Rolling shutter has been the bane of DSLR and mirrorless video shooters since the beginning. In fact, for users of just about any camera with a CMOS sensor. This is all down to how CMOS sensors traditionally work, scanning the scene line by line. Each line is captured at a slightly different point in time, so as you pan, it appears that subjects are leaning or wobbling. Hence it’s become affectionately known as the “jello effect”.
That may be all set to change, though, thanks to a new breakthrough from Sony who has developed an entirely new CMOS sensor with a global shutter function. Announced last week at the International Solid-State Circuits Conference (ISSCC) in San Fracisco, the new sensor features a pixel-parallel analogue to digital converter. This means that it can read the data from all of the pixels simultaneously.
