Just got a new D7100 and wanted to know what are the optimal ISO values. I searched but couldn't find an answer. Hence, I did this test. To me, these are the best ISOs for videos:
ISO 100, 200, 400, 800, 1600 and 3200.

Please download for better results.

Here are the settings:
FPS: 25, Shutter: 1/50, PP: Flaat_11, Fstop: 3.5, Lens: Nikkor 28-105 AF-D @28mm
