WebThe focal length of the lens describes the distance between the lens and the focused image on the sensor. As light passes through the lens it will either converge (positive focal length) or diverge (negative focal length), however within cameras the focal length is predominately positive. WebBoth 35mm and 50mm are good focal lengths for photographing the people around you, street photography, and travel. 35mm is better suited to fast-moving subjects and scenarios where it might be trickier to nail focus. 50mm has a tighter field of view and is better for creating cinematic images using a shallow depth of field.

WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length … WebThe key is to understand that focal length is calculated by measuring the distance from the optical center of the lens to the image sensor, and this distance is measured in mm. The longer the focal length, the physically longer the lens will be. Lenses with a wider view will have a shorter focal length and are physically shorter by comparison.
