An improved lens mount and related lens and lens barrel positioning methods are provided. In one example, a lens mount for use with a miniature camera can include a ring member having a substantially cylindrical interior surface defining a substantially cylindrical interior space. A plurality of elongate ribs are disposed on the interior surface of the ring member and are adapted to exert pressure against an external surface of a lens barrel received by the ring member. In another example, a method of positioning a lens barrel includes inserting a lens barrel into a ring member having a substantially cylindrical interior surface. Pressure can be exerted against an external surface of the lens barrel from a plurality of elongate ribs disposed on the interior surface of the ring member. The pressure can prevent rotation of the lens barrel along at least three axes of rotational freedom.
