    摘要: A focal length varying device for a camera comprises a photo taking optical system having a variable focal length; a discriminating device for discriminating whether or not adequate photographing is possible; and a system for automatically changing the focal length of the photo taking optical system on the basis of the result of discrimination made by the discriminating device.

    摘要: A watertight camera having incorporated therein a strobe device, wherein said strobe device and the camera body are connected with each other by a hollow pipe made watertight by an elastic member so that the strobe device is movable between a retracted position and a projected position, whereby said strobe device is held stationary either in the retracted position or in the projected position by the frictional force exerted from the elastic member to the hollow pipe.
