p.1 #1 · p.1 #1 · Eclipse- need a filter for a wide angle lens?


Is it necessary to get a special filter if one is using a wide angle to normal perspective lens? I have no interest in filling the frame with the sun but want more of a landscape type of shot. Thanks.

You need a filter.

You won't be focusing on the sun itself with wideangle lens, so you don't need the filter. During partial eclipse the sun is not stronger than daily sun.

When you need the filter is if you are focusing on the sun... damage to sensor, eyes if looking through the lens. You also need a filter because the sun will be washed out otherwise and white. The eclipse will happen during the middle of the day.

half sun, sunrise..... already exposure of 1/5000s f/16 - ISO-100

Thanks to both of you. I went ahead and ordered a solar filter for my Lee filter system this morning. There is so much conflicting information about this topic. I sure hope it is a clear day!

Solar filter is about 14 stops reduction of light. That will make the sun look properly exposed. The sky around it and anything else (other than very near clouds) will look black.

I read somewhere that the solar filter is not just a ND filter but eliminates other types of harmful rays too??

Hello & similar question here. I already have a 10-stop ND filter... how will this do?

It's this: https://www.bhphotovideo.com/c/product/752928-REG/B_W_1066186_77mm_110_Solid_Neutral.html

I'll be shooting Nikon D5 probably with 70-200mm f/2.8-22 (longest I have...that'll be short & boring unless I blend in landscape which won't be easy given with the Wyoming mid-day high sun...). I can zone focus, live view focus, optical focus with sunglasses or eclipse glasses, etc.. A quickie shot today, 10-stop, 200mm, f/11, 1/1000 at ISO100 is still 1.5 stops from saturation.


Thanks much!

You darken the sun, you darken the landscape. By 14 stops. All will be black if sun looks yellow and good. With a solar filter.

solar filter besides darkening, also removes ultraviolet and infrared radiation

Or you can have a landscape photo with 70-200mm or shorter, with ND, don't look through viewfinder, use live view shortly, then turn off autofocus.

sun 10 minutes before sunset. lot less strong than midday sun which eclipse will be.

my suns are white. if you make them yellow with 10stop or 14stop of filtering, all else will be black. but if it's a landscape up to like 70-200mm where sun is small, the yellow color is not what you want, you just want to show the eclipse effect as part of a scene.

I don't know for sure but I thought about getting one of those too. I was concerned the filter may not be perfectly flat and might waffle? Best wishes.

Yesterday I had the option to get a Lee 100mmx100m solar filter from B&H, but was hesitant to spend $160 for just a few casual shots since I already have the 10-stop. Now the option is gone and the time short to get one by Saturday before road tripping. Of course don't need to damage a $6K camera body.

Can't we zone focus or focus on far target since a relatively small f-stop will get used anyway?

Remember. If you have shot landscapes with Sun in them, it's no different during the eclipse. And if you are on the path of totality, during the total eclipse, you don't need any filters but a tripod.

Years ago, a photog buddy burnt the sensor in is 5D by bracketing a few shots in one place without any filter. Being an impoverished working photographer, he just lived with this new burden and had to repair the spot in all his following work.

I don't know what photo opportunity I'll find once I get a my friend's farm in Wyoming (I hardly touch a camera these days), but the usual boring corona shot will involve repetitive frames like my buddy's experience. It's one of those things... the chances of doing damage is probably small, but the cost of doing so is large. Given the throngs headed to see this eclipse, the money shot might be a people picture.
