Some cameras give you a staggering range of ISO values, for example, the Sigma fp.

From Sigma's specs.

ISO Sensitivity (Recommended exposure value) Base ISO

[Still]
ISO 100,640
[Cine]
CinemaDNG 12 bit / HDMI RAW:ISO 100, 3200
MOV / CinemaDNG 10 bit, 8 bit, HDMI 4:2:2 8 bit:ISO 100, 640

Settable Range

ISO 100-25600 / Expanded sensitivity ISO 6, 12, 25, 50, 51200, 102400

..............

I'd be happy with ISO 25 on a Fujifilm body but ISO 6 would be amazing, but using it requires taking multiple frames.

I would love a real, bonafide iso 25 or 12. It makes studio work much easier

I'd be happy with base iso 100. I'd be overjoyed with base iso 50.
