光圈

珠江镜头的光圈环,上面显示可调光圈系数2-16
 f/32 小光圈,深景深
 f/5.6 大光圈,浅景深

光圈英语:Aperture),是照相机上用来控制镜头孔径大小的部件,以控制景深、镜头成像质素、以及和快门协同控制进光量。有时也表示光圈值的概念。表达光圈大小用f值表示,对于已经制造好的镜头,不能随意改变镜头的直径,但是可以通过在镜头内部加入多边形或者圆型,并且面积可变的孔状光栅来达到控制镜头通光量,这个装置就叫做光圈,光圈f值=镜头的焦距/光圈口径。 光圈对照片的影响:光圈越大进光量越大,景深越小,f值越小。

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. The aperture determines how collimated the admitted rays are, which is of great importance for the appearance at the image plane. If an aperture is narrow, then highly collimated rays are admitted, resulting in a sharp focus at the image plane. If an aperture is wide, then uncollimated rays are admitted, resulting in a sharp focus only for rays with a certain focal length. This means that a wide aperture results in an image that is sharp for things at the correct distance. The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time). In the human eye, the pupil is the aperture.
