Lecture 16: Cameras and Lenses (17)

What part of the sensor allows it to maintain image quality when zooming in?


I think only digital zoom loses resolution/image quality when zooming in, since it is equivalent to simply taking the full-resolution "unzoomed" image and cropping in the part that you want zoomed. However, with optical zoom, the full resolution of the sensor is used to capture a small field of view due to the manipulation of light by the lens.
