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...

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’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,

Best quality filter I had in a while,

I purchased this grad filter for shooting cars in direct sunlight. I got exactly the effect I was looking for. The car properly exposed with the sky not blown out. This filter is of high quality glass and the mount system is well designed without being overly complex.

I bought this ND filter kit as I had good experience with K&F (the tripod is brilliant) and was looking for a system that would work with all my lenses. Firstly the quality of packaging and storage is extremely high, the glass comes in its own case keeping it clean and safe. Second, it's very easy to set up and use (a bit fiddly if your hand is cold) and third, the image quality is great, there's no color cast (the colors you see in the images above are my edit, not the error. ) of the ND filter) and it allowed me to blur the water and clouds in the middle of the day.

I am using this K&F Concept ND Filter for my sony alpha a6000 with kit lens. product quality is very good but unfortunately it doesnt seem to fade properly with the kit lens I have. Check out the picture. Maybe I dont know how to use this filter. Any advice? I have given this product 4 starts only because of the quality of the build.

High quality glass with excellent ND filter performance. Turning the filter too far will not have an "X" due to the hard stop built into the design.

The kit includes a magnetic adapter ring that screws onto your lens and acts as a mounting tool for the ND filter - just toggle it on and off whenever you want. very pleasant.

It is important that the filter itself offers a wide range of densities with minimal color shift.

The slim design is great and does not cause vignetting with regular use.

Overall, a great filter will deliver consistent and reliable results.
