ABSTRACT:
A water-resistant camera comprising a frame counter having successive numbered portions for indicating the particular number of exposures remaining for picture-taking, and an optical magnifier for transmitting ambient light beams to the frame counter to form an enlarged image of any one of the numbered portions in order to facilitate viewing the one numbered portion, is characterized in that the optical magnifier is positioned out of optical alignment with at the one numbered portion, and includes an optical wedge that bends the light beams the optical magnifier transmits to the frame counter in order to make the enlarged image of the one numbered portion appear to be optically aligned with the optical magnifier.
