摘要： A zoom lens barrel has a lens unit with both functions of zooming and focusing, comprises a first cyindrical member having a zoom guide groove (or zoom cam) corresponding to a zooming orbit of displacement of the lens unit with both the functions of zooming and focusing and a second cylindrical member having a focus guide groove (or focus cam) for displacing the lens unit with the functions of zooming and focusing along an optical axis for focusing. The focus guide groove or focus cam is non-linear and has an area inclined with respect to the optical axis to permit the relative displacement of the first and second cylindrical members to each other in the optical axis direction necessary for the focusing of a given object to be held substantially constant irrespective of the status of zooming and also permit the displacement of the lens unit with both the functions of zooming and focusing for focusing to be varied according to the status of zooming.

摘要： A waterproof operation mechanism of an interchangeable lens barrel having an operation member which is rotatably set around a periphery of the interchangeable lens barrel. A button engages with the operation member such that the button penetrates the operation member and protrudes outward from the operation member. The button functions to fix the operation member at a predetermined rotation position and to release the operation member from the predetermined rotation position. The interchangeable lens barrel includes a knurled part around its periphery, the knurled part being made of an elastic material and having a protruding portion integrally formed therewith to cover the button. Further, the operation member includes a fitting groove on a periphery of the operation member to prevent the knurled part from being displaced in a direction of an optical axis of the lens barrel.

摘要： A lens barrel is provided with a detecting device for detecting whether a clutch device for effecting the AF mode/MF mode changeover of a focus adjusting mechanism is changed over completely to either mode. When the detecting device detects that the changeover is not complete, as due to the supply of electric power from the camera body being cut off, the clutch device is automatically brought to the change-over position of a selected mode in response to the next supply of electric power.

摘要： A clamping device for camera accessories includes a cylindrical adaptor member defining a lens hood. The inner periphery of the adaptor member is formed with an annular collar member which has an internal diameter smaller than the external diameter of a collar formed on the outer sleeve of a lens barrel along a V-shaped groove which is formed on the outer periphery of the outer sleeve. The collar member serves to prevent the hood from connecting with the lens barrel at an undesirable position.
