because i'm in aperture priority and i have no control over the shutterspeed.
and i want enough shutterspeed to freeze the subject or help with my shaky hands. of course if there's plenty of light the ISO will stay at the lowest.
that's on natural light. different case if i use strobe but still i like less than 50% flash contribution on my strobe(except if the background is too bright) to avoid having a flashy look so i might still need the ISO if needed.
review Dave Morrow's video, he wanted his shutterspeed to be at 1/15sec so he raised the ISO
and for the most part on my normal portrait session around the golden hour, maybe the max ISO will be ISO400 to get a decent shutterspeed, which is nothing on this camera.
So there's lots of ways to skin a cat, but I think auto ISO Sony's minimum shutter speed setting, and the ISO performance of the body simplified things a lot for me.
Basically when shooting portraits or events, shutter speed usually only matters to the extent that my photos are not blurry because of motion or shaky hands. This is a non-issue like you said for outdoor portraits, as the ambient light is so high that your shutter speeds are really fast, but when the ambient light drops and the metering system is doing its thing, I want established lower bound thresholds to make sure that the camera isn't setting the shutter speed too low. For posed portraits, I know I'm pretty safe at 1/125's, so that's my lower threshold most of the time. 1/125's is sufficient for most event shooting too...particularly if you're using a flash, since the flash will freeze your subject, but I might push the minimum up to 1/250's or something faster for a dance sequence.
But long story short, when ambient light drops, the minimum shutter speed setting is basically setting my shutter speed, and the ISO is automated.
Bonus: I have a focus recall setting mapped with a 1/1000s shutter speed, ISO auto, and aperture wide open...that way if something unexpectedly starts moving quickly, I can snap it with a fast shutter speed.
