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 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.
Grade corrected for best exposure at whatever stop was nearest to "correct" and all other shots matched to that with offset level only to give G 128, no changes to colour.
