Expel the "exposure compensation"!
It was around the end of 1977 when Nippon Kogaku K.K. (present Nikon Corporation) started two project teams mainly formed of Camera Designing Dept. (of that time).
The one was the team for developing a high-speed shutter mentioned in the previous part (Nikon FM2) and the other was the team for "Matrix metering" incorporated in Nikon FA to be mentioned in this part.
Nippon Kogaku had been concentrating its effort on the development of technologies for the exposure meter and exposure controlling.
The effort was resulted in the center-weighted metering system, the standard of the TTL metering and the TTL-AE of Nikomat (named Nikkormat in some countries other than Japan(Nippon)) EL series, Nikon EL2 and Nikon FE.
However, there is no "end" in the world of exposure control.
In spite of endeavoring numerous means to advance the accuracy of exposure control and to minimize the failure, we cannot reach the stage of perfection.
For example, though it is possible to advance 96 % of success of the past to 98 %, 98 % to 99.5 %, but it is no way possible to attain 100 % of success.
To avoid a few percent of the remaining failure, advanced users will utilize the exposure compensation or auto exposure lock.
Then what about the not-advanced people ? "Making the exposure compensation or AE lock operation unnecessary", was the object of this team.
