I don't think even if the camera was set to auto, it would use those settings!
You really need to bring down that iso, open the aperture to get more light in, set Exposure Compensation to 0, and slow down the shutter speed
I fully agree, but if Auto ISO (but Not camera Auto mode), and if the Auto ISO menu said Minimum Shutter Speed was 1/2000 second, then it might do exactly that
It is a possible choice, but surely not a wise or thinkable choice.
I don't see how it was said 1/2000 at ISO 6400, but these are pencils in a cup, and there is no motion to need 1/2000. Thinking Auto would not have done that, if it were camera manual mode M (?), the +5 compensation had no effect.
So this picture needed to put the camera on a tripod to steady it, and use ISO 100 at f/16 at perhaps 1/8 or 1 second shutter speed. Whatever shutter speed it needed. Camera A mode.
