      La profondeur de champs est inversement proportionnelle \u00e0 la distance focale. Plus cette derni\u00e8re est \u00e9lev\u00e9e, plus la profondeur de champs est faible. Et plus elle est petite, plus la profondeur de champs est importante.<\/p>\n

      La profondeur d\u00e9pend \u00e9galement du diaphragme affich\u00e9 sur l’objectif. Plus le diaphragme est ferm\u00e9, plus la profondeur de champs est grande. Plus il est ouvert, plus la profondeur de champs est faible.<\/p>\n

      D\u00e9caler la bague de mise au point de 1 mm sur une courte focale (souvent en-dessous du 35 mm) ou sur un objectif ayant une ouverture \u00e9lev\u00e9e peut donc n’avoir aucune incidence sur la nettet\u00e9 de l’image d’un sujet (en l’occurrence la mire) \u00e0 une distance donn\u00e9e.<\/p>\n

      Dans ce cas, il peut \u00eatre int\u00e9ressant d’utiliser un ratio multiplicateur afin d’incr\u00e9menter le d\u00e9calage (en millim\u00e8tres) de la bague de mise au point.<\/p>\n

            D\u00e9but du test optique<\/h2>\n

            Les connaissances qui pr\u00e9c\u00e8dent acquises, le test d’une optique se r\u00e9v\u00e8lera d’autant plus facile et rapide.<\/strong><\/p>\n

            R\u00e9capitulons :<\/strong><\/p>\n

              \n
            • Placer la mire \u00e0 une distance de 50 fois la focale.<\/li>\n
            • Centrez pr\u00e9cis\u00e9ment la cam\u00e9ra \u00e0 l’aide du miroir de centrage.<\/li>\n
            • Collez un papier millim\u00e9tr\u00e9 sur le repaire fixe de la bague de mise au point.<\/li>\n
            • Assurez-vous de filmer correctement la mire et l’\u00e9chelle de calage optique (souvent positionn\u00e9 en-dessous de la mire).<\/li>\n
            • Notez la meilleure lecture \u00e0 l’oeil sur l’\u00e9chelle de calage optique.<\/li>\n
            • Munissez-vous d’un feutre effa\u00e7able ou des aimants fournis avec l’\u00e9chelle de calage optique afin de noter les informations sur l’\u00e9chelle de calage optique.<\/li>\n<\/ul>\n

              D\u00e9roulement du test :<\/strong><\/p>\n

              Le principe est de filmer une s\u00e9rie de petits films de 2 ou 3 secondes en d\u00e9calant \u00e0 chaque fois la bague de mise au point. Ces films mis bout \u00e0 bout donneront un film d’une vingtaine de secondes permettant d’analyser pr\u00e9cis\u00e9ment le calage d’une optique et la r\u00e9solution d’un syst\u00e8me de captation.<\/p>\n

                \n
              • Placez l’aimant (fourni avec le papier millim\u00e9tr\u00e9 Pr\u00eat \u00c0 Tourner) ou bien cerclez \u00e0 l’aide d’un feutre la premi\u00e8re mesure sur l’\u00e9chelle de calage optique. Commencez par -5.<\/li>\n
              • D\u00e9calez la bague de mise au point de l’objectif en rapport avec ce chiffre. Prendre en compte le ratio multiplicateur.<\/li>\n
              • Enregistrez ou imprimez quelques images (2 ou 3 secondes).<\/li>\n
              • Cerclez la mesure suivante (-4), d\u00e9calez la bague de l’objectif, enregistrez \u00e0 nouveau quelques secondes.<\/li>\n
              • Faites cela jusqu\u2019\u00e0 +5. Vous obtenez un film d\u2019environ 30 secondes.<\/li>\n<\/ul>\n
