In addition to the rumored 18-300mm f/3.5-5.6 (see patent) and 16-85mm f/4 (see patent) DX lenses, Nikon will also announce a new Nikkor AF-S 28mm f/1.8G full frame lens. The new lens will not have VR and it will be small in size (I guess compared to the 24mm and 35mm f/1.4 versions). I don’t know the exact announcement date, but I believe it will be this year (2012).
Nikon discontinued the very popular Nikkor 28mm f/1.4D AF (read more about it here) long time ago – this lens is still selling for record amounts on eBay.
