Description

The present invention relates to a camera housing system, a camera housing, and a grip device suitable for underwater photography.

Normally, for taking underwater photographs, for example, a camera housing system in which a digital single-lens reflex camera or a mirrorless single-lens camera equipped with a lens selected from an interchangeable lens group is housed in a camera housing for underwater photography is used.

This camera housing system has a waterproof structure up to a predetermined water depth, and has a structure that allows the stored camera to be operated underwater. Further, in water, the color balance is lost due to the water absorption characteristics and the amount of light is small, so an underwater lighting device such as a strobe is indispensable. At this time, it is desirable that the irradiation direction of the strobe or the light light, which is the lighting device, to the subject, so-called lighting, is to irradiate from above in the same manner as the position of the sun.

In addition, a horizontal composition in which the longitudinal direction of the shooting screen is horizontal is often used for taking underwater photographs of ordinary underwater organisms. This is because a vertical composition with the longitudinal direction as the vertical direction tends to be a bird's-eye view photograph, which is not preferable. Therefore, the camera housing system for underwater photography is configured on the premise that the image is taken in a horizontal composition.

FIG. 6 shows a state in which a conventional camera housing is fixed in a horizontal composition to take a vertical composition, (a) is a photograph showing the camera housing system and a subject, and (b) is a photograph showing the subject. A photograph showing a shooting result, FIG. 7 is a photograph showing a state in which an arm member to which a strobe is attached is extended and deformed to shoot a subject near the bottom of the water in a vertical composition in a conventional camera housing system.

As shown in FIG. 6, in the conventional camera housing system 200, the camera housing 210 is provided with two grip portions 222 and 222 that can be gripped by the photographer with both hands in order to facilitate the handling of the underwater camera. 220 is attached. The strobes 240 and 240, which are lighting devices, are attached to the grip device 220 via the arm members 230 and 230. The camera housing 210 is fixed to the base portion 221 of the grip device 220 with screws or the like.

However, depending on the subject and background conditions, you may want to shoot in a vertical composition. When an attempt is made to shoot a subject that has landed on the bottom 300 in a vertical composition using a conventional camera housing system 200 that comprises a camera housing 210, a grip device 220, an arm member 230, and a strobe 240 on the premise of the above-mentioned horizontal composition. As shown in FIG. 6A, the strobe 240 arranged on the grip device 220 via the arm member 230 comes into contact with the water bottom 300, and the angle between the optical axis O of the lens barrel portion 212 of the camera housing 210 and the water bottom 300. Becomes larger (θ in the figure).

Therefore, it is not possible to take a picture from a position close to parallel to the fish model 90, which is a subject close to the bottom 300, that is, a low angle picture. Further, even if the photograph is taken in the state shown in FIG. 6 (a), as shown in FIG. 6 (b), the light of the strobes 240 and 240 is in a state of being irradiated from the side of the fish model 90. Unlike the natural light from above due to sunlight, it becomes unnatural. Reference numeral 91 in the drawing indicates a transparent pedestal on which the fish model 90 is arranged for taking the photographs shown in FIGS. 6 and 7.

In order to photograph the fish model 90 in the bottomed state from a low angle with natural light, as shown in FIG. 7, additional arms whose angles can be changed to the tips of the arm members 230 and 230 at both ends of the grip device 220. It is necessary to arrange the members 250 and 250 and arrange the two strobes 240 and 240. In such a state, the strobe 240 becomes almost the same height as the camera housing 210, and the fish model 90 can be photographed at a low angle, and the lighting from the strobes 240 and 240 illuminates the fish model 90 from above, which is natural. You can take a picture.

As a technique for changing the arrangement of the lighting device in response to the change between the horizontal composition and the vertical composition of the camera, the following are proposed for the camera used on the ground.

Patent Document 1 discloses a strobe mounting device capable of rotating a bracket to change the position of a strobe when a camera in which a strobe is arranged via a bracket is photographed in a vertical direction.

Further, Patent Document 2 is configured so that the grip can be selectively positioned on the upper surface or the bottom surface and the side surface of the camera body holding the photographing lens, and has a grip in which a strobe light emitting portion is arranged on the upper portion of the grip. Disclose the camera.

Even in the conventional camera housing system, if you want to shoot in the vertical composition while shooting in the horizontal composition, you can change the mounting posture of the camera housing 210 to the grip device 220 to suit the vertical composition. However, in the above-mentioned camera housing system 200, in addition to arranging the grip device 220 in the camera housing system 200, strobes 240 and 240 are attached via arm members, and the dimensions are large, making it difficult to handle and handle in water. Further, the camera housing 210 is fixed to the grip device 220 with screws or the like, and the work of removing the screws or the like and reconnecting the camera housing 210 to the grip device 220 is difficult and time-consuming in water. Therefore, it is realistic to perform such an operation on the ground or on board.

In addition, fish and the like, which are subjects in the water, are usually constantly moving. Therefore, at the time of shooting, it is necessary to instantly hold the camera housing system 200 according to the movement of the subject, and in response to this, the camera housing 210 and the grip device 220 are removed and the posture of the camera housing 210 is changed again to be the grip device.
