Claims

[Scope of claim for utility model registration] (1) An aperture knob for aperture operation and a distance knob for distance operation are protruded from the side of the casing of the lens body,
When installing an underwater camera in which the distance scale and aperture scale are read from the front of the lens body, a mounting tube is rotatably fitted around the outer periphery of the casing, and a distance ring with the distance scale displayed on the outer periphery is attached. An aperture ring with an aperture scale displayed on the outer circumference is rotatably fitted to the outer periphery of the inner cylinder, and an aperture ring with an aperture scale displayed on the outer periphery is rotatably fitted to the outer periphery of the distance ring. The engagement gear of the aperture rotary knob fixed to the aperture knob is engaged with the engagement gear formed on the edge of the aperture knob, thereby making the aperture ring rotatable and fixing the aperture ring to the distance knob. An adapter for an underwater camera characterized in that the distance ring is made rotatable by meshing and engaging the mating gear with a meshing gear formed on the edge of the mounting tube of the distance ring. (2) A depth ring for displaying depth of field is rotatably fitted into the middle tube along with an aperture ring, and the aperture ring and depth ring are rotatably supported by an engagement gear on the middle tube. The adapter for an underwater camera according to claim 1, which is a utility model, and is capable of displaying the depth of field as the aperture ring rotates. (3) The underwater vehicle according to claim 1 of the utility model registration, characterized in that the distance scale display of the distance ring is formed on the tapered part of the outer surface of the hood so that it can be easily checked when looking through the viewfinder. Camera adapter.
