K&F Concept 95mm ND100000 Fixed Neutral Density Filter provides 16.6 stop light reduction. That's the suitable level of light reduction for a super telephoto to photograph the blinding sun. I used live view on the tilting camera LED screen to view the sun versus peering into the viewfinder. As the light level was safe, I viewed through the viewfinder with some dark polarized sun glasses on to further protect my eyes.

Initially I set my Nikon D850 camera to aperature priority which worked fine and now I'm shooting in manual mode for full control. My Nikor 200-500mm lens and 1.4 teleconverter gets up to 700mm at f6.3 max aperature. With full zoom, I get a good exposure @ ISO 64, 1/250second & f/11 aperature w/ -1 stop under exposure to avoid exposure wash out.

Light balance is on auto and I get a very white/grayscale image. Changing white balance to daylight renders a yellowish tint. But with the sun, daylight is pretty white and likely in post processing I can change the white balance. I'm hopeful that for the upcoming solar eclipse, I don't have to make too many other major adjustments so I can take a series of interval shots to capture the eclipse cycle.

This lens filter is a uni-tasker. Other than using this specialty filter for looking at the sun, there may not be other common uses for this at 16 stop ND filter. So for the price, this is one of the great value for for safe sun photography.

This is for the K & F 82mm ND100000 filter. At the end of the description it says that this will need a 95 mm size. This is confusing. I am not sure what is happening with the description . This is an 82 mm filter and fits an 82 mm lens. Taken near sunset with Nikon P900 and 67-82mm adapter rings. Works great for me.

TL;DR - Unimpacted Image Quality | Perfect for Aiming at the Sun

DISCLAIMER - This review sample was provided to me free of charge. The opinions expressed are solely my own with no input from either manufacturer or Amazon.

I have purchased many K&F products with mixed results, but one thing that has been very consistent has been the quality of their filters. This filter is no different.

In my testing I found that there was no perceivable loss to image quality, and it's ND properties were consistent with my more expensive B+W ND filters. The amount of light this thing can block is crazy and is perfect for doing very long exposure.

I do wish the screw threads were slightly better and that the outer ring material was more robust, but considering the price something had to give.

Bang for buck though it's hard to beat K&F when it comes to filters. Just don't buy their batteries.

5/5 Solar Flares

It fits my 200 800mm very well 95mm. It feels like a decent quality filter. 16 step ND is good enough. Can't wait using it for Solar Eclipse next week!

This K&F filter threaded on perfectly and reduced the sun's brightness to camera safe levels.
The filter comes in a convenient carrying case which is useful since it will be rarely used and will need storage.
I haven't the experience to take decent photos yet, or to determine how many f-stops of reduction this filter offers, but if I can figure it out I will update.
It's well priced for a quality filter, and when you need it you need it!

The K&F Concept 82mm ND100000 Optical Glass Filter Neutral Density 16.5 Stop ND comes in a typical plastic storage/protection case along with 3 microfibre cleaning cloths in sealed envelopes to keep then clean until needed. I see no reason why the microfibre cloths can't be re-used; they just ensure they are kept clean until you need them.

The ND100000 is dark enough to photograph the sun providing 16.5 stops of light reduction. Most ND filters will induce a colour shift in the photos. I took two photos of a white card: one at 1/160 s and one with the ND filter at 6 min 50 sec. Colour shift with the K&F Concept 82mm ND100000 was minimal. Using the eyedropper to correct white balance, there was a net difference of 150 Kelvin, which is negligible. I've posted comparison images with no processing and aonther with the same white balance applied and a +0.50 exposure increase on the ND photo to balance exposure. You can see a very subtle shift in colour, but, as I said, ALL ND filters will have some colour shift, even the US$100 - $200 ones.

The K&F ND100000 performs very well and is a great value.

The filter works well and does not cause lens reflection on photos. The filter screwed on with ease and has a metal bezel that is easy to grab onto as well. It is very easy to read the filter information printed on the side. The filter came in a protective case as well as included microfibre cleaning cloth. I am sad. I did not have this in time for the eclipse, but I will be ready next time. until then, I will continue to practice on some of these cloud photos and other very bright situations.

I have a few K&F items in my accessories list at this point (including drone ND filters), and this one is just as good as the others. It comes in a nice hard shell case that you can throw in your camera bag. I do have a minor gripe about it that it doesn't have the foam inside the case that my other K&F filters so, so it can bounce around a bit inside the case. That aside, the case protects it well.

As far as fit goes, I got this in 58mm, and it fits on my lens perfectly. I tested it for density against a couple other ND filters that I have for other lenses, and it seems to be a close match, so it's safe.

Works great. I'm becoming a fan of K&F stuff.

I am using this filter with Tamron 35-150 lens and the 82mm fits well the lens. The filter feels well made and it does the job as advertised. In addition to the very unique application of taking pictures of the sun I think there is the chance to take some creative shots. The cleaning cloths in individual packages are a great asset and they are good material perfect for cleaning the lens.

Works great!
