I am still testing the H3D versus the D800 (not necessarily for this forum, I would do it for myself alone) and I tried to compare the bokeh of the two systems. This time I will not be criticised for using a zoom lens, but I will probably be criticised because the two focal length do not match
I used the HC 80mm f/2.8 on the H3D-31 and the Nikon AF-S 50mm f/1.4G on the D800. The pictures are taken from the same point: I took one camera from the tripod and mounted the other one in its place.
The whole set with the pictures is
here. There are two tests, one with flowers and one with a tree.
As expected, the Nikon could get a smaller depth of field because of the much larger aperture (and also because the H3D cannot always use its largest aperture in bright light). The results as to bokeh, on the other end, are less convincing for me, see for yourself if you like them.
The colours are not quite the same, even if the pictures are treated by the same software (and for the flowers the light changed). I did not try to match the colour, I find the difference instructive. On the flower, the D800 focussed on the wrong object (in live view AF mode). I did not try to correct that (I find interesting that the H3D gives better results automatically) and it would not have been easy anyway (I could barely see the D800 screen under the sun, so manual focussing using live view would have been tricky). There is probably also a teaching in that.
On the tree, both cameras focussed on the same point (the lens cap).
People enjoying pixel peeping may download the full resolution pictures using the flickr menus. There is little point, since nothing is really sharp, but I know that some people will want it anyway.
Here an example with the flowers: f/4 on the Nikon versus f/5.6 on the Hasselblad (the pictures are clickable):
