http://nikonrumors.com/2011/04/13/confu ... -lens.aspx This wasn't a rogue division of Nikon doing the posting, it was the main imaging site, so unless the site was hacked, Nikon will be announcing the AF-S 50/1.8G FX lens soon.
Nikon AF-S 50/1.8G now official http://imaging.nikon.com/lineup/lens/si ... /index.htm Est. retail will be $219.95, although with supply issues it may sell for around $300 for some time....
I will get this lens someday as the old version is non-AFS and I have a tendency to get my hands in the way when it is focusing. Ouch! ; :-[
