The portrait shot by telephoto lens accounts for a small proportion in the image sensor.

The reasons are as follows:

1. The macro lens is specially designed to minimize the focusing distance and bring the photographer closer to the subject.

2. The most important imaging feature is the ability of "spatial compression".

3. The so-called space compression is to enlarge the foreground and compress the depth of field.
