Summary:ABSTRACT OF THE DISCLOSURE A lens assembly includes a lens with a lens barrel and a lens mount assembly. The lens mount assembly includes a lens mount barrel and a protrusion. First threads on the lens barrel and second threads on the lens mount barrel are shaped to permit the lens barrel and the lens mount barrel to be screwed together. The protrusion is positioned to interfere with at least one of the first and second threads as the lens barrel and the lens mount barrel are being screwed together. This interference resists rotation of the lens barrel relative to the lens mount barrel, thereby reducing the likelihood that the lens will be inadvertently screwed or unscrewed away from a desired depth. Date Recue/Date Received 2020-11-18 ABRÉGÉ DE LA DIVULGATION Un ensemble dobjectif comprend un objectif avec un ensemble de monture dobjectif et de barillet de lobjectif. Lensemble de monture dobjectif comprend un barillet de monture dobjectif et une saillie. Un premier filetage sur le barillet de lobjectif et un deuxième filetage sur le barillet de la monture dobjectif ont des formes qui permettent au barillet et à la monture de lobjectif de se visser lun sur lautre. La position de la saillie lui permet de bloquer au moins un des deux filetages au moment de visser le barillet de lobjectif à la monture dobjectif. La saillie fournit ainsi une résistance à la rotation du barillet de lobjectif par rapport au barillet de la monture dobjectif, ce qui réduit la probabilité que lobjectif tournera de manière à perdre la profondeur souhaitée.
