The Panasonic LUMIX S1 full frame camera has fared very well in our dynamic range and latitude tests and we were eagerly waiting to see if it will do equally well in our rolling shutter test. Just as a reminder, this dreaded phenomenon is negatively affecting CMOS based cameras. Panasonic LUMIX S1 We have already published several articles on the new Panasonic S1, and the latest one which shows exceptionally good dynamic range and latitude (underexposure) results of the new VLOG profile can be found here. Now it is time to have a look at the dreaded rolling shutter, which is a negative side effect of CMOS based cameras. For fast moving subjects across the frame, rolling shutter causes distortions, like for example vertical lines that start to tilt. Another example is the “wobbly” feel of handheld footage shot without image stabilization. Rolling Shutter sample – When a straight object becomes not so straight anymore…. What is causing the Rolling Shutter Phenomenon? Rolling shutter occurs because the sensor read out happens from the top to the bottom of a frame with a certain finite readout speed (the rolling shutter value in milliseconds [ms]) as opposed to global shutter where the whole frame is being read at once. This basically means that line per line from top to bottom is exposed and read out. As it takes a while to do this, a change in the frame may have happened in this rolling shutter read out time window going from top to...
