Assignment 3: Field of View

The field of view is that part of the world that is visible through the camera at a particular position and orientation in space.  This is also known as an angle of view which includes objects outside that your lens together with the camera can see and capture from left, right, centre, top and bottom. Furthermore, the actual field of view is always what the camera captures, not necessarily what you see inside the viewfinder.  For example, some DSLR cameras, have less than 100% viewfinder coverage, which means that what you see inside the viewfinder is actually less in size than what the final image will be. For instance, if you shoot with the Nikon D90 DSLR that has 96% viewfinder coverage, what you see inside the viewfinder is going to be about 4% less than what the camera actually captures. Hence, the actual field of view is always what the camera captures, not necessarily what you see inside the viewfinder.

Below is a typical example of differences in field of view between 70 and 400mm:

The top-left 70mm image looks almost “wide”, while the 400mm image shows a much greater magnification with a much narrower field of view.
