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 82mm Circular Polarizer Lens Filter is a fantastic addition to any photographer's kit. It significantly reduces glare and reflections, ensuring vivid colors and improved contrast in your shots. The build quality is solid, and the ultra-thin design prevents vignetting. While it's a little more expensive than some alternatives, the multi-layer coatings make it worth the investment.

have been a fan of K&F Filters and many of their other photography products for some time and have come to appreciate the brand's consistency and quality. Most of my lenses live their lives with a K&F Concept UV protection filter on the front. I have sufficiently tested the transmittance and sharpness of K&F filters in the past that I now consider them a trusted brand. I am confident in their quality. And that's the point, right? Find a supplier you can trust to deliver exceptional quality. I use polarizing filters extensively, much more often than not. They are a multi-purpose filter that allows the user to add contrast and saturation, reduce glare and reflections, and to some extent, since they add neutral density, control exposure. There is little reason not to use them, except in low light situations. Another benefit of the 82mm size, and most sizes for that matter, is its cost advantage. The use of step-up rings allows it to accommodate a range of lenses that require a smaller filter size. This applies to filters of any size. In practice, the K&F Concept 82mm polarizing filter can be used on lenses with filter sizes from 77mm upwards, provided appropriate adjustment rings are used. You do not need to buy a separate polarizer for each of your lenses. The filter is solidly constructed from aircraft-grade aluminum and is typical of the high quality of K&F Concept filters in general. The damping of the outer ring is even and provides the necessary resistance to keep the adjustment securely in place. Since a CPL has no stop, when adjusting it it must be rotated in the same direction that you would attach it to avoid accidentally detaching the actual filter from the lens. K&F Concept uses AGC glass, formerly Asahi Glass Company, a Japanese company that is the largest glass manufacturer in the world. They also claim that there are 24 multi-layer anti-reflective coatings on each side of the glass, which are important for reducing internal lens reflections. In my testing, the filter lived up to the seller's claims. It polarizes light and the colors seemed "true," or at least to the extent inherent in the rendering capabilities of a digital sensor. This was affected by camera settings and the sharpening and dynamic range features introduced by the manufacturer. In other words, "True Colors" is subjective. Also, I did not notice any reduction in sharpness when using the filter. The physical properties of the filter are its relatively light weight, as well as the faceted chinas around the perimeter of the polarizing ring, which provide a better grip. I use an 82mm VND filter, which is 82mm in diameter, and the thread on the front of the filter, also 82mm, provides enough depth for the stacked filter to be securely attached. The K&F front lens cap that comes with the filter is on par in quality with any OEM lens cap I own. The clamping levers are easy to use, firmly spring loaded, and give a firm grip to the filter or the lens it is attached to. I also appreciate that the front threads on the CPL match those of the 82mm filter size, allowing the use of standard OEM accessories such as a lens protector. The filter comes with the lens cap, an adjustable lanyard, a high-quality microfiber lens cleaning cloth, and a plastic storage case. K&F Concept offers good value for money and doesn't cut corners.

tested this 82mm polarizing filter for photo output on different lenses, natively or via step-up rings. It screws on and off without any problem as long as it is not at an angle. I have put it on and removed it a good fifteen times without the slightest problem, so the filtering is good. As with any CPL filter of this type, there is a rotating part to adjust the intensity. The thickness is conventional, the grip is very good, the optical treatment too. The 82mm lens cap is a big plus, especially if, like me, we use a filter on several lenses of different diameters, it holds well. The mini lanyard that comes with it probably won't be useful, I don't know anyone who leaves their cork hanging on the end of the lens anyway. And as a bonus, it comes with a microfiber cloth, I have dozens of them but they are of high quality so it is always welcome. For €48 at the time of this review, we have a CPL filter that falls between the entry-level and the pros, but this model still does the job perfectly.

It's pretty amazing to me that you can get an 82mm UV filter with 18 layers of coating for only $20. As far as I can tell, there is no loss of contrast or color shift. If anything, you may experience different reflection patterns at certain angles (which I'm a fan of) and will experiment with that. A UV filter not only protects your lens, but also makes the front element waterproof. And if you've had a chance to play around with magnetic filters before, it works just fine with those too. I plan on buying a few more of these so I always have them on my lenses so I can swap/stack my other magnetic filters in seconds. Highly recommend!

Small kit including an 82mm UV filter, an 82mm lens cap and a small elastic band for the lens cap. When I go for a photo walk with friends in the countryside/forest, between branches that can come back in boomerang, brambles and other thorny vegetation or just dust, tree resin or other, as an amateur who does not necessarily have the means/desire to insure or especially replace his equipment, I appreciate knowing that the front lens of my lens is protected. Whether on my 30 Mpx camera or the 24 Mpx camera, even with my pricked Laowa Macro 100mm, in 95% of cases there is no significant visual impairment between with and without the filter. Of course, for landscape, portrait or studio shots as a professional with much more expensive equipment, my point of view would have been different. But as an amateur, the negligible impact on sharpness is largely offset by the increased protection. The lens cap is also more than welcome, classic plastic construction, very good. Even though the original lens cap fits on the filter too, the cap is suitable for creative filters with a support ring on lenses of different diameters. I can't imagine using the little strap, at least not to keep the lens cap from dangling on the lens itself. I find that even more annoying than anything else about the lens cap. For €18.40 at the time of testing, the kit is very good.

A decent ND1000 82mm filter provided with an excellent carry case.I found this filter excellent when properly screwed on to my lens, vignetting was visable when not properly fitted. It is quite shallow which also helps here.Shots displayed are taken with Nikon Z6 & 14-30mm S line lens I had to stop down to F10 for 20secs & F13 20secs both shots ISO 50 to avoid blowing out the sun, shadows recovered in post processing.The filter was very easily wiped clean after being splashed by a wave, I think the coating definitely helped here.I am quite pleased with the product its defintely much better than my old 72mm

I ordered this K&F Concept 82mm Variable Fader ND2-32 ND Filter and CPL Circular Polarizing Lens Filter to reduce the number of items I carry with me on a landscape shoot.

When shooting landscapes, a neutral density filter can come in handy. It's the easiest way to create that smooth water effect for waterfalls, rivers, and other moving water. And, a polarizing filter helps to tame reflections that would otherwise detract from your images. This filter from K&F combines these two types of filter into a single screw-on attachment.

I ordered this is the 82mm size (so that it would fit my largest lens) and I'll use step rings for smaller lenses. Operating is pretty easy. You use your fingers to rotate the CPL and you use the attached knows to rotate the variable ND filter. Based on meter readings, you'll get about a 6 stop reduction in exposure when the ND filter is set to max and the CPL is adjusted. With the ND set to minimum, you'll see about a stop and a half or so of exposure reduction.

I did not notice the X pattern that appears so frequently with variable ND filters. However, that tends to happen more with wide angle lenses, and a friend is using mine so I wasn't able to test that out. Color rendition is pretty neutral. I did not notice any reduction in sharpness, nor did I experience significant flaring. Unfortunately, it's not possible to use a lens hood when this filter is attached. Also, you need to know that the front diameter of the filter is greater than the rear diameter. For example, if you order the 82mm version of this filter, your 82mm lens cap will not fit. Instead, you'll need an 86mm lens cap. Be sure to look at the chart in the listing so that you know what specific size of lens cap you'll need for the filter size you purchase.
