I ordered this “K&F Concept 62mm ND1000000,” Filter after a substantial amount of research, specifically for photographing the upcoming Solar Eclipse on April 8, 2024. As a ND100000 it provides for a 16.6-stop light reduction and is “mostly used for solar photography and long exposures, such as solar eclipses.”

The filter itself is packed in a branded circular plastic case. K&F uses the same size case for many different sized filters relying on internal raised ridges to prevent the filter from slipping inside the closed container. My personal feeling is that this makes easy differentiation between sizes and storage more difficult than it should be though I appreciate the hardness of the plastic used for its protective quality. Delivered with the filter were two Microfiber Cleaning Cloths,

The filter is made from lightweight aluminum with matte black coating. The screw threads are well cut and the filter screws on and off easily. Comparing the filter to other K&F Concept filters I own I am confident that when the eclipse occurs it will perform as well as the others I have and I am looking forward to using it on April 8 to phtograph the eclipse. I consider this filter to be a strong 4 star filter and easily and securely recommend it to others for its photographic quality.

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.
