发明名称 CAMERA AND ITS ATTACHMENT LENS
摘要 PURPOSE:To automatically obtain correction information by providing an information generating means which gets each correction information obtained by considering distance information and an action for decreasing a strobe light quantity changed in response to the detection output of a detection means which detects that an attachment lens is mounted. CONSTITUTION:The detection means 4 is provided, which is constituted to discriminate the mounting of an attachment lens unit 9 equipped with a defuser part 8 for a flash light emitting means 3. The correction information generating means is also provided so as to get the correction information on the distance information obtained by the range-finding means of a camera and the correction information obtained by considering the light decreasing action for the flash light emitting means 3 of the camera by the defuser part 8 in response to the output of the detection means 4. Thus, the correction information for a distance information means and/or the flash light emitting means appropriate for respective units is automatically generated.
