F2A (DP-11 Photomic Finder)

The DP-11 on a Nikon F2 makes a F2A. But it carries more meaning than that. It was in 1977, where Nikon has introduced five camera bodies within the same year, F2A,
F2AS, Nikkormat FT3, Nikon EL-2 and the new compact FM.

Note: The information contained herein is quite basic; if you want to find out MORE information relating to this metered prism; you may go to the Nikon F2 site and look for THREE sections:

The previous coupling method of attaching a lens for proper metering was replaced with a revolutionary mechanical mean called "AI" (Automatic Maximum Aperture Indexing), where you need not have to align the aperture value on the lens in use to preset position before mounting for proper metering. This system proved to be extremely effective, reliable and responsive than the previous way. Camera equipped with AI-spec also takes older Non-AI Nikkor lenses, but only limiting to use stopped down exposure measurement instead of the full aperture TTL metering. More importantly, the AI has positioned Nikon back to the forefront of technological innovation to apply their best optical design and application in mechanical engineering for their cameras and lenses.

The DP-11 finder housed a pair of light sensitive sensors (Cds) that read the brightness over the entire area of the viewing screen, but concentrate 60% of their sensitivity on the 12mm diameter circle in the center. And the system used is uniform with all lenses to assure reliable, accurate exposure determination.

Meter sensitivity range is from EV 1 to EV 17, (1 second at f/1.4 to an exposure of 1/2000 at f/8, f/1.4 lens and ASA 100 film). Correct exposure is determined by match needle centering method and exposure information (shutter speed in used - in the case of AI lenses; Non-AI lenses in stop down mode); aperture value used is visible below the picture area. Other features include a built-in flash ready light, stop-down metering, automatic maximum aperture indexing and a reference exposure meter on top. Adding all these features found on the DP-11 and mount it to the F2 basic body, and you have a Nikon F2A.
