How good is the effect of taking portraits with a 50mm C-frame camera?

The 50mm fixed focus lens is the most affordable in terms of price. When paired with an APS-C format camera, it provides an equivalent focal length of 75-80mm. If paired with a large aperture, it is very suitable for portrait creation. This focal length is the golden focal length for portrait photography, because it has reached a medium-long focal length, and the depth of field control ability is already very powerful. Almost any cluttered background or environment is blurred. Creates a great blur effect that separates people and scenes.

The disadvantage is that it is difficult to compose pictures in APS-C format with a 50mm fixed focus lens. The main problems are:

1. If you want to ensure the ratio of the subject to the blank space in a full-body photo, the distance of the lens It feels relatively far away, giving people a feeling of being at a distance. If you get closer, you will feel that the characters are trapped, which is very depressing.

2. In addition to the central composition, there are too many elements on the other side of the edge composition, or there is too much unbalanced white space. When the bust is shot vertically, the legs are amputated. If the viewpoint is raised, there will be too much blank space in the head.

3. It feels too flat, has no sense of novelty, and loses interest.

4. The person in the photo looks a bit fat.

(In this case, side shots should be able to solve this problem)
