发明名称 Watertight camera
摘要 A watertight camera is disclosed in which the normal line of a transparent protection plate for an objective of the finder, or the normal line of a protector for the strobe, is inclined toward the axial direction of the photographic lens. While there is no interference during in-the-air photography, underwater photography is carried out more advantageously.
