Field of View (FOV)

Field of view (FOV) describes the angular extent of what a camera lens can see — essentially, how wide or narrow the camera's "window" is. A wide field of view captures a broad sweep of the environment, fitting more into the frame. A narrow field of view behaves like a telescope, magnifying a distant subject while seeing only a small slice of the surrounding space. FOV is determined primarily by the lens's focal length relative to the camera sensor size: short focal lengths (16mm, 24mm) produce wide fields of view; long focal lengths (100mm, 200mm+) produce narrow fields of view with telephoto compression.

The human eye has an FOV of roughly 135 degrees horizontally, though the area of sharp focus is much narrower. A 50mm lens on a full-frame camera produces an FOV roughly equivalent to the human eye's natural perspective, which is why 50mm focal lengths feel "natural" and undistorted. Wide-angle lenses exaggerate perspective, making nearby objects appear larger and more imposing while the background seems to recede. Telephoto lenses compress perspective, flattening the apparent depth between subject and background and making background elements appear larger and closer than they are.

For B2B video, FOV choices have both aesthetic and practical implications. Wide-angle lenses (24mm–35mm) are good for small spaces where the camera can't move far from the subject, but they distort faces at close distances (the "GoPro face" exaggeration). Mid-range lenses (50mm–85mm) are the standard for talking-head interviews — they produce flattering, natural-looking facial rendering without perspective distortion. Telephoto lenses (100mm+) are useful for compressing a busy background into abstract bokeh, but require more physical distance from the subject to achieve correct framing, which isn't always available in tight production environments.
