Thank you Dandu
Talking about bokeh, this pic was taken with Canon 40D + Canon 85mm. The 85mm is a great set of lens, I really like it specilally when I use them for portraits. But one of the best features of this set of lens is the bokeh, as you can see on the pic below. A very soft, "rounded" bokeh:

The following pic was taken with the 5D II and the Canon 24-105 mm L. Though it's a L set of lens (the best series of Canon), its bokeh isn't that pretty. The bokeh of the Canon 85mm is way prettier. But I didn't have the 85mm at hand as I took this pic, well, nevermind. It fits the example of a "not so pretty" bokeh
