Nikon F2AS Review (3)

Article text
The F2 S Photomic (DP-2 head) and F2 SB Photomic (DP-3 head) also accepted the unusual Nikon DS-1 or DS-2 EE Aperture Control Units. The F2 AS (DP-12) required the equivalent DS-12. These were early attempts by Nippon Kogaku to provide shutter priority autoexposure by having an electric servomotor automatically turn the lens aperture ring in response to the set shutter speed and light meter reading. The DS-1, -2 and -12 were bulky, slow and unreliable, and were feeble and inelegant attempts to add autoexposure to the manual exposure F2.
