A storage portion is provided in a body protector that has a waterproof space for storing a camera. A shoe cover that is removed from a hot shoe of the camera is put away into the storage portion. The storage portion is formed in a corner of the box-shaped waterproof space in the body protector. The shoe cover can be inserted into and removed from the storage portion in the optical axis direction of a camera lens.

Provided in the present invention are a leader for fly fishing comprising a monofilament of a vinylidene fluoride resin, said leader consisting of a butt section, a taper section and a tippet section, a diametral unevenness of the tippet section being less than 10%, and a process for producing such a leader for fly fishing. The leader for fly fishing according to the present invention has pliability to allow unrestricted movement of the fly and enough strength to withstand the impact of striking, and is also small in diametral unevenness and capable of having its curling disposition or kink easily straightened out.

A waterproof protector system comprises a body protector which stores a camera body, a first port member to be attached to the body protector, and a second port member to be attached to the first port member. The body protector is formed having a first opening portion. The first port member has a second opening portion to be fitted in the first opening portion, a third opening portion larger in diameter than the second opening portion, and a conical barrel portion formed between the second opening portion and the third opening portion. The first port member houses an accessory member, such as a wide-conversion lens. The second port member has a fourth opening portion, fittable in the third opening portion, and a light transmitting portion.
