1. A lens assembly comprising:
a lens that includes a lens barrel, the lens barrel including first threads; and
a lens mount assembly including:
a lens mount barrel including second threads, wherein the first and second threads are shaped to permit screwing together of the lens barrel and the lens mount barrel by mating of the first and second threads; and
a plastic protrusion 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 in a manner such that an interference between the plastic protrusion and the at least one of the first and second threads resists rotation of the lens barrel relative to the lens mount barrel, and the at least one of the first and second threads being configured to force a deformation upon the plastic protrusion as the screwing together proceeds during the interference.
