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 ).
