I knew that reports were good about the most recent 16Mpx sensor, which is why my auto-ISO maxes out at 4000. That's the ISO of the top image here; exposure calculates to EV3. I really did not expect the ISO 20000 image (bottom) to look this good though! Colors are very good, detail is available, contrast / dynamic range isn't degraded like I expected. Plenty of detail in the blue wire. BTW These are both jpegs taken at full resolution with NR set to low - well I think that's the setting.. man those menus confuse me! The Sigma 30mm at f/3.5 did a nice job. These are not 100% but they are decently cropped from the original. I am not the peeping type so this will have to do. Makes me wonder how the raw image could turn out at iso 20k!
