Ergo, it is NOT always a good idea to do researching on the internet on your own without others pointing the right direction for you.
Indeed. :bsmilie:
If you search "bokeh" on flickr, it gets even more ridiculous where people go "WOW! Lovely bokeh!!!" or "Great DOF!" and bla bla for who-know-what reasons.
Thanks for your help and to everyone who has chipped in as well, I hope I've understood everything (yeah, I only hope).
To help you "understand" further, you will also want to know that the out of focus regions in front and behind the focal plane are also rendered differently and hence "different bokeh". Some lenses like the Nikon DC (defocus control) lenses allow you to control the size of the circles of confusion (the "bokeh balls" you see) at the front or rear of the focal plane.
