limited extent with the gradations from ND2 to ND32 selected here.2. The price, K&F is asking 280 euros at the moment and for this money you get a really good plug-in filter system with various filter plates incl. POL filter or a magnetic round filter system. Such systems then usually fit the entire range of lenses from 82mm screw thread onwards, while these filters only fit 67mm lenses and with a step-down ring also on smaller lenses but not on larger ones.3. For the price, it would have been desirable if you had haptic feedback on the 5 levels when you reached a level, but the filter turns buttery soft, which is very pleasant from start to finish. Conclusion: For whom can I recommend the filter? Actually only for people who don't know what to do with their money, who only have lenses with a 67mm screw thread and are too lazy to buy normal screw filters in several strengths and then change them depending on the requirement.
