Is telephoto suitable for portrait photography?

Telephoto shooting is ok, and the blur effect is good. But using telephoto also has advantages and disadvantages.

Benefits: 1 Depth of field is inversely proportional to focal length. The longer the focal length, the shallower the depth of field (so-called background blur).

2. The longer the focal length, the less likely it is to be distorted.

Disadvantages: 1 The longer the focal length, the higher the shutter speed and the more difficult it is to control.

2. Most telephoto lenses are bulky and inconvenient to carry.

3. Shooting with a telephoto lens is far away from the model and it is not easy to communicate with the model.
