In the below video, Movie Machine’s Rick Young explains how sensor size affects depth of field.
He writes, “Sensors come in many different sizes and the size of the sensor has a direct relationship to light sensitivity. Large sensors perform better in low light, and a large sensor creates a more shallow depth of field to the image. The critical factors affecting depth of field is the aperture setting on the lens, the sensor size, and the chosen focal length.”
