WebThe f/# (pronounced “F-number”) setting on a lens controls overall light throughput, depth of field (DOF), and the ability to produce contrast at a given resolution. Fundamentally, f/# … WebThe f-number (and hence the aperture) on lenses can be adjusted in discrete steps that are referred to as "f-stops". An f-stop represents a halving or doubling of the amount of light allowed through the lens, by halving or doubling the area of the aperture opening (as described in an earlier article in this series on aperture ).

In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative … See more The f-number N is given by: where $${\displaystyle f}$$ is the focal length, and $${\displaystyle D}$$ is the diameter of the entrance pupil (effective aperture). It is customary to write f-numbers preceded … See more The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system that blocks certain rays. The aperture stop is the aperture setting that limits the brightness of the image by restricting the input … See more Computing the f-number of the human eye involves computing the physical aperture and focal length of the eye. The pupil can be as large as 6–7 … See more The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically … See more Depth of field increases with f-number, as illustrated in the image here.
