NOBLEX cameras use the principle of a lens rotating 360? for one exposure. The film, resting on the curved film plane, is exposed through the constant shutter slit. During the first half of the rotation the lens drum is accelerated to a constant speed insuring absolutely even exposure of the film during the second half of the rotation. This results in distortion free photographs with an angle of view of 146? when using a NOBLEX PRO 6/150 . What makes these pictures stand out are their remarkably even edge to edge illumination and unsurpassed sharpness. The photographs correspond to the natural space perception of the human eye.
