As you have probably gathered from the (helpful) replies and the linked articles, because depth of field increases as the distance increases, the answer is:

Even with your aperture open all the way, you will need a very long focal length to get a narrow depth of field.

Then the problem arises that generally long focal length lenses don't have particularly large maximum apertures.

So the best you can do is use your longest lens and your largest aperture. If you have some very expensive lenses you will be able to get what you described.

Guys if you would like to what is DOF THIS link would be better otion that my Spanglish :D

For those who would like to have a good reference page bookmark THIS link in your PC ;)

Cheers

and while it's not technically DoF, put the subject a long way away from the background but close to the lens which helps to achieve the same effect.
