WebThe f-number is commonly indicated using a lower-case hooked f with the format f/N, where N is the f-number. In optics, the f-number of an optical system such as a camera lens is … The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically ignored in photography, where f-number is often used regardless of the distance to the object. In optical design, an alternative is often needed for systems where the object is not far … See more 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 … See more The f-number N is given by: where $${\displaystyle f}$$ is the focal length, and $${\displaystyle D}$$ is the diameter of the … See more Depth of field increases with f-number, as illustrated in the image here. This means that photographs taken with a low f-number (large aperture) will tend to have subjects at one … See more The camera equation, or G#, is the ratio of the radiance reaching the camera sensor to the irradiance on the focal plane of the camera lens: where τ is the transmission coefficient of the lens, and the units are in inverse steradians 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 … 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 mm wide open, which translates into the … See more The system of f-numbers for specifying relative apertures evolved in the late nineteenth century, in competition with several other systems of aperture notation.

F値 （エフち、英: F-number）とは、レンズの焦点距離を有効口径で割った値であり、レンズの明るさを示す指標として用いられる。F値が小さいほどレンズは明るく（=レンズを通る光量が多い）、シャッター速度を速くできる。 F値のFとは「焦点の」を意味する"focal"から来ている。Fの後に数字を続けて（例：F2）表記する。なお、レンズの有効口径を用いて明るさを表現するこ … WebAn f/0.9 lens must allow 1.5 more stops (more than 2x as much light) than an f/1.4 lens, and the physical size of the aperture to achieve that often requires a larger lens barrel diameter. Increasing the barrel diameter requires, at the very least, a larger front element, which can quickly add to the cost of a lens.

WebIn numerical analysis, the condition number of a function measures how much the output value of the function can change for a small change in the input argument. This is used to measure how sensitive a function is to changes or errors in the input, and how much error in the output results from an error in the input. phoenix blazing pixelmon downloadWebThe f-numberof an optical system(such as a camera lens) is the ratioof the system's focal lengthto the diameter of the entrance pupil.[1] It is a dimensionless numberthat is a quantitative measure of lens speed, and an important concept in photography.
