[QUOTE="WayneF, post: 510100, member: 12496"] Yes, sort of. The Auto ISO menu on Nikon DSLR have a "Minimum Shutter Speed" setting. This is not a true absolute Minimum, but is instead a threshold for Auto ISO to kick in. It works this way (assuming camera mode A or P or Auto, but not S or M of course): In the Auto ISO setting, you set say ISO 100 minimum, ISO 3200 maximum, and say 1/100 second minimum shutter speed. In bright scenes, it might use ISO 100 and shutter speed maybe 1/500 second, as normal. As the light becomes more dim, shutter speed drops slower, as normal. When shutter speed hits the 1/100 second limit (if set at minimum shutter speed), then shutter speed hangs there, does not decrease, but then ISO starts increasing. Anytime Auto ISO is acting (above minimum, below maximum), the shutter speed will be the 1/100 second (minimum). All of the Auto ISO range uses that shutter speed you set (so it is important). You may want it a little faster than 1/30 second. All of your high ISO pictures will use that value. When the light gets more dim, and when ISO 3200 is not enough, then since ISO cannot increase above your maximum, then shutter speed has to drop even lower, as normal. So, it is NOT an absolute Minimum shutter speed. The goal is still to provide a proper exposure, whatever it takes. Using a flash can alter this action somewhat, the minimum shutter speed with flash comes into play (it wins conflicts), and ISO with flash has a high limit in some models... camera models vary, if using flash. There are ifs and buts... if the flash is seen and recognized as a Manual flash, then Auto ISO is automatically disabled (a manual flash cannot respond to Auto ISO). My own notion is that it's always a good idea to turn Auto ISO off with any flash. The idea of Auto ISO is actually to take effect "when all else fails"... some physical limit is reached. For example, in camera S mode, the aperture varies. When the aperture hits wide open and can go no more, then Auto ISO kicks in. This means Auto ISO is always using a wide open lens (in camera S mode). In camera A mode, the shutter speed varies. But that means Auto ISO does not kick in until shutter speed hits its physical limit at 30 seconds. That is too slow, not realistic, so instead, they provided this artificial limit (called minimum shutter speed), to be the threshold where Auto ISO kicks in. You can set it wherever you like. All of the Auto ISO range will use that shutter speed you set, but it can go slower if required. [/QUOTE]
