A completely different use for this lens. We were camping near a waterhole in Botswana when we heard a lot of elephant around us. There was moonlight but too dark to see where they were exactly. Took photos in all directions to be able to see where they were. We were completely surrounded! Not great photos by any means, the focus was way off and handheld (F1.4, 0.6sec, iso 12800) but at least we could see in the dark!
