>>3570599It's not very useful. I very rarely shoot at iso6400, though. I've my cam locked 1600, and I'll extend it to 3200 when I really need higher shutter speeds.
Generally, in good light you can shoot iso6400 on m43 cams. In low light, you're probably forced into converting them into b&w to get something usable out of it. Bottom bug was in natural light and in shadow, but still daylight. I'll look if I have anything that's really in low light. I either use flash or shoot at base iso and at very low shutter speeds.
