Olympus Focusing Screen 1-1, Microprism-matte type.
Standard type focusing screen, suitable for general photography.
Fast and accurate focusing is done on the central microprism spot as well as on the surrounding matte area. The subject is in focus when the jagged pattern of the microprism spot disappears and the spot becomes crisp and clear.
When a lens with a maximum speed of F5.6 or slower is used, the microprism darkens and the focusing must be made on the matte area. The meter needle gives correct light readings.
