This is a dynamic range test and comparison between the Sony A7S, Arri Amira, Panasonic GH4, Canon C300, Canon 5D mark III and Canon 1D C. The dynamic range is the range in luminance any given camera can capture. More range allows for more flexibility in post production and usually provides a more natural and hence more cinematic end result. What is the cinema5D test lab? cinema5D has established their own scientific testing facility to accurately measure and evaluate the performance of cameras. As a platform for reviews about cinematic cameras we strive to provide objective comparisons and share insights to help you choose the right camera for your projects.
