Whether you ’re shopping for a new camera , lens or even a smartphone , you may have come across the acronym FOV .
FOV stands for field of view , but what does this actually think ? Keep reading to discover everything you require to interpret about FOV in photography .
What is FOV?
FOV – or field of operations of view – is a term used to indicate just how much of the environment can be seen through a tv camera at any given meter .
The orbit of view is determine by the size of the sensor and the focal length of the lens system attached to the photographic camera . However , photographers can well narrow or expand the FOV by changing out their lens .
The same live for wandering photography when moving between the multiple sensors on a phone . For illustration , ultra - encompassing angle cameras typically have a wider field of view than all-embracing , telephoto or macro I .
When it come to knowing which lenses will give what solution , photographers and camera troupe employ stage to describe different fields of position . high number betoken a wider FOV , while lower issue refer to a more minute FOV .
The human eye can in reality pick up around 180 degrees ( due to the fact we have two of them ) , but this is rarely matched in picture taking with fish - oculus lenses being the exception .
To take an instance from mobile photography , theSamsung Galaxy S23 Ultrahas three rear cameras : one wide of the mark angle sensor with an 85 - degree FOV , one extremist - wide with a 120 - degree FOV and a telephotograph sensor with a 36 - degree FOV . In this instance , the ultra - wide of the mark camera has the blanket FOV , think this camera is able to fit more of a scene into the frame .
The same goes for the interchangeable lenses on great DSLR and mirrorless cameras . Here , the exact field of view will depend on the camera and focal length of the lens used but , generally verbalize , a 24 mm lens will have a wider FOV than a 50 mm lens , which in good turn will have a broad FOV than a 200 millimetre lens .
you may see how the FOV varies across Nikon ’s FX - format crystalline lens in the diagram below .
