The invention relates to a method and apparatus for capturing a low depth of focus image with a video camera (10) by forming a first image of a scene, with a first image format size, onto a projection area (16), housed inside an adaptor, and forming another image of the scene, with a second smaller image format size onto a semiconductor sensor field (28), housed inside the video camera (10). The invention further relates to configuring the projection area (16) to prevent non-image characteristics of the projection area from being imaged in a disturbing manner onto the semiconductor sensor field (28). The projection area is either movable with respect to the first image or encapsulated by clear filter glass, or both to prevent the non-image characteristics from being imaged in a disturbing manner. The adaptor includes an adaptor housing (30′) for attaching to the video camera (10) and the adaptor housing houses the projection area (16) and a first objective lens (12).
