Just for the heck of it I decided to try ISO 12,800 with my Olympus EM10 ii, figuring I'd lose a lot of detail and the noise would be intolerable. Much to my surprise, it came out quite well. I'd never shot at such a high ISO with this camera. I always loved it, but now I love it more! (Next shot, was taken in fading daylight; this was shot with ceiling floodlights.
