Originally posted by Just1MoreDave With slower kit lenses, the camera sees 3200 as a good way to maintain other settings in reasonable values. You might want to just allow the camera to do noise reduction on high-ISO shots (if you are shooting JPEGs) or use software noise reduction on RAW files.
I've noticed that with lenses with lower resolution, higher ISO is a bit more usable because noise reduction works better on them. At leas, Topaz works better at higher settings. I think because Topax is trying to preserve detail, with a higher resolution, it confuses detail and noise. When the lens doesn't bring forth as much detail, what is noise is clearer and there's less detail loss at high settings (in part because there was less detail to start).
Originally posted by jayman_1975 I find that too in lower light conditions. It seems it will always up the ISO instead of lower the shutter speed when using Green mode. The camera must figure you can edit out noise but you can't do anything with motion blur.
I also suspect that some of programming is from back before shake reduction, so the camera avoids those low shutter speeds it can do now.
