Photographic macro ring

Camera aperture size has nothing to do with shooting macro!

Aperture determines depth of field, large aperture is shallow depth of field, and small aperture is large depth of field.

Macro is the fine focusing distance, and macro refers to the closest focus and maximum magnification of the lens.

If you take a macro, you can't summarize the depth of field. Generally, the macro is the aperture of F2.8, and the depth of field is relatively shallow at 1: 1 magnification. Of course, you can use the aperture of F2.0 and choose a large aperture. Low-end SLR is difficult to focus, so we use a large depth of field and a small aperture. But it still depends on the subject matter and environment you want to shoot, and you can't generalize.
