Wanting to test the limits of the Z8, I took out my only FX lens: the Z 180-600 f/5.3-6.3, and went out to shoot some photos after 7:30 PM. The maximum ISO was 25600. Testing revealed that the most suitable, or in most cases, usable ISO range was around 12800 or 16000, so I set the automatic ISO limit to 16000. If ISO 16000 was still underexposed, it meant it was getting dark and time to go home.

Actually, I think a telephoto lens isn't necessarily bad, especially in picture 3; I took a picture of those three guys across the street.
