What is the control of the gear for fixed focus lens? It seems that if you adjust the aperture, the autofocus of the fuselage will be adjusted to what it thinks is good. What do you shoot when you go out in the street? Use A gear: First, the lens should be set to "A" gear, which is the gear next to the minimum aperture.

Second, the fuselage turntable should be adjusted to the position of A or AV.

Third, after you adjust the aperture, the automatic exposure of the fuselage will change, but the aperture will not change. Unless your settings are beyond the automatic range of the fuselage, such as poor light, you adjust the aperture very small (above 22) and so on. ). In the range of the camera, when the sensitivity is set to the highest and the shutter is set to the slowest, it is considered underexposed, so that the body will be adjusted to the state it thinks is good (the longest exposure time it can bear).

Fourth, in SLR, the viewfinder is not what you see is what you get. The default is the maximum aperture of the lens, and you can set the aperture to take pictures. If the camera has an aperture preview lever, it can be used to see the effect. But to be honest, if you want to see the effect of different apertures in the viewfinder, other things, such as blurred depth of field, are not very nice except brightness, unless your eyes are good, or you are shooting close objects.

Fifth, if you want to shoot a street shot, you will generally adjust the aperture to the second gear behind the maximum aperture of the lens on the fuselage, and the effect is ideal.
