ABSTRACT:
A lens barrel includes a frontmost lens, a lens supporting annular member for supporting the frontmost lens to prevent the frontmost lens from moving rearward from a predetermined axial position relative to the lens supporting annular member, a lens fixing ring for fixing the frontmost lens to the lens supporting annular member, an annular abutting surface which abuts against a circumferential portion of a front surface of the frontmost lens and is formed on the lens fixing ring and a coating applied to the annular abutting surface. The coating is positioned between said annular abutting surface and said circumferential portion to provide a substantially watertight seal.
