Photo-detection adapter for an automatic flash device

摘要

A photo-detection adapter for an automatic strobe comprising a mounting means attachable to a barrel of a photographic lens, an external photo-detection part supported by the mounting means so as to change a detection direction for properly receiving a reflection light from a photographic object, a light conduction means for conducting the reflection light from the photographic object to a photo-detection element disposed in the strobe, and a coupling means for holding the output end of the light conduction means so as to face to the photo-detection element in the strobe.
