Nikon 50 1.8G officially announced

Check out the product page: http://www.nikonusa.com/Nikon-Products/Product/Camera-Lenses/2199/AF-S-NIKKOR-50mm-f%252F1.8G.html   Key differences in specs from 50 1.8D: - This is an AF-S lens meaning it has a silent wave motor (SWM).  Can autofocus on entry-level Nikons that don't have a focusing motor.  Should focus quickly and quietly. - M/A switch.  Allows manual override of autofocus. - Has one aspherical element, which should reduce aberration. - As a G lens, it doesn't have an aperture ring.  On some film bodies, aperture can't be controlled in A or M mode (it can be indirectly controlled in P or S mode). - Minimum aperture f/16 vs. f/22 for the 1.8D. - Filter size 58mm vs 52mm for 1.8D. - The product page makes a big deal about the bokeh.  I'm no bokeh hound but will be looking into this. - The product page mentions Super Integrated Coating (SIC) to reduce flare but even the 1.8D already has that. - MSRP: $220 vs. $135 for the 1.8D.
