Pentax AF100P

Pentax AF100P is a direct contact auto flash unit designed exclusively for use with the Pentax AUTO 110 camera in situations where lighting is insufficient for satisfactory results without flash. As a rule, you should use either the AF 100P or a tripod when the yellow indicator lights in the camera's viewfinder, indicating a low-light reading. The flash beam has a wide spread, permitting sufficient flash coverage for lenses all the way down to 18mm. The AF 100P has a guide number of 10 (ASA 100 in meters) and an effective flash range of 0.8 - 3.6 meters (2.6 - 12 ft.).
