ABSTRACT:
A light meter arrangement for a camera having a zoom objective and a view finder. A beam splitter is arranged between the zoom control lens assembly and the relay lens to split off a fraction of the beam of light coming from the assembly and to direct the fraction of afocal form to the view finder. In order to deflect an integral marginal portion of the view finder light beam to a light-sensitive element, there is provided a single prismatic entity having an entrance face positioned adjacent the exit face of the beam splitter. This entity is constructed to have a number of total reflection surfaces arranged to function as a condenser for the light rays passing therethrough.
