How many meters can the telephoto lens of a SLR camera shoot at the farthest?
You can shoot objects thousands of meters away from yourself.

The smaller the focal length, the more picture content can be accommodated; The greater the focal length, the closer the subject is.

The ultra-wide viewing angle of 8mm reaches 180 degrees; The focal length of 50mm is closest to the viewing angle of human performance, and the fixed focus of 50 is the standard lens; The viewing angle of 300mm is only 8 degrees.

Lens focal length classification

According to the different focal lengths, we divide the lenses into wide-angle lenses, standard lenses and telephoto lenses.

The focal length of wide-angle lens is less than 35mm, which is suitable for shooting scenery.

The focal lengths of standard lenses are 35mm, 50mm and 85mm, which are suitable for shooting people.

The telephoto lens has a focal length greater than 135mm, which is suitable for shooting wild animals and other long-distance shooting.

Extended data:

Shooting with a long focal length lens has the following characteristics:

Small angle of view

Therefore, the spatial range of the shooting scene is also small, and the shot image is larger than the standard lens at the same shooting distance, which is suitable for shooting the details of the distant scene and shooting the subjects that are not easy to get close to.

Short depth of field

So you can highlight the subject in a messy environment. However, it brings some difficulties to accurate focus adjustment. If the focus is slightly inaccurate when shooting, the subject will be blurred.

Poor perspective effect

This kind of lens has obvious characteristics of compressing spatial depth and exaggerating background.
