What is a 50mm lens good for?

50mm lenses have a quick maximum aperture and are therefore considered fast lenses. The most basic 50mm lenses are generally F1. 8 in aperture, which is a relatively wide opening. In other words, they are excellent for low-light photography (e.g., low-light portraiture or interior shooting), as they enable more light to reach the camera’s sensor than traditional lenses.

What does F mean in lenses?

The brightness of the picture that goes through the lens and is captured by the image sensor is controlled by the aperture. An aperture’s size is determined by the number of stops it has. The higher the f-number, the narrower the aperture and the less light that passes through the lens; the lower the f-number,the bigger the aperture and the more light that goes through the lens.

Which lens is best for beginners?

The brightness of the picture that goes through the lens and lands on the image sensor is controlled by the aperture setting on the camera. With a higher f-number, the aperture is narrower and thus less light is sent through the lens; with a lower f-number, however, the aperture is bigger and hence more light is transmitted through the lens.
