How are camera lenses made?

1. Professional camera

Professional cameras use the image conversion of the lens group to achieve the best effect of the current lens' applicable focal length. After the light passes through the camera lens and reaches the reflector, it is refracted to the focusing screen above and forms an image. Through the eyepiece and pentaprism, the photographer can see the outside scenery in the viewing window.

2. Semi-professional camera

The lens of a quasi-professional camera can be replaced by adding other lenses or lenses to achieve the effect of replacing the lens. The price of a quasi-professional camera plus a relatively complete set of additional lenses and lenses is roughly more than 10,000 yuan, which is basically equivalent to the price of an entry-level professional SLR camera body. Therefore, quasi-professional cameras are most suitable for high-end individual users with certain photography skills.

3. Ordinary cameras

Ordinary camera lenses cannot be replaced, nor can other lenses or lenses be attached. Most operations are completed automatically.

Camera lens maintenance

Generally speaking, some dust on the surface of the lens will not have much impact on the clarity of the image. . Therefore, if it does not affect the shooting effect, try not to wipe the lens.

If there is fog on the surface of the lens, it is best to turn the camera over so that the camera lens is facing up and let the fog disperse naturally. If you must wipe it, it is best to use special lens paper to "dip" the surface of the lens.
