A camera assembly is disclosed which may be implemented on a mail processing system for photographing flats mail items. In one embodiment, the assembly includes lighting components (e.g., light emitting diodes) which are capable of projecting light toward a mail item in a viewing station at a specific angle, which angle may be adjusted to reduce the amount of specular reflection from an item toward a camera. The lighting components may reside in a nose unit which may be easily attached to and detached from the housing for ease of maintenance. The nose unit may be attachable to the housing in a manner which seals the camera and lighting components off from the operating environment, such that airborne dust and debris does not enter the housing or nose unit and damage the camera or lighting components.
