Abstract
Eccentricity between an external knob and camera casing is accommodated by providing a flexible rubber ring between the two which will bend during a change in their relative positions so that a good seal is continuously maintained. Sealing can also be enhanced by extending the rubber gripping ring around the circumference of the knob down to the camera casing so that the sealing and operating rings are integral.
