This can't be answered.
An analog camera has only so many LOR and the zoom will only go so far optically...digital has so many pixels and when you blow the image up, the pixel size starts to affect the scene and you start getting "pixel bleed" where smaller objects at distance are distorted by the relative size of the pixels vs. the FOV. Very common on wide megapixel cameras. Great for getting a large image and being able to zoom in on smaller areas, but the detail starts to suffer.
As Pete said, apples to oranges (or more so, lettuce).
