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.

Disclosure:

As noted by Amazon, I am part of the Vine Program which means that I acquire products at no cost in return for a truthful rating. However, although Vine Members pay nothing up front to get these free products they are considered by the Internal Revenue Service as taxable income at the full retail price at the time we get them and we, therefore, must pay taxes on these items.

On a more personal note I often read reviews for products I am considering buying and rely on those reviews that are detailed and come off as honest and full reviews on the product. I therefore try my best to give a true and honest review based on my own experiences with the product.

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.

Further middle ratings: The above explanation is the base of the recommendations I give in a review. Some ratings are further rated as soft (1/2 star below), solid (the star rating given) or strong (1/2 star above)

I did not buy this filter, I bought a size 77mm and for the price I am happy with it.

I only got these for the lens caps... I don't use the Keepers and already have an awkwardly sized bag full of new microfiber cloths as they seem to come with almost everything these days.

BUT since I have many lenses with smaller filter ring diameters that I size down to 77mm by using step-up rings so they share a common filter size, I often run into shooting with an unprotected 77mm filter on the end of mine rigs around.

This is exactly the quality you would want from them. Nothing fancy but perfectly functional and easy to use/operate with one hand without looking. The set of three is useful because I need at least that many and will definitely lose them over time in the black holes that are my pockets.

No complaints!
