Some focus wide open then stop down to take the shot.

Others focus at the set aperture (for example the Laowa 25mm which doesn't "talk" to the camera at all).

Of course, the closer you have to be to your subject, the less light is going to illuminate the subject hence the need for elaborate lighting set-ups in the studio and flash w/diffusers in the field.
