F1.8

What is F1.8?

F1.8 refers to a specific aperture setting on a camera lens, where the aperture is wide open and has a diameter that is 1.8 times the focal length of the lens.

A lens set to F1.8 allows a significant amount of light to enter the camera, making it ideal for shooting in low-light conditions or achieving a shallow depth of field with a blurred background. Lenses with a wide maximum aperture of F1.8 or larger are often referred to as "fast" lenses because they allow for faster shutter speeds and lower ISO settings, which can improve image quality and reduce noise in low-light situations. F1.8 is a popular aperture setting for portrait, wedding, and street photography, as it can produce attractive bokeh and isolate the subject from the background. The specific aesthetic characteristics of an image produced at F1.8 will also depend on the lens design and other factors such as distance to subject and the camera's sensor size.
