OK, this came up in an Off Topic thread I started. In the ISO menu setting where you select ISO Auto On or Off, there is a minimum shutter speed setting also. If it is set to 1/500s for example, should the shutter speed ever drop below that setting in any modes other than Manual or of course Shutter priority where it can be set to anything? The setting does not seem to have any effect on my D5300. The shutter speed will go to 1 or 2 s if that is what is required to get the proper exposure. Do I have a camera problem or am I missing something?
Thanks
The Minimum Shutter Speed in the Auto ISO menu is NOT a minimum shutter speed. It is only the minimum speed in Auto ISO before Auto ISO increases.
It is the shutter speed threshold for Auto ISO increase (when the shutter speed drops that low, shutter stops there, and then Auto ISO starts advancing.)
Therefore it is obviously the shutter speed that most Auto ISO pictures will generally always use, so it is very important, choose it wisely.
If you set it slow or fast, then it likely is always that slow or fast (anytime ISO is between Minimum and Maximum ISO, shutter will be that setting).
But when Auto ISO maxes out at Maximum ISO, then shutter speed automation has to go lower if you expect a proper exposure.
Auto mode is a little different, in that it is always Auto ISO, cannot turn it off. No user settings for anything, including not for Minimum or Maximum ISO, or for Minimum shutter speed. No bets on what happens then.

For a few of the recent less expensive camera models, Nikon ships a skimpy manual, but has a full Reference Manual online, which is much more complete.
(at
Nikon Product Manuals available for download | Nikon Knowledgebase )
For the D5300, it is at
Reference Manual - D5300 | Nikon Knowledgebase
Page 181 says: In modes P and A, sensitivity will only be adjusted if underexposure would result at the shutter speed selected for Minimum shutter speed.
That is Nikon speak for what I said
Says in S or M mode, the shutter speed selected by user serves the same function.
