By Michael Myers

The G is quite a bit larger.

The iris diaphragm on the G has smoother edges.

The camera used for the comparison photos was a Nikon D80.

I used aperture priority single area autofocus for all shots, aiming the focus point at the same spot for all comparisons- I felt that was the best way to ensure uniformity. Sometimes the G made a slight difference in shutter speed exposing 1/3 stop longer.

For all comparison photos, as above, the G is on the left and the D is on the right.

Not much difference in bokeh at f/1.4 but the resolution of the D seems better.

Closing the aperture a bit, the D seems better saturated, and you can see the advantage of the G's iris diaphragm in the out-of-focus highlights.

Pretty much even at f/8.

More severe red fringing on the G at f/4, not on the D.
