This is a rolling shutter comparison between the new Sony A7S, the Arri Amira, Panasonic GH4, (Canon C300), Canon 5D mark III and Canon 1D C. In the first part in this series of tests we compared the usable dynamic range of the A7S and found that it comes surprisingly close to the dynamic range of the Arri AMIRA (find the dynamic range test here). Rolling shutter is a phenomenon where straight vertical lines look bent on moving objects, or a “jello effect” appears when the recording device itself is in motion. It is a common issue with CMOS sensor cameras that read out a frame line by line over a certain period of time. A sensor with a global shutter however reads out the entire image at once, avoiding the rolling shutter effect altogether. A severe rolling shutter can be disturbing in certain shooting scenarios.Read more
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.Read more
