My macro lens has exposed a few imperfections in the glass lens(?) on my brand new blue Mini-Maglite. I might be a little upset if one of my camera lenses looked like that but I don’t think it matters too much on a cheap flashlight. I am always surprised at what my macro lens reveals that the naked eye seems to have trouble discerning.
Focal Length 105mm; ISO 100; f/36; 2.5sec.
