72mm True Color Variable ND2-32 (1-5 Stops) and CPL Circular Polarizing Lens Filter 2 in 1 for Camera Lens Neutral Density Polarizer Filter Nano-X Series

There was a defect, but it was fixed without any problems. The staff were very friendly and helpful in helping me with my problem

The presentation of this filter is very good. I think it is an essential accessory for sunny days. It has a regulation with values from 1-5. It is for a 67 lens, in my case I am going to put it on my 85 F1.8 Sony and on my 18-70 F4. It is easy to place, since it is only screwed on.

Hello everyone. A filter like you rarely find. A neat quality with a very well-made case worthy of a jeweler. The adjustment is done smoothly, the filter offers a wide range of settings. For my part it is mounted on a 28-80L f2.8. Extremely satisfied with the result. Friendship, Laurent

Very high-quality filter: combination of polarizing filter and gray filter. Who needs it? I think everyone who wants to take good photos. The polarizing filter reliably reduces reflections and makes colors (e.g. slightly cloudy skies) shine much more intensely. The pictures already show the simplest use. The gray filter enables longer exposures even during the day. Of course, you need a tripod for that. By turning in one direction you first set the polarizing filter, then you can make the gray filter increasingly darker. The workmanship is very high quality, which justifies the price. Packed in a high-quality cardboard box and a leatherette box. This is a great gift for photo freaks. Check out Siegfried Eichhorn's video on YouTube about ND filters. Then you'll press "order" at the latest! With the right adapter rings I can now use the filter on all my lenses. I am impressed by the quality.

have used filters for the lens of the Reflex in the past for two reasons: high altitude photos in the summer with a strong sun and photos of water flowing in streams to create the "flowing" effect. Both the lens and the filters were cheap, but now I have switched to a 100mm macro lens with a decidedly high cost, therefore the filters also need to be of quality to support the lens itself. This filter from K&F struck me because it integrates in a single product what I previously obtained with two separate filters, and since, as simple as it is, changing filters when the subject changes is always inconvenient. The product arrives super protected in its leather packaging, a sign of the importance the manufacturer places on preventing it from getting damaged once stored with other photographic equipment. The construction quality is immediately noticeable in comparison with previous filters: we are on another planet! Furthermore, the filter has two handles to adjust the two internal rings which are very comfortable because it avoids adjusting the wrong one if you had to do it using the edge. Let's say right away that for the test, due to rainy weather, I could not extend it as I should, due to very diluted natural light. However, I chose to photograph the live sphagnum, because it has an intense green color that often escapes the normal lens, looking for the patch of sky where the brightness was higher. As you can see from the photo, on the left there is the sphagnum without a filter with the 1:1 macro lens and on the right the same shot with the filter inserted (obviously used at maximum brightness in this case). The colors are now clearly better. 5 star rating: barring any future updates when there will be weather that will allow a better outdoor test, I am currently fully satisfied with the filter, whose price is adequate for a lens that costs 10 times more.

The K&F Concept Nano-X True Color ND Filter 49mm Polarizing Filter&ND2-ND32 arrived quickly. It is very neatly and safely packaged. The filter is of very good quality. Very high-quality materials. Superb workmanship. The settings can be continuously adjusted using the small red handle on the edge. With its 49mm, it fits exactly on my kit lens. If you have lenses with a larger diameter, you should choose a correspondingly larger filter. I still have to practice using the filter correctly. But I am already very impressed.

First let's recognize that this filter is very well presented in a beautiful imitation leather case itself packed in very neat cardboard.

The filter is perfect, the unique observation is that the little orange clip, I thought it was to move the nd and other the polatizer. Maybe in the future with one each color.

As a filter, for both polarizing and variable ND, this is a solid 5 stars! I'll explain 4 stars to get this out of the way—the filter is large in diameter, and those orange grips stick out even farther. This will not allow any of my lenses that use this size filter use their lens shades at the same time. Also, (and this is probably necessary, to avoid vignetting), there are no receptical threads in the front—so you can't use your lens cap when the filter is attached. I have a feeling that this larger diameter is an issue with most variable ND filters though. Now that those issues are out of the way, I can speak to the positive attributes. I have a number of very good polarizer and Neutral Density filters (none combined) from top manufacturers. I've avoided variable ND filters in the past—pretty much every review I've read mentions an "X" that appears (as a darkening) once the filters are above 3 or 4 stops. But, since I've used several of the higher grade K&F filters (UV and ND) and have seen how good they are, I thought this one was worth a try. First the polarizer. I've attached two birdbath photos—one without and one with the filter at maximum effectiveness (with the ND set at 1). (Note that without the polarizer, I was focusing on the reflection on the water surface, so the birdbath and surroundings are out of focus. This also affected the overall exposure.) To my eye, this is working very well, without creating undue color casts, and the exposure is even across the image. Next, the ND The first shot is no ND filter at all, and the second shot is the maximum 5 stops of this filter. There is a very slight color shift between the two; it's possible that if I didn't have color temp. set to auto on my camera, the difference might be more apparent—as it is, the correction needed would be easy in post. The main issue to me, is that the color shift is even across the image. And, the only ND filters that I have (and remember they are fixed ND, not variable) that have less color shift than this cost more than this filter. (And, they are just a single ND and there is no polarizer in them, either.) The filter comes in a very nice case; I'm undecided if I like this better than the typical top and bottom lock together "caps" or self hinged snap box that all my other filters come in. It doesn't take up more room, and it's fun to pull the orange webbing and watch the filter lift out of the case.

This "K&F Concept 77mm True Color Variable Fader" is quite a well designed and constructed filter. It is a "twofer" in so far as it combines both a Neutral Density (ND) and a Circular Polarizing (CPL) filters into one easy to use screw-on device. The build quality is impressive, as have been the majority of K&F filters I've ordered over the last two year. Further, the filter comes packed in a leather case with a pull-out tab to slide the filter out for use. If forced to find a fault it would only be that I wished the filter went further in its light reducing abillities. Having said that about its ND2 to 32 range, I must also heap praise on the filter for the orange finger putters which allow you to move the filter in gradual amounts instead of only being able to set the filter on full stops. Thus the combination of the CPL function (which cuts out reflections from water or stray light from unwanted directions) together with the ND function (which diminishes the amount of light entering onto the camera's sensor thereby allowing longer exposures) provides the ability to get smooth shots of such things as moving water without suffereing any glare from reflections. The K&F brand of filters, as a whole and specifically this "K&F Concept 77mm True Color Variable Fader," are well made photographic filters that are true to size and perform their intended effect well. Comparing this filter to similar filters from other makers leaves me with the definite thought that for the cost, fit and effect the K&F filters perform quite well. This filter, specifically, is an impressive filter at a reasonable price and I think it is, if not a spectacular build, definitively better than the average. As such I think that the "K&F Concept 77mm True Color Variable Fader" is unquestionably a strong 4 star product which deserves a place at or near the top of anyone's comparison shopping list.
