I try, of course, to photo outside so I will gain the light and movement as much as possible.
Scene 1: A tree in the wind


I took this photos in a very windy and cold day, the leafs here didn't stop moving for a second. Except the obvious difference we see here in the photo lightning, we can see as well that the the medium sensitivity photo has much more depth.
Scene 2: A bus in the street


Again, the movement is much more spotted in the higher ISO.
Scene 3: Ad in the wind


in this photo I think the higher sensitivity photo 'wins' in all categories and there is no advantage to the medium sensitivity one.
Scene 4: fancy car
Here I wanted to test the sensitivity on a still scene. You can see here too that the car itself looks better and lighter in the higher sensitivity photo but the background is clearer in the medium sensitivity one.
Scene 5: in the park
in this set I think the only difference is in the light of the photo without other difference in the depth. I personally prefer the medium sensitivity photo.
Scene 6: palace
In this picture it is obvious that higher sensitivity is required.
