Quick Guide: About Sensor Channel
Sensor Channel are the output data lane from sensor… 8 is better than 4 since it can transfer more data at the same time….The faster the camera can get the data off the sensor the faster it can fire the next shot.. resulting more fps (frames per second) in continuous brust/shooting mode.
