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 Circular Polarizer and Neutral Density Filter offers the convenience of two quality useful filters in one, at a reasonable price.

The neutral density filter provides between 2 to 6 stops of light reduction, more than enough when wanting to slow your shutter speed for video or specific type of photography, like waterfalls.
Similarly, the circular polarizer removes glare and enhances color and contrast.

Although the filter did not come with instructions, using it is easy, and the outer rim of the filter is clearly marked to indicate the amount of light reduction. Turning clockwise changes ND levels, and counter clockwise is the circular polarizer.

The rotation of both the ND filter and circular polarizer is smooth and even, and the frame, which is made of aluminum alloy, is well-machined and screws easily into the lens. Overall, the filter appears very well made and it even comes in a very nice (leather looking) carrying case.

Bottom line, this is a very useful and convenient filter to have in your kit. Content creators of all types, video and photos, will appreciate the ability to reduce light for video and different types of photography, and increase contrast and color vibrancy.

Highly recommended!

Best camera for the price. This camera is much smaller than those I used, but the video quality is great.

I am getting older so this kf concept Basic monopod allows me to cover some of my B-roll DSLR video needs without lugging a full tripod all the time. You have to do your part vis-a-vis remaining still, but this was well worth the price.

Best quality filter I had in a while,

I use this filter for video to get the right shutter speed regardless of the aperture. A variable ND filter is of course perfect for this. I can't see any loss of sharpness or similar, but as expected there is a slight, hardly noticeable color cast, which you can easily correct - if you want - on the camera.

I'm using this on a Fujifilm telephoto mainly for video. Image quality is very good with no aberrations, relatively easy to screw/unscrew, hard protective case. Recommended for those looking for a good quality fixed ND filter.

I just got back into photo mode. So the new DSLR setup. I've never used an ND filter before. I'd like to try that. This filter does what it is supposed to. As a newbie to ND filters, I think this is a good build quality.
