5. Profondeur de champ

Les échelles de profondeur de champ sont gravées à côté de ligne de repère des distances. Lors de prises de vue très rapprochées, Ia profondeur de champ est si faible qu’il vaut mieux se reporter au tableau de profondeur de champ (page 150). Si votre boîtier comporte la commande/ le poussoir de contrôle de profondeur de champ, ou le levier de contrôle de profondeur de champ, vous pouvez tester la profondeur de champ dans le viseur.
