What do P, S, A and M in Nikon camera mean respectively?

1, "s" shutter priority exposure mode: select s to control the shutter speed, and the aperture changes with exposure. Generally, the speed of shooting the motion shutter should be fast, and the speed of shooting the running shutter should be slow, in order to shoot the motion. ?

2. "A" aperture priority exposure mode: Select A to control the camera aperture, and the shutter speed changes with exposure. The aperture size can control the depth of field of a photo. Large aperture short depth of field, small aperture long depth of field. Use a large aperture to blur the background when shooting portraits, and use a small aperture to expand the depth of field when shooting landscapes. ?

3. "M" full manual exposure mode: If M is selected, the photographer can adjust all shooting parameters (aperture, shutter and sensitivity) to shoot. ?

4. Exposure mode of "P" program: similar to automatic shift, the shutter and aperture are set by the camera, but they can be adjusted by themselves. Select p, after the automatic metering is completed, the exposure will be recorded, and you can adjust the combination of shutter and aperture without changing the exposure.

5. The automatic transmission is fully automatic. The switches of AF and M are focus mode switches. If there is this switch on the installed auto lens, AF must be turned on to focus automatically. The knob with L is the focus lock switch. When you dial l, it is locked and the focus cannot be moved.

1 and SK refer to the multilayer coating of the lens. ASP refers to the use of aspheric lenses to improve the quality of wide-angle imaging.

2.DC refers to the front and back defocusing control loop, which uses artificially increased spherical aberration to change the front and back depth of field of the subject.

3.M/A means that you can change to manual focusing at any time without moving the switch key.

4.VR means that installing an electronic shock absorption system (the same as Canon's) can reduce the use of 3-speed shutters.

5.VRII refers to the second generation electronic shock absorption system, which can reduce the use of 4-speed shutter and is generally used for higher-level lenses.

6.SWM means that the lens focus motor is a quiet fluctuation motor to ensure the smooth and quiet autofocus operation of the lens.
