ABSTRACT:
A lens assembly includes a barrel, the internal surface of which is formed with a lens abutment against which the peripheral edge of the front surface of a lens is supported. The free end of a preferably flexable lens fixing member is disposed to exert pressure on the peripheral edge of the rear surface of the lens, and its rear end is engaged with the barrel to fix the lens in position.
