35mm doesn't equal 52mm on a DX camera. It has the same field of view as 52mm on a full-frame camera, but it will still have the distortion of a 35mm lens.
As far as a 50mm goes I have the f/1.8D lens, and I was just using it a couple of hours ago, wide open. I find out of all my lenses, it preforms the worst wide open. Not as sharp and with relatively bad chromatic aberration. Just wondering if the G lens is any better in this respect, and if so I would probably recommend spending the extra cash.
