shooting wide and real close with my mama's tiny Fuji thing. Wish i could use something like that piece more often. But i shoot at night far too much. This older model of Fuji maxes out at 6400. I shoot a lotta 10,000-12,800-51,200 and even some 60,000iso sometimes. These file sizes sorta annoy me sometimes, have to keep reminding myself the the sensor is 4 times smaller than my big, fat, and heavy DSLRs.
