It fits well on lens, darkened enough... easy to take on and off and the package fits well in camera bag

works well with 250mm lens

I used this filter on a Nikon D5600 for solar eclipse. I was able to capture some nice shots of the event. I would definitely recommend this for anyone in the path of an eclipse.

I got both the ND100000 (16.6 stop) and ND1000000 (20 stop) for the Apr 8 2024 eclipse. They both worked well. I used the 20 stop during full sun at ISO100 f8 exposed between 1/4 to 1 second. The 16.6 stop max'd out at 1/1000 sec during full sun, but worked great shooting thru thin clouds with about a 1 second exposure. These are a good inexpensive choice for solar photography. Sun spot will show but you need an hydrogen alpha (Ha) filter for solar flares. CAUTION As the amount of UV blocking is not known, don't use the optical viewfinder, instead use the electronic live-view screen to protect your eyes!

Yep, it's a solar filter.

I took this picture of the solar eclipse on April 8th, 2024 with this filter! It works as expected!

The sensor is totally fine!

PS. Looks like I overexposed the eclipse. I attach another photo of the sun, the exposure is shorter and you can even see the spots on the Sun!

I bought this for the eclipse and was quite happy with the results. I am a beginner photographer.

Whose product did great. Enjoy the solar eclipse with it. I would recommend buying this

I knew I was probably only going to use it once for the solar eclipse. It did the job and didn't degrade much that I could tell. I didn't have my settings perfect in camera, but that's mainly the pressure of the moment. I only had three and a half minutes with zero experience with a total solar eclipse. I think it went well.

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.
