Control device for the focal control of variable focus lenses, commonly called zooms, of digital reflex cameras, also called DSLR. The device is comprised of a control lever affixed to a concave metal plate inserted into a closed circular rubber strip. The elasticity of the device means that it can be mounted on all brands and sizes of lenses. The pressure and adherence of the rubber strip onto the adjustment ring of the lens enable it to be rapidly moved from up to down and down to up using a control lever to reach the desired focus. The device is mounted and removed in a few seconds.
Dispositif de contrôle de focale pour les objectifs à focale variable, couramment appelés zooms, des appareils photographiques reflex numériques, aussi dénommés DSLR. Le dispositif est constitué d'un levier de contrôle fixé sur une plaque de métal concave insérée dans une bande de caoutchouc circulaire fermée. L'élasticité du dispositif fait qu'il peut être monté sur des objectifs de toutes les marques et de toutes les tailles. La pression et l'adhérence de la bande de caoutchouc sur la bague de focale de l'objectif permettent de la faire bouger rapidement de haut en bas et de bas en haut à l'aide d'un levier de contrôle pour atteindre la focale désirée. Le dispositif se pose et s'enlève en quelques secondes.
