What's the difference between telephoto lens and telephoto lens? What are their advantages and disadvantages?

1, the focal lengths of short-focus lenses and telephoto lenses are different.

2, the use of different scenes, short-focus lens is suitable for shooting close-range, telephoto lens is suitable for shooting long-range.

Advantages and disadvantages:

The telephoto angle is small, but it magnifies the subject and can shoot distant objects, such as the moon. In addition, telephoto can get a picture with shallow depth of field, similar to a large aperture. However, the disadvantage is that it is large and heavy, and a tripod is generally needed to obtain a stable image.

Standard lens and wide-angle lens are easier to operate, hand-held shooting can also get clear imaging, and the viewing angle is large, so it can shoot a wider range of scenery, which is most suitable for panoramic shooting and street sweeping.

Extended data:

When buying a wide-angle digital camera, we should not only pay attention to the overall performance of the camera, but also pay attention to its lens performance. Lens distortion is the first factor we need to consider. Generally speaking, wide-angle shooting is more prone to distortion, but photos taken by different cameras have different degrees of distortion. Generally speaking, the less distortion, the better.

Secondly, pay attention to the resolution of the picture. Due to the limitation of cost, the lens quality of digital cameras is often inferior to that of professional SLR lenses, especially the edge resolution of photos may be significantly reduced, and a good wide-angle digital camera can be controlled relatively well and the picture looks clearer.

And anti-glare ability. Because the viewing angle is very large at a wide angle of 28mm, it is easy to encounter backlight or side backlight. If the camera lens has poor anti-glare ability, ugly spots will appear on the photo, and even light rush will appear. Of course, purple edge, dispersion and so on are also our key concerns.
