Why can't the lens focus when it is close to the subject?

Because most handpiece have that closest focal length,

There is a "φ" symbol in the lower right corner outside the shoulder screen.

This is the position of the camera's photosensitive element.

The nearest focal length is the distance from the position of this sign to the subject.

Generally, the nose needs this distance to be above 30cm.

If you need to shoot a closer object, you need to consider using a macro lens.

The closest focal length of the macro lens will be closer.

With 7 years of photography experience, the photographer's pure manual code word is expected to be adopted!
