While dated, they do show a range of comparisons that are of interest, and help in understanding some of the variations and limitations with digital cinematography.

These tests were performed in conjunction with Geoff Boyle's CML (see logo/link to the right - and make sure you visit for all the latest Cinematography information and related discussions!).

All Charts were lit to T2 and T22 at an ISO of 320 and all cameras were fitted with Zeiss lenses.

With the chart lit to T2 a series of exposures were made at half stop intervals to T22.

The with the chart lit to T22 a series of exposures were made at half stop intervals to T2.

What can be seen is the comparative latitude similarity of the Viper and f23, while the D-20 poor shadow response also stands out (however, it has to be stressed that since this test was done Arri have updated all D-20 cameras to D-21 status, and the difference is amazing - I'm now a real fan of the D-21). It is also apparent that although all the cameras were all rated to 320 ISO the reality is very different.

These tests are now rather old, and the advance in digital cinematography has been fast and furious. A new set of tests really do need to be done!
