An active auto focus system in which a beam of modulated energy is projected towards a subject to be focussed upon with the energy reflected therefrom directed towards a detector array. The detector array comprises a number of radiation responsive elements arranged in parallel rows and in a pattern which permits the reflected energy to impinge upon at least one detector in each of the rows simultaneously. The arrangement allows a digital type output indicative of the position of the reflected energy on the array and thus the position of the subject from the camera.
