Late model Konica Hexanon AR lenses are all black, and are those mostly commonly found. However, older Konica lenses are black with a silver colored aperture ring, and can still be found on occasion. In addition, some early Hexanon AR lenses were ARP (preset) or ARM (manual). ARM lenses are also ones which take a put-in type filter at the rear of the lens. All others use filters which screw onto the front of the lens.
