As a rule, I do not write reviews that simply repeat the product page verbiage. That’s for you to read before you decide to buy. I am also getting away from what, where, when, who, and how of gizmos. I assume that if you are buying a gizmo, you know what it does and then decide if you can use it – for whatever.

For me, ND and CPL filters are mandatory for landscape photography in so far as they can accomplish what post-processing cannot. This pairing offers the best of both worlds in a single filter without introducing aberrations or vignetting except with wide-angle lenses. With my Nikkor AF-S FX lenses, I will get very slight vignetting with this combo or other stacked filters at f/4, 16mm; it disappears at 21mm. The vignetting is so slight that, if desired, post-processing readily eliminates it so there is no need to stop down.

I have used filters with film photography for decades without experiencing any of the alleged deleterious aberrations/effects. For me, digital photography is no exception. In fact, most photographers and authors agree that there is no data to suggest that filters introduce aberrations except for, possibly, ghosting. I have a few K&F filters and have never been disappointed. In other words, relax and have fun creating with this combo.

To some conflicting reviews.

Cannot use lens shade/cap – or – the lens cap fits fine. (Depends on . . ..)

Color shift – or no color shift. (Looks like one instance of underexposure to me.)

No stops between ND options – or – nice that there are no stops between ND options. (Food vs. poison)

So, a filter combo to afford one the ability to adjust/correct exposure in a variety of situations - for me, landscape photography. If you are a regular user of ND and CPL filters, then this combo might make your efforts a bit easier.

This is a great variable ND and CPL filter that works very nicely. It Is an ND2-32 variable and circular polarizing filter. When attached to my lens and texted through the ND range there was no notice of the "X" pattern that can be noticed in some cheaper quality variable ND filters. the ND rage is effective for general photography and should prove useful in any photography kit bag. there are two small "handles" that makes for easy rotating/adjusting of the ND range but I do prefer a design that doesn't have the handles as it's a little more compact and can be kept on your lens without worry of catching the handles if you are putting your camera in a bag and removing it frequently or quickly. That said, there is some merit to the handles as they make for smoother adjustment. It's all to your preference. The polarizer comes in a nice plastic holder with good foam to keep it safe from damage. The 24-Layer waterproof coating and 5 Stop ND Polarizer is a nice combination particularly for landscape photos. All in all this is a great variable ND filter that I wil Ladd to my kit to compliment my other filters. I would recommend it.

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.

I had never owned a K&F Concept brand filter before and was pleasantly surprised when I first used it in my landscape photography. The reverse graduated ND filters from the popular brands of photographic filters tend to be quite expensive, and this one in particular is less expensive and produces results equal to and even better than those of the most reputable filter brands. It is made of glass, which is an advantage over resin filters because it does not scratch as easily. I really liked the filter cover, which is made of leather with interior protection. In short, I liked this filter very much and I am sure that I will use it very often in my landscape photography.

Anyone who enjoys photography knows what to use an ND filter for. Since my focus is on landscape photography, I can't avoid working with such filters. I ordered this from K&F for my full frame camera.

I just got tired of stuffing my backpack with ND filters of different strengths. That's where the Nano-X Pro came in. In order to use it on several lenses I ordered it in the size 77 mm. I then work with step rings to be able to use it on smaller lenses.

To say it straight away: the optical quality and the quality of the pictures flashed me! The processing is excellent and very successful. The lens thread is cut very cleanly.
The filter can be adjusted from ND 2 to ND 32. The larger levels (apertures) are marked on the ring and are easy to read. It can also only be rotated in this range from 1-5. It doesn't go below or above. So you always know what you have set at the stop.

The 77mm. Ring brings 93 gr. on my kitchen scale. Everything is solid and feels very good. The adjustment goes well with slight resistance. It should be so.

The optical quality is absolutely flawless and the filter delivers top quality even in difficult lighting conditions. I could not determine any chromatic aberrations or color gradients into green, magenta or anywhere else during pixel peeping. The quality of the filter is unsurpassed, even with backlit foliage or fir trees and reflections from dew. Finally an ND filter that does justice to my limited lenses and full frame sensor. The frame thickness with thread is only 9 mm. Without thread 0.63 mm. So you can also use the filter on wide-angle lenses without edge shadowing.

Thanks to the two screwed brass handles and the ribbing of the ring, the filter can be adjusted very sensitively.

Conclusion:
K&F Concept has delivered a top filter here. What's the point if you put thousands in lenses and then bad filters make the job difficult or give lousy results? Clear 5 stars+ from me. I hope this is helpful in your purchase decision. The price is also relative because you save at least 4 ND filters.

Since I discovered photography as a new hobby, I was looking for different filters. With this ND filter, you can turn day into night and thus make long exposures during the day and at dusk. By manually adjusting the filter, this can adjust to the appropriate environments and lighting conditions. I can absolutely recommend this filter.
