Abstract
A one-piece lens hood possesses a frontal surface having an approximately rectangular opening, is axially displaceable via a guide from a position of rest into a working position, and is indissolubly connected to the lens. In the position of rest, the frontal surface of the lens hood terminates flush with the front edge of an accessory mount so that the threaded portion of the accessory mount is readily accessible for screwing in accessories such as filters. A format stop is additionally provided as an integral part of the lens in order to mask out stray light. This can, for example, be formed from a blackened metal foil which is mounted on a front terminal ring of the lens.
