Sample photos
Digital Camera Watch at Impress has posted a nice set of full-resolution portraits and sample photos, shot with the 28mm F1.8G mounted on a Nikon D800.
The official 28mm f/1.8G image samples are not at full-resolution, but give you a pretty good idea of the kind of bokeh you can get with this lens.
