All cameras with the exception of the C200 and Ursa Mini-Pro were tested using a Fujinon HK 4.7 * 18 and focal length varied and noted below to match a "standard" S35 frame size shot with a 50mm. The C200 and Ursa used a Canon CNE 50mm due to the EF mount.
The cameras, where appropraite, were set to whatever resolution came closest to a "standard" S35 frame so, for example, the Helium was shot at 7K.
The only objective here is to establish the true ISO of any camera and to find a precise usable dynamic range. I emphasise usable as although more may be measurable it may be too noisy to use or the colour may change too much.
