Field of view (FOV) is the open, observable area a person can see through their eyes or via an optical device, such as a camera. In the case of optical devices, FOV is the maximum area that the device can capture. In other words, it answers the question: "How much can the device see?"
What is 35mm field of view?
The field of view for a 35mm Nikon lens turns out to have a horizontal FOV of 54.5 degrees, 37.8 degrees of vertical range, and 63.4 degrees diagonally. This is the maximum area your camera can “see.”
What is FOV and camera FOV?
Field of view is the extent of the observable world that is seen at a given time either through someone's eyes, on a display screen, or through the viewfinder on a camera. Field of view (FOV) also describes the angle through which one can see that observable world.
What is the field of view of a human?
Each eye alone gives us roughly a 130-degree field of vision. With two eyes, we can see nearly 180 degrees. Most of that field is what's called a Cyclopean image -- the single mental picture that a Cyclops might see. But that single image, created by two eyes, has both range and depth.
