Abstract
A photometry device having a block body, constructed as a single body, on which all of the elements of a photometry system are mounted. The photometry system includes a condenser lens, a stop plate having a stop and a photosensor. An output characteristic of the photo sensor is determined by a pre-set resistance provided in a circuit board, and is adjusted during the process of assembling the block body. The photo sensor does not require a re-adjustment after the block body is assembled into a camera.
