The same goes for the interchangeable lenses on larger DSLR and mirrorless cameras. Here, the exact field of view will depend on the camera and focal length of the lens used but, generally speaking, a 24mm lens will have a wider FOV than a 50mm lens, which in turn will have a wider FOV than a 200mm lens.

Nature photography requires an assortment of lenses depending on the subject. Typically normal to wide angle lenses are used for landscape photos and very long telephotos are used for wildlife. These eight photos were taken from the same place with different lenses. The subject is Longs Peak from Upper Beaver Meadows in Rocky Mountain National Park. 24mm 35mm 50mm 100mm 200mm 400mm 800mm 1200mm "I want to take a bluebird picture. What lens should I use?" It is a symptom of bird photography that your lenses never seem to be long enough. This is because birds are so small. When photographing large animals, a 400mm gives you decent image size from a reasonable distance. But remember, an elk is six or seven feet tall. A bird is barely six inches long, so when your subject is twelve times smaller, you have to be twelve times closer. As you can see, even a huge 800mm lens at the relatively close distance of 20 feet doesn't give the huge magnification you might expect. The field of view is about ten inches.

When it comes to knowing which lenses will give what results, photographers and camera companies use degrees to describe different fields of view. Higher numbers indicate a wider FOV, while lower numbers refer to a more narrow FOV.

To take an example from mobile photography, the Samsung Galaxy S23 Ultra has three rear cameras: one wide angle sensor with an 85-degree FOV, one ultra-wide with a 120-degree FOV and a telephoto sensor with a 36-degree FOV. In this instance, the ultra-wide camera has the widest FOV, meaning this camera is able to fit more of a scene into the frame.

The field of view is determined by the size of the sensor and the focal length of the lens attached to the camera. However, photographers can easily narrow or expand the FOV by changing out their lenses.

The human eye can actually pick up around 180 degrees (due to the fact we have two of them), but this is rarely matched in photography with fish-eye lenses being the exception.

Where do those numbers come from? Lenses are marked with a series of f-stops, each one lets in half as much light as the previous one. The light-gathering ability of a lens is determined by its area, and f-stops are determined by diameter. Area is related to diameter squared. The progression of f-stops, 1 - 1.4 - 2 - 2.8 - 4 - 5.6 - 8 - 11 - 16 - 22 - 32, are powers of the square root of 2. For a further explanation of f-stops, try this.
