Determined by how black the back ground is (darker usually = better) you might have to dialin some exposure payment to really get your bokeh to essentially place. Next, try getting an interest blurry background with a kit lens of some sort before the camera at the minimum focus range (or there about) together with the bokeh highlights within the history.

But it's possible to completely change your lens by simply adjusting the way where it is used by you.
