What is the difference between anti-shake and anti-shake of SLR cameras?

1. Anti-shake: Use the movable parts in the camera, such as the lens group or the camera, to compensate the light path with hand shake, and minimize the blurred image caused by the photographer's shake during use.

2, no anti-shake: there are no moving parts inside, it is directly the SLR body.

Second, the use requirements are different.

1, anti-shake: the focal lens has a small viewing angle, and slight jitter will have a great impact on imaging. Large zoom lens and long focal length lens have higher requirements for anti-shake.

2. No anti-shake: the lens with short focal length has a large viewing angle, and the same degree of jitter has relatively little influence on the image sensor;

Third, the advantages and disadvantages are different.

1, anti-shake: anti-shake technology can solve the problem of hand shake well, and anti-shake technology will also reduce the clarity of imaging.

2, no anti-shake: it will not reduce sharpness, which may cause the picture to be blurred at that time.

Matters needing attention in the use of SLR cameras

1, try not to direct the hot sun.

Try not to direct sunlight or strong light when using digital cameras. Although SLR cameras only press the shutter for exposure, strong light has little effect on the sensor, but facing strong light for a long time is likely to damage the camera's metering system. The optical path of the card camera is facing the light source, and the sensor has been working. Facing the sun for a long time will cause the aging of the sensor, so try not to shoot the sun, especially the scorching sun at noon.

2. The card camera turns on "Sleep" and retracts the lens.

For the card machine with retractable lens, the retractable lens is very fragile. It is suggested to turn on the "sleep" function of the camera, let the lens retract automatically after a period of inactivity, close the self-contained lens cover to prevent the lens from being damaged and deformed due to unintentional collision, and touch the shutter to return to the shooting state.

Don't often unscrew the lens from the fuselage outdoors.

Don't often unscrew the lens from the fuselage outdoors, it will inevitably enter the dust. When replacing the lens, it should be carried out as far as possible in the case of less indoor dust. You can't change the lens after sweeping the floor or folding the quilt.
