The focal length of a lens is directly related to its magnification power. A shorter focal length results in a wider field of view and less magnification, while a longer focal length results in a narrower field of view and greater magnification.

Focal length equationfor lenses

The size of the image sensor can affect the effective focal length of a lens. A larger sensor will capture a wider field of view and result in a shorter effective focal length, while a smaller sensor will capture a narrower field of view and result in a longer effective focal length.

Focal lengthof convex lens

The focal length of a lens is a fixed characteristic and cannot be changed. However, the field of view and magnification can be altered by using different lenses or adjusting the distance between the lens and the image sensor.

Focal length can be calculated by dividing the distance from the lens to the image sensor (or film) by the distance from the lens to the subject. This is known as the thin lens equation: 1/f = 1/di + 1/do, where f is the focal length, di is the distance from the lens to the image sensor, and do is the distance from the lens to the subject.

Focal lengthof lens formula

Focal length is a measurement of the distance between the center of a lens and the point where light rays converge to form a clear image. It is typically measured in millimeters (mm) and is an important factor in determining the magnification and field of view of a lens.
