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.

My Rating Scale:

1 star. This is the absolute lowest I can go and is a definite recommendation against being purchased.
2 stars. Less than average - having issues that I try to delineate in my review. I personally would not pay for this item.
3 stars. Average - neither great nor terrible. It will do the job it is supposed to do but without any obvious good or bad issues.I might or might not buy this item depending on the severity of my need or want.
4 stars. While the product is better than average it is not an excellent product. I would probably buy this product.
5 stars. Enough above average that it exceeds my expectations of how the product would and should perform. A product getting this rating is highly recommended.

Was the best purchase of mine monetarily and this micro is awesome easy to use fast delivery!

The filters themselves are great. It doesn't affect your colors (I already had other filters with a green tint). The set is well packaged, but the case doesn't really seem to be of high quality. The reason I'm deducting a star is the fiddly assembly. So I switched to magnetic filters. They were cheaper and much more practical. Therefore a star deduction for the handling. If you don't mind the fiddly assembly, you can buy it here.

Fits, does not wobble and has no air ;-). Does what it should and does it excellently.

These are great low light filters. Due to the 1" sensor on the Air 2s, darker filters are required for bright/very bright days.
I already owned a filter set of the same brand for Mini 2, I bought it for Air 2s. What can one say about quality at the right price? K&F Concept is on the safe side.

These ND filters are great! First, they feel well made and fit the Air 2S drone perfectly. I tend to use them a lot more when it's very sunny or when I'm trying to get a specific shot without having to edit it afterwards. I don't use them all the time, but they're excellent when you need a specific shot or effect. If you ask me, these are must-haves for your drone gear bag and this kit gives you more than you're likely to need.

Excellent filters for the DJI Mavic 3 Classic. I had already bought and repurchased them for the Air 2S because they are necessary to take some good videos and photos. I recommend this brand for quality and price. In addition, with these two filters you cover the entire range of the full day package. The quality is there.

Human sick easy when not good Air. This is perfect indoor monitor for air which you can control ion your house and reset or clean it. it also smart so connect your phone and humidifier so you can control air.
