Appreciate informed sources on safety using Kase ND 100000 filter on lens during solar eclipse
Mar 28, 2024 07:58:25 #
BH sites says the filter is safe for the camera/lens but not for viewing. Other sources say to never use an ND filter for a solar eclipse as it does not filter IR or UV and will damage lens and camera. Other sources say that an ND filter greater than 16 stops is safe for protecting lens/camera. With so much conflict in opinions is there a source of accurate information? Perhaps one should go with just a solar film filter like 1000 Oaks. Of course ND filters have the advantage of being threaded vs film filters that need to be attached by another means. Not sure the convenience of the ND filter is worth the risk without hearing from an authoritative source who can clarify the science. Appreciate any input anyone can provide.

according to nikon,,solar filters are the only safe route. i've seen posts where people say sunglasses over lens is safe,but that is definitely not true. don't risk eyesight or camera issues. i just look at others pictures to enjoy!

Why take any chances of possible harm to your eyes or your camera? You can buy a solar filter for $20 to $30, and not have to worry about it. I picked one up for the 2017 eclipse and it worked great, and still does.

B&H has information on the Kase Filters. Please read it and make your choice.

Your ND filter is acceptable for full sunlight for your camera but not for your eyes. The filter you have is ND to 16 stops which is different from the 1 to 3 stop ND filters one uses for making silky waterfalls and such. Your filter will not stop UV rays. If you have a DSLR or use the filter for viewing with your eye, you will sunburn your eye (sunburn = blindness or serious eye damage; forget further photography with that eye). If you have a mirrorless camera, no problem; you are viewing a screen and not actual sunlight. But you still cannot use that filter with just your eye (filter is still passing UV rays to your eye and sunburning your eye; damage is felt within a day). Thousand Oaks sells sunshades that will protect your eye while viewing the sun directly. You can watch the sun all day with those sunshades and no danger. The only other way of protecting your eyes from direct sun viewing is welders glass of ND16 to ND19. Welders glass cuts both the light level and the UV rays that are generated by welding.

See response by wdross. That provides correct answers to your question.
To those comments I will add this: I have the Kase magnetic 16.5-stop ND about which you inquired. I have tested it shooting the sun on a MIRRORLESS camera by both looking through the viewfinder and by focusing on the rear screen. No damage to camera or eyes. (Reiterating others' warnings, if you use this filter on a DSLR, DO NOT look through the viewfinder.)
I will not be using this filter for the eclipse, however, because it renders the sun as pure white, not the yellow/orange we perceive it to be. Some like that "look;" I do not. B&H sells several solar filters that render the sun yellow/orange. I will be using one that attaches to the outside of the lens with three thumb screws. Instead of attaching it directly to the lens, however, I will attach it to the lens hood, making removal and reattachment of the filter a quicker process during the critical diamond ring-totality-diamond ring phases.

A ND 100000 filter IS a solar filter...just that the terminology gets mixed together.
B&H knows what they are talking about....here is a Freewell site...reputable.

I use a K&F 100000ND...perfectly fine...both for my camera and my eyes (which never look through the lens anyway on a mirrorless).
It's perfectly fine...just buy a good one.

Use only solar filters for eyes. Camera, binos. Only during totality can you go without
