The Nikon EL2 was manufactured from 1977 to 1978 and was essentially identical to the ELW, but with the addition of instant response silicon photodiode light meter sensors and support for Nikkor lenses with the new Automatic Indexing (AI) feature.
The EL2 also abandoned the Nikkormat name (the Nikkormat FT3 being the last of the Nikkormat line) which had distinguished these cameras from the better known Nikon-badged models. The Nikon EL2 was replaced after a year of production by the Nikon FE.
