What should I set?
Say what the light is doing and how you want the picture to look. The ISO and the shutter speed are what is left over.
- ISO
- 10000
- Shutter
- 1/160
- Aperture
- f/13
1/160 is as slow as this goes, 90mm needs 1/160 to stay sharp in your hands, so the ISO is whatever the light leaves.

Your camera
Set your body in the masthead and the ISO stays inside what it will actually give you, and this says whether the ISO you have landed on has greyed DR400 out in the menu.

Every pair is the same amount of light at ISO 10000. What changes is how much is in focus and how much of the movement you keep.
