Sony F65, RED Dragon, ARRI Amira, Canon C500 and Panasonic VariCam 35 Go Head-to Head in Camera Tests

Geoff Boyle pits the Sony F65, RED Dragon, ARRI Amira, Canon C500 and Panasonic VariCam 35 in a series of extensive tests meant to reveal dynamic range and the cameras’ real Sxposure Index (EI).

He writes on News Shooter, “The results were interesting: they revealed that some manufacturers were being a little optimistic in their EI ratings. There’s actually no standard way of measuring this so who can fault a manufacturer for using a system that makes their camera look good? However, I’m not interested in what looks good on paper, I want to know how to expose the camera to produce the best pictures I can get from it. We had serious issues with one of the cameras: the Varicam didn’t produce the results that I expected and it has taken four months and the assistance of Nick Shaw to establish what the problem was. We now know that Panasonic and Resolve don’t mix properly: it looks like the rushes are in video range when they are in fact in extended range. A manual adjustment in Resolve fixes this. We also established that some cameras have not only very different colour responses in tungsten and daylight but that they also have very different EIs.”
