The Casio Exilim EX-V7 has user-selectable ISO up to 800 in manual exposure mode. However, the High Sensitivity "Best Shot" (scene mode) mode will go up to ISP 1600 and I am very impressed with the results. Although it's always best to try to use a lower sensitivity setting, I have no regrets about using the High Sensitivity mode when the light is low and I don't want to use the flash.
