Abstract

L'invention concerne des premiers moyens de commutation servant au démarrage du fonctionnement préparation prise de vues et des seconds moyens de commutation servant au démarrage du fonctionnement prise de vues, le réglage préliminaire de focalisation étant répétitif jusqu'à ce que les premiers moyens de commutation soient actionnés. L'appareil photographique comprend des moyens de prise de vues pour le démarrage d'un réglage de focalisation d'une plus haute précision que le réglage de focalisation préliminaire, en raison du fonctionnement préparation prise de vues résultant de la mise en action des premiers moyens de commutation, et pour effectuer la prise de vues pendant que la commutation se situe entre un premier et un second mode. Dans le premier mode, lorsque les seconds moyens de commutation sont actionnés, la prise de vues s'effectue une fois que le réglage de focalisation haute précision est terminé. Dans le second mode, lorsque les moyens de commutation sont actionnés, la prise de vues s'effectue, suivant le résultat du réglage de focalisation, maintenu avant le fonctionnement des seconds moyens de commutation. De cette façon, en effectuant la prise de vues dans le second mode, par mise en action des seconds moyens de commutation, la prise de vues est réalisée, suivant le résultat du réglage de focalisation, maintenu avant le fonctionnement des seconds moyens de commutation. Il est ainsi possible de réduire le retard au déclenchement. En outre, du fait que le retard au déclenchement est réduit, il est possible d'effectuer la prise de vues à une synchronisation demandée par l'utilisateur, sans manquer un créneau d'ouverture de l'obturateur.
