閃光照射角可変式ストロボ。[Claims for Utility Model Registration] (1) A strobe capable of selectively changing the flash irradiation angle, which includes a flash discharge tube and an aperture that surrounds the flash discharge tube and emits a flash light in part. A plurality of reflective members having a perforation and a reflective surface formed on the inner surface and condensing optical systems with different condensing degrees are arranged approximately along a rotation trajectory passing outside the reflective member, and among these condensing optical systems, A variable flash illumination angle type strobe comprising: a variable illumination angle means rotatably arranged so that one of the means is selectively positioned at a position covering the front surface of the aperture. (2) The illumination angle variable means is interlocked with a switching member for switching the focal length of the photographing lens, which can switch the focal length in multiple steps, between a short focal length side and a long focal length side. When operated, the condensing lens corresponding to the angle of view on the short focus side is positioned at the aperture for emitting flash light, and when the switching member is operated to the long focus side, the angle of view on the long focus side is set. The variable flash illumination angle strobe according to claim 1, characterized in that another corresponding condensing lens is positioned in the aperture.
