Geez, I took a series of pictures of the last big one with a 35 mm Pentax. No filter. It works just fine.
I admit I’m ignorant on the subject, but just passing on info from my husband with PhD in Optics (lenses, mirrors, etc., for defense contractor). Also, I read a bunch online because my sister was asking.
I think it’ll be interesting — maybe fun — to get feedback on the experiences of all of us once the eclipse is over.
