55mm Solar Filter ND1000000,20-Stop Solid Neutral Density Filter Celestial Event Photography Filter with 28 Multi-Layer Coatings for DSLR Camera Nano-Xcel Series

I purchased this “K&F Concept 77mm ND 100000 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.

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.

Great quality!

I bought for the eclipse. And having done lots of research, and the reading reviews… I think people will try to take pics of the total eclipse with filter on. This filter is meant for sun. So when the moon covers completely, you take the filter off. Otherwise it will be too dark. You need this filter for the phase up to and after the totality - for all partial portions.

Can't wait to see if this will allow me to take great eclipse pictures on my Nikon camera!

I purchased this for my Pentax K-50 camera with a 50-200mm lens to use when the solar eclipse comes on April 8th, 2024.
I finally had a clear day with full sun today, 3/8/2024 (one month away from April 8th!!) so I put this filter on my lens and took some pictures of the sun. They came out great!! This filter will work for the total solar eclipse and I'm excited.
Buy one that fits your lens and you won't be disappointed!!!

I have a number of solar filters, but these ND filters are awesome! The solar filter(s) that I have often leave a bit of a blue tint to the image, resulting in the photos requiring color correction after the fact. This ND filter doesn't affect the coloring of the sun; it's quite nice because these have the effect of just a pair of incredibly thick sunglasses. I can't wait to update this review with pictures of the solar eclipse!

Bought for the upcoming eclipse and did a test shot on a Sony A7r3 with Tamron 150-600mm with 82mm filter. I attached a test shot and I'm happy with the results.

The K&F ND100000 comes in a large case (see photo). This is a quibble, but I prefer a smaller box for a 58mm filter; it takes too much space. As with all K&F products, this filter is well constructed. It screws on easily on my lens and has large knurles for easy grip.

I compared two shots using my prime 24mm lens. One is a shot without the filter f8 @ 1/1000. The other is with the K&F ND100000 stop filter f8 @ 1 minute 15 seconds. As can be seen the colors are shifted a bit, so this is not a true neutral density. But they can be corrected in post. At this price point, the colors are close enough for most photography.

I've got a few other filters from K&F and this ND100000 is no different!

While I haven't had the chance to try it with an actual eclipse yet, I can confirm that it works well with just taking a photo of the sun, or other very bright light source. Remember, never expose your camera sensor or your naked eyes directly to the sun or you or it will go blind!

Build quality is on par with other K&F products. Very happy with it!

I don't know if I'll ever get any real value from these solar shots, but at least I got to experience it because of this ND10000 filter! I'll have to keep experimenting (and probably get a longer lens) to get better shots in the future, but it's pretty cool to see the cool spots in the sun's surface on my own photo.
