A waterproof camera to which an interchangeable lens unit having a waterproof construction is mounted. The waterproof camera has a lens mount provided in a camera body and to which the interchangeable lens unit is removably mounted, a ring-shaped flange provided in the lens mount and which positions the interchangeable lens unit relative to the camera camera body, an engaging member provided at an outer circumference of the ring-shaped flange and which engages with the outer circumference of one end of the interchangeable lens unit, and a waterproof member which is in pressing contact with an area of engagement between the engaging member and the outer circumference of one end of the interchangeable lens unit and prevents water from penetrating in the area of engagement.

A camera is capable of both silver-halide shooting, through which object images are recorded on silver-halide film, and video shooting, although its distance measurement device is placed substantially in the same way and its mirror box has substantially the same size as in ordinary single-lens reflex cameras. In this camera, a pellicle mirror splits the light flux having passed through a taking lens into a first light flux and a second light flux, and a rotatable mirror switches the subsequent path of the second light flux between the optical path for a third light flux and the optical path for a fourth light flux. The pellicle mirror, through its light flux splitting function, directs the first light flux to a silver-halide shooting system, and directs the second light flux to the rotatable mirror. The rotatable mirror, through its optical path switching function, either directs the third light flux to an optical viewfinder system, or directs the fourth light flux to a video shooting system.

A radio communication terminal 100 includes: a first storage unit 1171 configured to store a PRL list L1 used for connection to a communication provider-provided WLAN provided by a communication provider, a content of the first storage unit 1171 being rewritable by the communication provider; and a second storage unit 1172 configured to store a user registration list L2 used for connection to a user-registered WLAN registered by a user of the radio communication terminal, the second storage unit 1172 being rewritable by the user. The radio communication terminal 100 selects any one of the communication provider-provided WLAN and the user-registered WLAN, based on the PRL list L1 and the user registration list L2.

An illumination apparatus including: a power supply circuit which outputs a DC power obtained by rectifying an AC voltage and stepping up the rectified voltage; a light source unit having semiconductor light emitting elements turned on by the DC power; and a housing formed of a conductive material that is grounded through a ground path and on which the power supply circuit and the light source unit are mounted. When one of power feed lines is cut off, the light emitting elements are supplied with an AC power from an AC power source through the ground path and a stray capacitance formed between the light source unit and the housing, and a forward voltage of the light emitting elements has a light emission level hardly recognizable.

A zoom lens including first, second, and third lens groups having positive, negative, and positive refractive powers, respectively, which are arranged in that order from the object side to the image side such that, when zooming from wide-angle to telephoto, the first lens group moves to the object side, and spacings between the lens groups change. The third lens group has at least two lenses including a first lens, which is a positive lens arranged closer to the object side than the other lenses of the third lens group. Blur correction is performed by moving the first lens perpendicularly to the optical axis. The third lens group is configured such that the following conditional expression is satisfied: 0.3

A pneumatic tire has a tread surface is provided with a groove portion, and a land portion sectioned by the groove portion. In wall surfaces facing the groove portion in the land portion, an inside wall surface facing an inner side at a time of being installed to a vehicle is formed by a zigzag surface, and an outside wall surface facing an outer side at a time of being installed to the vehicle is formed by a flat surface.
