My experience is only at ISO 1600 with the Canon 350D. In typical nighttime situations, ISO 1600 with the 50mm f1.8 which is a very fast lens, gives about 1/2 second to 2 seconds exposure time. ISO 12800 is 3 stops away. So that would give 1/16 second at best. 1/16 second exposure time is still not short enough to avoid blurring effects. I must add to my “curtained daytime room” analogy.

To get ISO 10000 or almost two stops above ISO 3200, on a traditional tiny 1/1.8" sensor means lots of sensor gain. Which means lots of sensor noise. As in REALLY lots of sensor noise. And "pitch black" is not quite, too. In a curtained daytime room, with a 50mm lens at f1.8, ISO 1600 requires 1/25 second. So ISO 12800 would require 1/150 second. That's a CURTAINED DAYTIME ROOM. To wit, ISO 10000 will give really horrific image quality (the DSLR's which have huge sensors with high quantum efficiency, only go to ISO 1600 or 3200, and their sensors are about TEN times the areal size of this camera's). And it won't work in total darkness. Sony's Super Nightshot is a better approach: illuminate the scene with infrared diodes, which camera sensors are very sensitive to, but infrared light is invisible to humans. But you won't be invisible to that sniper with an infrared scope. Zing! That’s not too nifty.
