What does the s behind the aperture mean?

the s behind the aperture refers to the minimum aperture value on the camera lens. For example, the number 8 in f/8 and f/8 refers to the s behind the aperture. The smaller this value, the more light the lens passes through, so that the camera can get more light information and achieve a shallower depth of field effect. Therefore, photographers often choose a smaller aperture value when shooting portraits, macro and other photos that require strong subject and background blur.

in the actual shooting process, the s behind the aperture will also have a certain impact on the quality of the photo. Usually, the maximum aperture value of the lens is not the best choice. Because under the maximum aperture value, there are often cases of rough pixels and photophobia. Therefore, it is essential to choose the standard aperture value in different occasions. For example, when shooting scenery, street shooting and other scenes, you will need a smaller aperture value to ensure the overall clarity of the picture.

When buying a lens, photographers often consider the maximum aperture value of the lens. However, the choice of aperture value is not only a matter of the maximum aperture value, but also needs to consider the stability of aperture value, lens quality and other factors. Therefore, in addition to the reference price factor, it is more necessary to pay attention to the actual effect of the lens, more suitable for their own use environment and other factors to choose the lens that suits them.
