Abstract
Abstract A snorkel camera system that has a prime lens connected to one end of the housing and a camera body connected to the other end of the housing, the optical axis of the prime lens and of the camera body being offset and parallel, and the housing is detachably mounted to the camera body such that the housing can be rotated about the camera body to a desired position and locked in place, the optical system being such that the image seen in the viewfinder maintains the correct attitude regardless of the position to which the prime lens is rotated.

Claim 1
Independent Claim
346 words
A snorkel camera system comprising a camera body means having a camera housing with a light admitting opening therein, means for recording images transmitted through said light admitting opening, and an eyepiece having a lens therein for viewing the object being photographed; an elongated hollow housing means having one end arranged for light entry and the other end for light egress, and camera mounting means connected to the light-egress end of said housing means for detachably mounting said camera body means at said light admitting opening; a prime lens detachably secured to the light entry end of said housing means and facing in the same direction as said light admitting opening and optical means for providing an optical path from said prime lens through said hollow housing means to and through the light admitting opening of said camera body means, said optical means comprising a 90° prism means in said housing means adjacent said light entry end and operable to turn said optical path through an angle of 90°, a penta prism means adjacent said light egress end and having a first face disposed toward said 90° prism means and a second face perpendicular to said first face and disposed toward said light admitting opening of said camera body means, said penta prism means being operable to turn said optical path through an angle of 90°, whereby an erect non-reversed image of the object is viewed through said eyepiece; and connector means carried by said housing means at said light egress end for connecting said camera mounting means to said housing means, said connector means comprising tubular means having one end connected to said housing means at said light egress end, said camera mounting means being connected to said tubular means, said optical path passing from said penta prism means to said camera body means via said tubular means, said tubular means and said camera mounting means having cooperating members operable to allow said housing means to be rotated relative to said camera mounting means while said camera mounting means remains connected to said tubular means.
