Does anyone know why there is so much price difference between the El-Nikkor 135mm (about $375-$400) and the 150mm (around $800)?

The lenses may be completely different designs. The 135 may be only 4 elements and the 150 may be 6. Or the 150 may be an APO design. The only way to find out for sure is to look at the specs for the two lenses. Maybe they are on the Nikon website?
